device, and follow all instructions included therein.
The operating instructions should be made available to all users.
Observe the following safety precautions:
• The instrument may only be connected to a 230 V or 120 V
electrical system (depending on the country-specific design)
which is protected with a fuse or circuit breaker with a maxi-
mum nominal current rating of 16 A.
• Be prepared for the occurrence of unexpected voltages at de-
vices under test (for example, capacitors may be dangerously
charged).
• Make sure that connector, measurement and test cables are
not damaged (i.e. broken insulation, kinks, interruptions etc.).
• The instrument may only be used indoors.
• Impulse withstand voltage of up to 2.5 kV may occur in
measurement category II systems with 230/400 V.
• If only the batteries are to be charged (instrument is ready for
operation in SETUP position), please ensure that the test in-
strument cannot be used by unauthorized personnel during
the charging process.
• Measurement may only be performed on voltage-free equip-
ment and devices.
• Measurements may not be performed under moist ambient
conditions, where condensation has occurred, or in explosive
atmospheres.
• Do not disconnect the measurement cables until the device
under test has been fully discharged.
• Observe accident prevention regulation BGV A3, “Electrical
Systems and Equipment”.
• Do not perform measurements alone: always have a second
person help if possible.
• Make sure that measurement cables are connected correctly.
• Do not touch the test probes at any point beyond the finger
guard.
The MERISO PRIME+ may not be used:
• If visible damage is apparent
• With damaged connector, measuring or test cables (test ca-
bles may not, under any circumstances, be mechanically dam-
aged or kinked, because impaired insulation characteristics
may otherwise result)
• If these no longer function flawlessly
• If the signal lamps on the PROFITEST204HP/2.5kV
(feature B1) and PROFITEST204HV/5.4kV (feature B2) high-
voltage modules are defective
In such cases, the devices must be removed from service and
secured against any possible inadvertent use.
Send the instrument to our Repair and Replacement Parts service
department in such cases (see chapter 12 on page 67).
GMC-I Messtechnik GmbH 11
Opening of Equipment / Repair
The equipment may be opened only by authorized service per-
sonnel to ensure the safe and correct operation of the equipment
and to keep the warranty valid. Even original spare parts may be
installed only by authorized service personnel.
In case the equipment was opened by unauthorized personnel,
no warranty regarding personal safety, measurement accuracy,
conformity with applicable safety measures or any consequential
damage is granted by the manufacturer.
2.1 Checklist for High-Voltage Tests
Attention!
!
Measurements may not be performed under moist ambi-
ent conditions, where condensation has occurred or in
explosive atmospheres.
Personnel Safety
Ð Turn the machine under test off and lock it in the off position.
Ð Perform insulation resistance measurement.
Ð Make sure that the system is grounded.
Ð Secure the danger zone with barriers, closing even narrow en-
trance ways.
Ð Set up warning signs such that they are plainly visible.
Ð Set up warning lamps such that they are plainly visible.
Ð Attach the emergency stop button in a plainly visible fashion.
Ð Warn personnel working in the area of possible danger.
Ð Always turn the test instrument off with the key switch and re-
move the key before leaving the work area.
Safety Precautions for the Machine Under Test (recommended)
Ð
Review the circuit diagrams and make a note of all electrical circuits.
Ð Disconnect the neutral conductor from the mains.
Ð Short circuit each electrical circuit to itself.
Ð Disconnect control circuits with overvoltage arresters, if the ar-
resters would be triggered by utilized test voltage.
Ð Disconnect PELV circuits (no high-voltage testing is required
for these circuits).
Ð Test insulation at each circuit with 1000 V.
(If insulation resistance is OK at 1000 V, no failures should
occur during the high-voltage test.)
Ð Disconnect frequency converters.
Ð Caution in TN systems!
The protective conductor is connected to the neutral conduc-
tor in the junction box. High-voltage is thus applied between
the phase conductors and the neutral conductor.
The neutral conductor must be cut if necessary, because it is
not disconnected from the mains by means of fuses.
Setting Up the Test Instrument
High-Voltage Test
Ð
Test all circuits (conductors) against the protective conductor (all
switches in the mains circuit must be turned on, and testing must be
performed upstream and downstream from all relays and contactors).
Ð Remove all shorting devices after testing has been completed.
Testing Without Short-Circuiting
Ð Separately test all conductors from all circuits against the pro-
tective conductor (the machine could be damaged in the case
of arc-over).
Functions Test
Ð The machine must be tested for correct functioning after the
high-voltage test, especially as regards safety functions.

2.3 Special Safety Precautions and Instructions
for Feature B1/B2
Precautions for the prevention of unauthorized start-up:
•Key switch
Precautions for the prevention of inadvertent start-up:
• Multiple key operation:
Before test voltage can be applied to the test probes by acti-
vating the trigger at the high-voltage switching pistol, the
START key must be pressed at the primary device.
• Two-hand operation:
Each of the high-voltage pistols is equipped with a trigger.
Both triggers must be activated simultaneously in order to ex-
pose both test probes.
• High-voltage switching pistol (pistol with yellow marking) with
double safety feature:
If the trigger at the high-voltage switching pistol is pulled to the
first point of mechanical resistance, the test probe is exposed.
High-voltage is not applied to the test probe until the trigger is
pulled beyond this point, assuming the device is switched on.
General Safety Precautions
• Integrated signal lamps indicate the switching status of the test
instrument.
• Test probes are electrically isolated from the mains:
This prevents current from flowing from the high-voltage
switching pistol to earth.
• Current limiting in the event of arc-over:
If the current limit value entered as a device parameter is ex-
ceeded due to arc-over, switching to the “standby” mode
takes place automatically.
•When mains voltage is restored after a power failure, switching to
the “standby” mode takes place automatically.

ment, make sure that all means of access to the danger
zone are closed, and that all persons have exited the
danger zone.
Attention High-Voltage!
When the trigger at the high-voltage switching pistol is
pulled to the first point of discernible mechanical resis-
tance, the test probe is exposed.
If the trigger is pulled beyond this point of mechanical re-
sistance, high-voltage is applied to the test probe, as-
suming the high-voltage module is in the “standby”
mode.
Attention High-Voltage!

during the high-voltage test!
Life endangering high-voltage of up to 5.35 kV is present at
the test probes of the high-voltage module!
Limitation of Liability
PCs located in proximity to the test equipment may “crash” in the
event of arc-over, resulting in possible data loss. All data and pro-
grams should be suitably saved, and computers shut down
before performing the high-voltage test. PCs may crash even if no
RS 232 connection has been established.
The manufacturer of the test instrument assumes no liability for
direct or consequential damages to computers or peripheral
devices, or for data loss during performance of the high-voltage
test.
Furthermore, the manufacturer assumes no liability for defects at

3 Initial Start-Up
The MERISO PRIME+ test instrument is supplied with a base
which serves as a compartment for storing test cables, the guard
cable (feature G1), the test probes and the battery pack
(feature C1).
Attention!
!
The test instrument may only be operated if the
base is properly attached and secured.
3.1 Battery Operation, Feature C1 (not with B1/B2)
The battery pack is required for operation of the MERISO
PRIME+ without mains power. The battery back includes 8 NiMH
batteries. No other battery packs may be used.
The battery pack is charged automatically by the integrated mains
power pack. Optional use of an automotive charging adapter is
also possible. The device must be switched on in this case (any
switch position other than OFF).
Attention!
!
If only the batteries are to be charged (instrument is
ready for operation in SETUP position), please ensure
that the test instrument cannot be used by unauthorized
personnel during the charging process.
3.1.1 Removing the Device Base and Inserting or Replacing
the Battery Pack
Please observe instructions included in this chapter if the device
is to be retrofitted with a battery pack, or if the battery pack
requires replacement.
Attention!
!
Before dismantling the device base:
– Disconnect the device from the measuring circuit at all
poles.
– Disconnect the device from mains power.
– Turn the device off (set the switch to OFF).
Ð Close the cover and position the handle at the side of the de-
vice.
Ð Turn the device upside down, i.e. place it onto its cover.
Ð Unwind the test cables from the cable uptake at the side.
Ð Remove the guard cable from the device base if one is in-
cluded (feature G1).
Ð Loosen the three Phillips head screws at the bottom of the de-
vice base.
Ð Lift the device base up, and set it down at the side of the de-
vice with the feet at the bottom.
Ð Place the battery pack onto the two rubber cushions in the re-
cess in the device base such that the connector cable with
plug connector from the battery pack is on the same side as
the device’s connector cable with socket connector.
Double-check: The opening at the side of the base coincides
with the device’s connection panel.
16 GMC-I Messtechnik GmbH
Ð Connect the two cables to each other and secure the connec-
tion with the snap hooks.
Ð Position the cable such that is cannot be pinched during sub-
sequent assembly.

with washers. Longer screws may reduce creepage dis-
tances or damage the device.
If a battery pack (feature C1) has been installed and the device is
not connected to the mains, the battery symbol appears at
the display when the device is switched on, and the number of
dark bars displayed in the symbol indicates the battery charge
level.
After installing the battery pack, the device is automatically sup-
plied with power from the batteries.
3.2 Initial Start-Up with Feature B1/B2
3.2.1 Retrofitting Feature B1/B2
Retrofitting with a high-voltage module (feature B1 or B2) can only
be performed by GMC-I Service GmbH.
The MERISO PRIME+ serves to determine the insulation value in
a non-destructive manner. If it is too low, it is possible to detect
the weak point with the high-voltage module (B1 or B2).

3.2.3 Indication of Operating States
Signal Lamps at the High-Voltage Module
The signal lamps integrated into the high-voltage module indicate
two different operating states:
Green: Test instrument ready for use
• Key switch is in the “I” position (ON).
• Power supplies for signal and control circuits at the
high-voltage module are switched on.
• Test voltage supply circuits are still switched off, and are still
secured against inadvertent activation.
Attention!
!
All safety precautions required before entering the dan-
ger zone must now have been implemented, amongst
others: set up WS1 warning signs and ZS2 auxiliary
signs in accordance with DIN 40008, part 3.
Red: Instrument ready for operation, caution: danger!
• The menu for starting the voltage test has been opened, and
the START key has been activated.
• The power supply circuit for the safety test probe is still
switched off, assuming the trigger has not been pulled at the
high-voltage pistol.
• The test probes are secured against inadvertent contact, as-
suming the triggers at the high-voltage pistols have not been
pulled.
Attention!
!
All means of access to the danger zone must be closed
when the high-voltage module is in the “standby” mode!
The device must be sent to GMC-I Service GmbH in order to
replace lamps.
External Signal Lamps (feature F1)
The external signal lamps indicate the same operating states as
the signal lamps integrated into the high-voltage module. They
provide additional security at the test site, and must be plainly vis-
ible beyond the boundaries of the danger zone.
The external signal lamps can only be connected to the 12 V/5 W
output jack at the high-voltage module (feature B1 or B2).
Note
For reasons of safety, only Z504D signal lamps available
from GMC-I Messtechnik GmbH may be used.

4 Performing Tests
Each of the following tests is automatically assigned to one cur-
rently available object number. Any given test which is saved to
memory with the “STORE” key is stored with reference to this
number. The object number can be entered in the “DUT data”
menu (see chapter 5.1 on page 48).
Measuring mode operation is always carried out according to the follow-
ing sequence:
• Select the desired test.
• Enter test parameters (if required).
• Start the measurement or return to the initial menu.
• Save measured values to memory and enter a description
(if desired).
Observe the following for all tests:
• Safety features and precautions, see chapter 2.
• Disconnect the device under test from all sources of voltage
first.
• Test for absence of voltage.
• Do not disconnect the measurement cables until the device
under test has been fully discharged.
4.1 Insulation (resistance) Test
Test voltage can be set between 100 V and 5,000 V for this test.
This voltage, as well as the allowable limit value for insulation
resistance, can be selected as a test parameter.
Voltage at the device under test appears at the LCD in addition to
measured insulation resistance.
Discharge
After the measurement has been completed, the device under
test is discharged automatically in order to assure zero voltage.
The falling voltage value can be observed at the display during the
discharging process. The measured insulation resistance value
remains in memory during this period of time.
Interference Voltage
If voltage is present at the test probes after mea-
surement is started, an “external voltage” warning
appears at the display. The level of the interference
voltage is shown at the display. The insulation test is aborted after
the test probes have been removed from the DUT. The test has to
be conducted again on the de-energized DUT.
30 GMC-I Messtechnik GmbH
Attention!
!
Do not touch the test probes during measurement!
A direct voltage of up to 5000 V is present between the
test probes.
Note
Testing the Measurement Cables:
Initial testing should be performed after short-circuiting
the measurement cables with their test probes. The
instrument should display nearly zero MΩ. A broken mea-
surement cable can be detected in this way.

4.1.4 Data logger function (min log)(as of firmware version AH)
MENU
Select Parameter
If you choose time parameter setting "min log" from the menu,
exactly 30 measured values are automatically stored during the
selected test duration at time intervals between 4 seconds and
2 minutes. This makes data logger operation possible for measur-
ing durations between 2 and 60 minutes. In this case, the residual
time of the current measurement is not indicated in seconds, but
in minutes. While the test is being performed, icon “Stored” is
briefly shown in the display and the yellow signal lamp “Testing ...”
disappears briefly each time a measured value is being stored. If
the signal generator is activated, an acoustic signal sounds addi-
tionally.
In this function, the current test time is stored for each measure-
ment instead of the parameter for the test duration to ensure the
temporal correlation between measured value and time of mea-
surement.
Note
Before the start of each test with data logger as
described in chapter 5.1, select a new device under test
to avoid the measured values being stored successively
within the same DUT.
This considerably facilitates the subsequent evaluation of
the stored measured values.

4.1.5 Measurements with the Guard Cable (feature G1)
The measurement of very high resistances necessitates extremely
minimal measuring current and may be rendered problematic as a
result of influences such as electromagnetic fields, humidity or
surface current. An accurate test set-up is thus absolutely essen-
tial.
A guard cable must be used for measurements within a range of
100 GΩ (10 GΩ) … 1TΩ, in order to prevent surface current from
distorting measurement results. The guard rings prevent current
at the surface of the insulation material from flowing from the
+measurement cable to the –measurement cable, instead of
through the insulation material itself.
Ð Insert the plug from the guard cable into the appropriate jack in
the test instrument.
Ð Plug the alligator clip onto the guard cable test probe.
Ð Connect the alligator clip to the guard ring between the two
measuring points at the insulation material under test.
Ð Refer to chapter 4.1.2 on page 31 regarding the measuring se-
quence

The following materials can be used as guard rings: alu-
minum foil, copper foil or metallic hose clamps.

withstand a test voltage of twice its own rated voltage value or
1000 V~ (whichever is greater) applied between the conductors of
all circuits and the protective conductor system for a period of at
least 1 second. The test voltage must have a frequency of 50 Hz,
and must be generated by a transformer with a minimum power
rating of 500 VA.
Note
Feature B must be included for testing in accordance
with DIN VDE 0113.
Feature B2 is used for testing at up to 5 kV.
The MERISO PRIME+ automatically recognizes which type of high-voltage
module has been connected. Communications between the test instrument and
the high-voltage module can be tested as described in chapter 3.7.4.

4.2.4 Pulse Control Mode
We recommend selecting the pulse control mode for
troubleshooting purposes (arc-over pinpointing).
Interrupting current I
MAX
is fixed to a value of approximately
125 mA with feature B1, and to approximately 5 mA with feature
B2 in the pulse control mode. If this value is exceeded, test
voltage is switched off within 0.5 ms. After approximately 0.6 s,
test voltage is increased from 0 to its final value within a period of
0.2 s, or is switched back off if interrupting current is exceeded.
Ð Set I
MAX
to >>>>>>> in order to activate the pulse control
mode (see chapter 4.2.2 on page 36).
Ð If continuous operation is required, set test duration to >>>>>>>
as well (see chapter 4.2.2 on page 36).
4.2.5 Ending the High-voltage Test
Ð Release the triggers at the high-voltage pistols.
Ð Press the MENU key.
Ð The signal lamps change from red to green.
Ð The test system must be removed from service (signal lamps
off) if left unattended.

4.3 Polarization Index Measurement
A polarization index test is recommended for electrical machines.
This procedure involves expanded testing of insulation resistance.
DC measuring voltage from the MERISO PRIME+ is applied to
the insulation for a duration of 10 minutes. Measured values are
documented after one minute, and after ten minutes. If the insula-
tion is good, the value measured after ten minutes is higher than
the value measured after one minute. The relationship between
the two measurement values is the polarization index. Charged
material within the insulation is aligned due to the application of
measuring voltage over a long period of time, resulting in polariza-
tion. The polarization index indicates whether or not the charged
material contained in the insulation can still be moved, thus allow-
ing for polarization. This, in turn, is an indication of the condition of
the insulation.
The following rules apply in general:
PI values < 1 Troubleshooting is required.
PI values = 1 … 2 Maintenance is recommended.
PI values = 2 … 4 DUT is OK, no immediate action is
required. Preventive maintenance can be
planned according to the number of tests to
be performed.
PI values > 4 DUT is in flawless condition.
Applications
Determination of moisture and contamination levels
Absorption Index (DAR)
– DC Charging Test
The absorption index test is part of the polarization index test.
Insulation resistance measurements are placed in relationship to
one another after 30 and 60 seconds.

age by charging with constant current. The measurement is per-
formed with automatic range selection. One of the nominal test
voltages (U
nom

var
) can be
used.
Dielectric Discharge Test (DD)
This test was developed for use with large machines and is per-
formed, as its name indicates, during discharge. It designates the
ratio of the discharge current after one minute and the product of
voltage by capacitance:
DD values > 4: Troubleshooting is required
DD values = 2 … 4 Maintenance is recommended
DD values < 2 DUT is OK, no immediate
action is required.

4.6 Voltage Measurement (protection against residual voltage)
EN 60204 requires that voltages in excess of 60 V occurring at all
accessible machine components during operation must drop to a
residual voltage value of 60 V or less within a period of 5 seconds
after supply power has been switched off.
Testing for the absence of voltage is performed by means of a
voltage measurement which involves measuring discharge time
with the MERISO PRIME+. Elapsed time as of disconnection
from supply power is displayed continuously at the LCD during
discharge, until the limit value of 60 is reached.
In addition to voltage type (AC, DC or AC+DC), frequency is mea-
sured and displayed as well. The mean value is always read out.
In addition to voltage and frequency, voltage type (AC, DC or
AC+DC) appears at the symbol field in the display.
If voltage drops by more than 5% of the measured value during a
single measuring period (approx. 0.7 sec.) while performing a volt-
age measurement which results in a value of greater than 60 V, a
time measurement is started automatically in order to test protec-
tion against residual voltage. This time measurement can be
observed at the display in the symbol field. Time measurement is
stopped after voltage drops to below the limit value of 60 V. Time
required to discharge down to 60 V then appears at the display in
seconds. Voltage measurement continues until maximum allow-
able discharge time has elapsed (normally 5 seconds). The results
of the voltage measurement are then “frozen”, and the
DATA HOLD symbol appears at the display. If the 60 V limit value
is not reached before allowable discharge time has elapsed, the
voltage value is “frozen” and time measurement continues until
the 10 second time limit has elapsed. If voltage is still greater than
60 V after 10 seconds, the test is aborted and the instrument
restarts voltage measurement.
When the display is “frozen”, voltage measurement is not started
again until:
• The START key is pressed.
• The measured value is saved to memory by pressing the
i/Store key.
• Voltage measurement is restarted from the menu.
• Or voltage at the test probes climbs back up to a value of
greater than 60 V, or if the next measured value after a mea-
surement of greater than 60 V is even higher, i.e. if a climbing
tendency can be observed.
Both elapsed time and the prevailing voltage value after allowable
discharge time has elapsed are saved to memory by pressing the
i/Store key. If no discharge takes place, only the voltage value is
saved.
Note
If, for example, conductors are exposed when a machine
is switched off – e.g. if plug connectors are disengaged –
and if these are not protected against direct contact,
maximum allowable discharge time is 1 second!

4.6.1 Setting Test Parameters
The discharge time during which the voltage value must drop to a
non-hazardous value of less than 60 V can be specified as a limit
value between 1.0 and 9.00 seconds. The following message
appears in order to indicate that the limit has been reached:
“residual voltage less than 60 V!”.
Set Discharge Time
Test duration is always set to continuous measurement in this case
because residual voltage testing is triggered automatically and
voltage measurement is always active for safety reasons.

10 Maintenance
10.1 Replacing the Mains Fuse
Attention!
!
Disconnect the device from the measuring circuit at all
poles before opening the fuse compartment!
Disconnect the device from the mains.
Attention!
!
Use only specified, original replacement fuses!
Bypassing or repairing fuses is prohibited!
If fuses with other current ratings, breaking capacities or
blowing characteristics are used, the device may be
damaged!
Ð Open the fuse compartment at the inlet socket with a suitable
tool (e.g. a screwdriver).
Ð Replace the blown fuse with a new fuse with identical specifi-
cations.
Ð Close the fuse compartment.
10.2 Testing of Rechargeable Batteries
Check the batteries for leakage or damage at short regular inter-
vals, and after long periods of storage. If damage or leakage has
occurred, carefully and completely clean the electrolyte from the
instrument with a damp cloth, and replace the batteries with a
new battery pack (accessory no. …..) before placing the instru-
ment back into service.
If the battery test (see chapter 3.7.4 on page 25) indicates that backup
battery voltage or rechargeable battery voltage has dropped below the
minimum allowable value, recharge the battery pack or have the backup
battery replaced by GMC-I Service GmbH.
Note
Prior to lengthy periods of rest (e. g. holiday), we recom-
mend removing the (rechargeable) batteries. This helps to
prevent excessive depletion or leakage of batteries,
which, under unfavourable circumstances, may cause
damage to the instrument.
10.3 Housing and Test Probes
No special maintenance is required. Keep outside surfaces clean
and dry. Use a slightly dampened cloth for cleaning. Avoid the use
of solvents, cleansers and abrasives.
Attention!
!
No condensation may be permitted to occur at the test
instrument, the test cables or the device under test,
because high-voltage may otherwise cause leakage cur-
rent at the surfaces. Insulated components may also
conduct high-voltage in this case.
Measurements may not be performed under moist ambient con-
ditions, where condensation has occurred or in explosive atmo-
spheres.
62 GMC-I Messtechnik GmbH
10.4 Measurement Cables
Inspect the measurement cables for mechanical damage at regu-
lar intervals.
Attention!
!
Even if only minimal damage is discovered at the test ca-
bles, it is advisable to send them immediately to GMC-I
Service GmbH.
10.5 High-Voltage Module Test Cables (Feature B1/B2)
Wind the test cables onto the provided cable uptakes at the back
of the trolley (feature D1) after each use if included. Test cables
may not, under any circumstances, be mechanically damaged or
kinked, because impaired insulation characteristics may other-
wise result.
Inspect the test cables and the high-voltage pistols for mechani-
cal damage before placing the high-voltage module into service
each time it is used.
Attention!
!
Even if only minimal damage is discovered at the test ca-
bles or high-voltage pistols, it is advisable to send them
immediately to the GMC-I Messtechnik GmbH Repair
and Replacement Parts service department.
10.6 Replacing Bulbs in the External Signal Lamps (Feature F1)
Attention!
!
Before replacing bulbs in the external signal lamps, dis-
connect them from the connector terminals at the test
instrument.
Ð Unscrew the red or green lens by turning it counterclockwise.
Ð Remove the defective bulb from the bayonet socket and insert
a new 12 to 15 V / 2 W bulb with BA9s base, e.g. OSRAM
miniwatt T10 no. 3453B.
Ð Screw the lens back into place by turning it clockwise.
10.7 Software
Internal test instrument software can be updated with the help of
a PC and an interface cable for the RS 232 interface. The soft-
ware is downloaded to the flash EPROM in the MERISO
PRIME+.
The data file with the desired software version is transmitted to
the test instrument via the serial interface with the help of the
update function included with WinProfi software. Previously
installed software is overwritten in the process.
Downloading Procedure
Ð Establish a connection between the PC and the
MERISO PRIME+.
Ð Switch the PC and the test instrument on.
Continue as described in chapter 3.7.5 on page 26.
GMC-I Messtechnik GmbH 63
Note
After updating the software, reinstall the desired lan-
guage to the test instrument as well, even if the language
will not be changed. This assures that all of the additional
functions included in the update are correctly displayed.
10.8 Recalibration
The respective measuring task and the stress to which your mea-
suring instrument is subjected affect the ageing of the compo-
nents and may result in deviations from the guaranteed accuracy.
If high measuring accuracy is required and the instrument is fre-
quently used in field applications, combined with transport stress
and great temperature fluctuations, we recommend a relatively
short calibration interval of 1 year. If your measuring instrument is
mainly used in the laboratory and indoors without being exposed
to any major climatic or mechanical stress, a calibration interval of
2-3 years is usually sufficient.
During recalibration* in an accredited calibration laboratory
(DIN EN ISO/IEC 17025) the deviations of your instrument in rela-
tion to traceable standards are measured and documented. The
deviations determined in the process are used for correction of
the readings during subsequent application.
We are pleased to perform DAkkS or factory calibrations for you in
our calibration laboratory. Please visit our website at
www.gossenmetrawatt.com (→ Company → DAkkS Calibration
Center or → FAQs → Calibration questions and answers).
By having your measuring instrument calibrated regularly, you ful-
fill the requirements of a quality management system per
DIN EN ISO 9001.
* Verification of specifications or adjustment services are not part of the calibration.
For products from our factory, however, any necessary adjustment is frequently
performed and the observance of the relevant specification is confirmed.
10.9 Device Return and Environmentally Compatible Disposal
The instrument is a category 9 product (monitoring and control
instrument) in accordance with ElektroG (German Electrical and
Electronic Device Law). This device is subject to the RoHS direc-
tive.
We identify our electrical and electronic devices in accor-
dance with WEEE 2012/19EU and ElektroG with the sym-
bol shown to the right per DIN EN 50419.
These devices may not be disposed of with the trash. Please con-
tact our service department regarding the return of old devices.
If you use batteries or rechargeable batteries in your instrument or
accessories which no longer function properly, they must be duly
disposed of in compliance with the applicable national regula-
tions.
Batteries or rechargeable batteries may contain harmful sub-
stances or heavy metal such as lead (PB), cadmium (CD) or mer-
cury (Hg).
They symbol shown to the right indicates that batteries or
rechargeable batteries may not be disposed of with the
trash, but must be delivered to collection points specially
provided for this purpose.
