Diode; Continuity Test - Testboy TB-3000 Instrucciones De Empleo

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.
