4.
Switch off the power source and open the circuit to be tested at the
position you are going to measure the current.
5.
Turn on the current and touch the measuring points with the test tips.
6.
Once the reading stabilizes, read the value. If the polarity is reversed a
"Minus sign" is displayed.
Attention!
To avoid electric shocks, turn off the current of the device being tested and
unload all capacitors before performing the following measurements.
Resistance measurement
Set the rotary switch to the position
1.
2.
Attach the pin-plug of the black test lead to the COM-jack and the pin-plug
of the red test lead to the multi-function jack.
3.
Touch the measuring points with the probe tips.
4.
Once the reading stabilizes, read the value.
Diode test / Audible continuity
The device automatically distinguishes between audible continuity and diode
testing.
1.
Set the rotary switch to the position
2.
Attach the pin-plug of the black test lead to the COM-jack and the pin-plug
of the red test lead to the multi-function jack.
3.
Touch the measuring points with the probe tips.
Diode test:
The forward voltage shows 400 to 700mV. The counter voltage shows „OL".
Defective devices show a value about 0 mV or „OL" in both polarities.
