7.9 Diode Test:
WARNING!
Do not apply voltage or current to the meter when it is set
to the Diode Test / Continuity Beeper “ ” range
7.9.1 Connect the black test lead to the COM jack and the red test
lead to the VOLT / DIODE / OHM / CAP “V Ω CAP” jack.
7.9.2 Set the RANGE switch to the Diode Test / Continuity Beeper
“ ” range.
7.9.3 Connect the test probes to the device or circuit to be tested.
To test a simple diode, connect the red test probe to the Anode
of the diode and the black test lead to the Cathode (“banded”
end) of the diode. The LCD will indicate the voltage drop of the
diode. Reverse the connections of the test probes to the diode.
The LCD should indicate overrange (“1 - - -”). If the Continuity
Beeper sounds when the leads are connected in either direction
to a standard silicon diode, the diode is probably shorted.
Note: The reading displayed on the LCD is an accurate indication of the
voltage drop of the device or circuit being measured.
