Resistance Measurement; Diode - TESTBOY TB-3000 Bedienungsanleitung

Operation

Resistance measurement

Set the selector switch to measurement range 'Ω'. Insert the black test lead
into the 'COM' socket and the red test lead into the 'V Ω A' socket. Using the
test probes, touch the test points of the test object. The multimeter
automatically searches for the most suitable measurement range. Read
measurement value on the display.

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.
