 A, mA, and A Current functions
Default at DC . Press SELECT button momentarily to select AC.
Discharge capacitors before making any measurement. Large value
capacitors should be discharged through an appropriate
resistance load .

Defaults at  . Press SELECT button momentarily 2 times to select
Diode test function. Normal forward voltage drop (forward
biased) for a good silicon diode is between 0.400V to 0.900V. A
reading higher than that indicates a leaky diode (defective). A zero
reading indicates a shorted diode (defective). An OL indicates an
open diode (defective). Reverse the test leads connections
(reverse biased) across the diode. The digital display shows OL if
the diode is good. Any other readings indicate the diode is
resistive or shorted (defective).
Diode Test, Capacitance Function
Defaults at  . Press SELECT button momentarily 3 times to select
Capacitance function. Relative zero Δ mode can be used to zero
out the parasitic capacitance of the leads and the internal protection
circuitry of the meter when measuring low capacitance in the order
of Pico Farad (pF).
