DC current measurement ( DC)
(Alternating current measurements are not possible.)
1.
Set the rotary switch to the position A=
2.
Switch off the power source and open the circuit to be tested at the
position you are going to measure the current.
3.
Turn on the current and touch the measuring points with the test tips.
4.
Once the reading stabilizes, read the value. If the polarity is reversed a
"Minus sign" is displayed.
Resistance measurement
Before making any measurements, make sure the circuit is disconnected from
any power source and all capacitors are properly discharged!
Set the rotary switch to the position
1.
2.
Touch the measuring points with the probe tips.
3.
Once the reading stabilizes, read the value.
Diode test / Audible continuity
Before making any measurements, make sure the circuit is disconnected from
any power source and all capacitors are properly discharged!
The device automatically distinguishes between audible continuity and diode
testing.
1.
Set the rotary switch to the position
2.
Touch the measuring points with the probe tips.
Diode test:
3.
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.
Audible continuity:
3.
If there is a resistor < 30 Ω, you hear a beep. When the circuit is open, the
display shows "OL".
