Resistance Measurement / Ω; Diode Test; Continuity Testing - TESTBOY TB 313 Bedienungsanleitung

Operation
Discharge the capacitors before every measurement.
Resistance measurement / Ω
Use the selector switch to set the appropriate range. Insert the black test lead 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. Read measurement value on the display.

Diode test

With the selector switch set to "
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 dis-
played.
Measurement range
- Forward current: approx. 25 µA, reverse voltage: approx. 2.8 V.

Continuity testing

With the selector switch set to "
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.
