Diode; Continuity Test - TESTBOY TB-3000 Bedienungsanleitung

Operation

Diode

Set the selector switch to measurement range 'Ω'. Insert the black test lead
into the 'COM' socket and the red test lead into the right-hand socket. Use
the 'M' button to set the device to
points of the test object. Red test lead = anode, Black test lead = cathode.
The forward voltage drop is displayed.

Range
Forward biasing current: approx. 0.6 mA, backward voltage: approx. 1.5 V.
Over-range protection: 600 V AC / DC < 30 s.

Continuity test

Set the selector switch to measurement range 'Ω'. Insert the black test lead
into the 'COM' socket and the red test lead into the right-hand socket. Using
the button 'M', set the device to '◦))'. Using the test probes, touch the test
points of the test circuit. An acoustic signal is emitted if resistance below
50 Ω is measured. Read measurement value on the display.
Isolate from the power supply and discharge capacitors in the circuit
to be measured.
