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".
