Diode Test; Continuity Testing - Testboy TB-313 Instrucciones De Empleo

Operation

Diode test

With the selector switch set to "
'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 = an-
ode, 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 "
'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.
