Safety Precautions

1 Safety Features and Precautions

You have selected an instrument which provides you with a high

level of safety.

This instrument fulfills the requirements of applicable European

and national EC directives. This is confirmed by means of the

CE mark. A corresponding declaration of conformity can be

requested from GMC-I Messtechnik GmbH.

The TRMS digital multimeter has been manufactured and tested

in accordance with the following safety regulations:

IEC 61010–1:2010 / DIN EN 61010–1/VDE 0411–1:2011.

When used for its intended purpose (see page 10), safety of the

operator, as well as that of the instrument, is assured. Their safety

is however not guaranteed, if the instrument is used improperly or

handled carelessly.

In order to maintain flawless technical safety conditions, and to assure

safe use, it is imperative that you read the operating instructions

thoroughly and carefully before placing your instrument into service,

and that you follow all instructions contained therein.

The multimeter is equipped with an automatic socket blocking

mechanism for your safety, and in order to safeguard your

instrument. This mechanism is linked to the rotary switch and only

allows access to those jacks which are actually required for the

selected function. It also prevents the user from turning the rotary

switch to impermissible functions after the measurement cables

have already been plugged in.

Measuring Categories and their Significance per IEC 61010-1

The measuring category and the maximum rated voltage which

are printed on the device apply to your measuring instrument, for

example 1000 V CAT III.

For the application of measuring cables see page 66.

Observe the following safety precautions:

• The multimeter may not be used in potentially explosive

atmospheres.

• The multimeter may only be operated by persons who are ca-

pable of recognizing contact hazards and taking the appropriate

safety precautions. Contact hazards according to standard

exist anywhere, where voltages of greater than 33 V RMS or

70 V DC may occur. Avoid working alone when taking meas-

urements which involve contact hazards. Be certain that a sec-

ond person is present.

• Maximum allowable voltage between the voltage measuring

terminals, and between all connections and earth is 1000 V for

measuring category III, or 600 V for measuring category IV.

CAT Definition

Measurements in electrical circuits

which are not directly connected to the mains:

for example electrical systems in motor vehicles and aircraft, batteries etc.

Measurements in electrical circuits

which are electrically connected to the low-voltage mains:

with plugs, e.g. at home, in the office or laboratory etc.

III

Measurements in building installations:

stationary power consumers, distributor terminals, devices connected

permanently to the distributor

Measurements at power sources for low-voltage installations:

meters, mains terminals, primary overvoltage protection devices

GMC-I Messtechnik GmbH 9

Safety Precautions

• Be prepared for the occurrence of unexpected voltages at

devices under test (e.g. defective devices). For example,

capacitors may be dangerously charged.

• Make certain that the measurement cables are in flawless

condition, e.g. no damage to insulation, no interruptions in

cables or plugs etc.

• No measurements may be made with this instrument in

electrical circuits with corona discharge (high-voltage).

• Special care is required when measurements are made in HF

electrical circuits. Dangerous pulsating voltages may be

present.

• Measurements under moist ambient conditions are not

permitted.

• Be absolutely certain that the measuring ranges are not

overloaded beyond their allowable capacities. Limit values are

included in chapter 8, “Technical Data”, in the table entitled

“Measuring Functions and Measuring Ranges” in the “Over-

load Capacity” column.

• The multimeter may only be operated with installed batteries or

rechargeable batteries. Dangerous currents and voltages are

otherwise not indicated, and the instrument may be damaged.

• The instrument may not be operated if the fuse cover or the

battery compartment lid has been removed, or if its housing is

open.

• The input for the current measuring range is equipped with a

fuse link (exception: METRAHIT⏐B

ASE).

Maximum permissible voltage for the measuring circuit (= rated

voltage of the fuse) is 1000 V AC/DC.

Use specified fuses only (see page 59)! The fuse must have a

breaking capacity of at least 30 kA.

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 serv-

ice 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.

Repair and Parts Replacement

When the instrument is opened, voltage conducting parts may be

exposed. The instrument must be disconnected from the measur-

ing circuit before the performance of repairs or the replacement of

parts. If repair of a live open instrument is required, it 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 device demonstrates visible damage

• If the instrument no longer functions, or if malfunctioning

occurs

• After long periods of storage under unfavorable conditions,

e.g. humidity, dust or extreme temperature (see “Ambient Con-

ditions” on page 60)

10 GMC-I Messtechnik GmbH

Safety Precautions

1.1 Use for Intended Purpose

• The respective multimeter is a portable device which can be

held in the hand during the performance of measurements.

• Only those types of measurements described in chapter 5 may

be performed with the measuring instrument.

• The measuring instrument, including measurement cables and

plug-on test probes, may only be utilized within the specified

measuring category (see page 59 and the table on page 8

regarding significance).

• Overload limits may not be exceeded. See technical data on

page 54 for overload values and overload limits.

• Measurements may only be performed under the specified

ambient conditions. See page 60 regarding operating temper-

ature range and relative humidity.

• The measuring instrument may only be used in accordance

with the specified degree of protection (IP code) (see page 60).

1.2 Meanings of Danger Symbols

Warning concerning a point of danger

(attention: observe documentation!)

Warning concerning dangerous voltage at the measurement

input: U > 55 V AC or U > 70 V DC

1.3 Meanings of Acoustic Warning Signals

Voltage warning: > 1000 V (intermittent acoustic signal)

Current warning: > 10 A (intermittent acoustic signal)

Current warning: > 16 A (continuous acoustic signal)
