The measuring ranges on the rotary switch correspond to the maximum
scale value. For the reading, always select the corresponding value (e.g.
scale 10 for the measuring ranges 10 and 100 (if you select 100 please
multiply the measured value by 10)).
a) Zero adjustment
Before each measurement, adjust the zero position with the calibration
screw (2) (scale value 0V). There must be no measuring signal on the
measuring lines.
b) Measuring AC and DC voltages
Do not exceed the maximum permitted input values;
this also applies when measuring superimposed direct
voltages (e.g. ripple voltages).
Proceed as follows to measure DC voltages:
- With the rotary switch, select the measuring
range V
.
- Connect the black measuring line to the
COM socket (5) and the red measuring line
to the V socket (7).
- Now perform the zero adjustment.
- Pay attention to the correct polarity (red = + /
black = -) and connect the two measuring
tips with the object to be measured (battery,
circuit, etc.).
- In the event of faulty polarity, no value will be
+
