Diode Test; Continuity Test - Testboy TB 65 Manual De Instrucciones

Operation

Diode test

Set the selector switch to "
the "COM" jack and the red test lead to the "V/Ω" jack. Connect test
leads to the test specimen. Red test lead = anode, black test lead =
cathode. The forward voltage drop is displayed.

Continuity test

Set to " /
lead to the "COM" jack and the red test lead to the V/Ω/TEMP/CAP
jack. Connect test leads to the test circuit. A signal is emitted if a
resistance under 45 Ω is measured.
Important: Ensure isolation from the power supply
and discharge capacitors in the circuit to be
measured.
