When measuring DC voltage, the meter shows the polarity with the
red test lead
Voltage measurements below DC 200 mV and AC 500
mV may be inaccurate or indicate errors
Never perform the meas
-
urement of current if open circuit voltage to earth exceeds 600 V.
AC/DC amperage measurement
1. Connect the red testing cable to
a ma
socket
, and the black cable to
COM
socket
.
2. Hold down the
button for min. 1 s to turn on the meter. The display
will show "- - - -".
3. Open the circuit, in which amperage will be measured and attach gauging
cables to the gauged circuit.
4. Read amperage value from the display

Prior to resistance measurement the circuit’s power supply must be
switched off and all capacitors discharged
For resistance meas-
urements > 10 M
, the meter needs a few seconds to display the
correct result.
Diode test
1. Connect the red testing cable to
INPUT
socket
, and the black cable to
COM
socket
.
2. Hold down the
button for min. 1 s to turn on the meter. The display
will show "- - - -".
3. Press the
button
to select
measurement function
.
4. Attach the red gauging cable to anode and black cable to cathode of gauged
diode.
5. Read diode’s conducting voltage on display
. By reversed cables a “OL”
shall be displayed.
Maximum open circuit voltage: 1.5 V
Overload protection: 250 V
