Diode Continuity Tests
Press
to select diode continuity function, then connect the test leads
across the diode under test as shown in Figure 2-7 (Reversing the polarity
will reverse-bias the diode).
The diode test measures the forward voltage of a semiconductor junction
at approximately 0.5mA. The beeper generates a single beep tone when
the input voltage drops below +0.7V (approximately 1.4k
Ω
) and generates
a continuous beep tone when the input voltage drops below +50mV
(approximately 100
Ω
).
Readings are displayed in the 2.3V range. “
OL
” is displayed for voltage
above 2.3V. If the diode continuity test is performed, readings are
displayed in 0.1mV resolution on the 2.3000V range.

WARNING!
To avoid damaging to the meter, do not apply a voltage
exceeding 500 V peak between the input terminals.
