U17451 Analog Multimeter

Instruction sheet

10/04 MC/ALF

Handheld meter used to measure

current, voltage and resistance as

well as gain levels or attenuation e.g.

in chains of quadripoles.

1. Safety instructions

• Before using the analog multime-

ter, make sure you read the oper-

ating instructions carefully and

that you comply with them com-

pletely.

• The safety of the multimeter and

the person operating it can only

be guaranteed if it is used in ac-

cordance with the instructions. Do

not operate or handle this unit

incorrectly or inappropriately.

• The device may only be used by

persons, who are aware of the haz-

ards of contact (for voltages over

30 V rms) and can undertake the

appropriate safety precautions.

This also includes the appearance

of unforeseen voltages e.g. in de-

fective units or charged capacitors.

• In the case of voltage and current

measurements the nominal volt-

age between the phase and neu-

tral conductor may not exceed 300

V according to CAT II (in circuits

that are directly connected to the

mains) and CAT III (in building wir-

ing installations) 300 V.

• The analog multimeter may not be

used for measurements in circuits

with corona discharge (high volt-

age).

• In measurements involving RF cir-

cuits special care must be taken

due to the existence of dangerous

hybrid voltages.

• The appropriate permissible mea-

surement range may not be ex-

ceeded. Always change from a
