Diode test
With the selector switch set to "
into the 'COM' socket and the red test lead into the V/Ω/TEMP/CAP
socket. Using the test probes, touch the test points of the test
object. Red test lead = anode, black test lead = cathode. The
forward voltage drop is displayed.
Measurement
range
-Forward current: approx. 25 µA, reverse voltage: approx. 2.8 V.
Continuity testing
With the selector switch set to "
into the 'COM' socket and the red test lead into the V/Ω/TEMP/CAP
socket. Using the test probes, touch the test points of the test
circuit. An acoustic signal is emitted if a resistance under 70 Ω is
measured.
Important: Isolate from the power supply and discharge
capacitors in the circuit to be measured.
Measurement
range
-Measuring voltage: approx. 2.8 V.
