3. Operation

3.1 Readying for use

• Insert battery into the battery

compartment. To do this open the

appropriate section of the housing

by pressing in the nub (7), e.g. us-

ing a screwdriver. Then insert the

battery and connected it to the

battery clip. Replace the section of

housing and snap it into place.

• Check the mechanical zero-point.

The measuring instrument may

not be connected to anything at

this time. The needle must be lo-

cated in the zero-point position

when the multimeter is in a hori-

zontal position. If necessary make

the corresponding adjustments by

means of the adjustment screw (6).

• Check the full scale deflection set-

ting for 0 Ω. To do this set the ro-

tary switch (1) to "x 1 Ω". Short-

circuit the connection sockets

A, Ω" (4). Set

50µA

"COM" (5) and "

100mV

the full scale deflection by turn-

ing the knob (2).

• If full scale deflection cannot be

set or the needle no longer stays

still, the battery must be replaced.

3.2 General instructions

• When performing measurements

always set the rotary switch (1) to

the highest measurement range.

Then turn to lower ranges until the

optimum needle deflection is ob-

tained.

• When the multimeter is not in use,

disconnect all measurement leads

from the meter, reset the rotary

switch (1) to the highest range and,

if necessary, remove the battery.

3.3 Voltage measurement

3.3.1 DC voltage up to 100 mV

_ +

COM

AΩ

• Set the rotary switch (1) to the

measurement range "50 µA,

100 mV".

• Connect the multimeter and take

a reading from the V, A DC scale.

3.3.2 DC voltage up to 600 V

_ +

COM

AΩ

• Using the rotary switch (1) select

the corresponding measurement

range "600,...,1 V DC".
