Repair, Parts Replacement and Balancing
When the instrument is opened, voltage conducting parts
may be exposed. The instrument must be disconnected from
the measuring circuit before the performance of repairs, the
replacement of parts, or balancing. If balancing, maintenance
or repair of a live open instrument is required, this may only
be carried out by trained personnel who are familiar with the
dangers involved.
Defects and Extraordinary Strains
If it may be assumed that the instrument can no longer be
operated safely, it must be removed from service and
secured against unintentional use.
Safe operation can no longer be relied upon,
• If the instrument or the test probes are damaged
• If the instrument no longer functions
• After long periods of storage under unfavorable
conditions (e.g. humidity, dust, or excessive
temperature), see „Ambient Conditions“, page 24.
2 Initial Start-Up
Storage Batteries or Batteries
Refer to chapter 14.1 regarding correct storage battery or
battery installation.
Warning!
The mains power battery charger may not be
connected if normal batteries (which are not suited for
recharging) have been inserted: Danger of explosion!
Attention!
!
As a result of internal voltage monitoring, the
instrument may respond as follows if the battery
charge level is low:
– Cannot be switched on
– Shuts back down immediately
– Shuts back down immediately when a load is
applied in the mΩ range
If this is the case, replace or recharge the storage
batteries.
Attention!
!
The mains power battery charger may only be used to
recharge the storage batteries!
Mains power battery chargers with an output voltage of
greater than 5 V may not be used. The milliohmmeter’s
internal voltage regulator might otherwise be destroyed.
No guarantee claims can be accepted if any mains
power battery charger other than the
NA HIT 2x
is used
(available as an accessory).
Switching the Instrument On Manually
Ð Press the ON|OFF key.
As long as the key is held depressed, all of the segments
at the LCD are illuminated. The LCD is shown on page 2.
Power-up is acknowledged with a brief acoustic signal.
The instrument is ready for use as soon as the key is released.
Switching the Instrument On with a PC
After transmission of a data frame from the PC, the
multimeter is switched on. See also chapter 12.6.
Switching the Instrument On Automatically
The multimeter is switched on automatically in the
transmission and memory modes.
Note!
Electrical discharge and high frequency interference
may cause incorrect displays to appear, and may
disable the measuring sequence. In such cases,
switch the instrument off and back on again in order
to reset. If the problem persists, briefly dislodge the
storage batteries from the connector contacts.
