AC and DC Voltage Measurement

1. Connect the red probe to the "V/Ω/
the black probe to the COM input (6) an.
2. Set the rotary function switch (4) to a corresponding position
for AC/DC voltage measuring (V~ or V ). In the display (1)
"000" is displayed.
3. Now connect the probes to the circuitry or the component you
intend to measure. When measuring DC voltage, observe
correct polarity, if possible (Red to Plus and Black to Minus).
4. Now the result can be read from the LC display. If a negative
result is measured, a minus symbol is displayed to the left of
the result. If necessary, correct the polarity by changing the
probes on the circuit or on the component.
Hints
While the unit is idle (no measuring subject connected) with
the probes plugged in, the value in the display may constantly
shift. This is caused by the high sensitivity of the multimeter.
When a measuring subject is connected, the value in the
display corresponds exactly to the accuracy stated in the
technical data.
The unit has an input resistance of 10 MΩ in all voltage
measuring ranges.
If the measuring range is exceeded the overload symbol "1"
will be displayed.

AC and DC Current Measurement

Important Notice!
The maximum current which can be measured without
damage to the unit is 10 A. Do not connect any power source
directly to the power measuring sockets of the unit (except of
a battery voltage test "BATT1.5V"). Make sure you do not
attempt to measure currents of over 10 ampere and terminate
a measuring of high currents after a maximum of 10 seconds.
