testing diodes See Figure -6-
1. Set the Function Switch to Ω and press the SELECT button until � is displayed.
2. Connect the test leads: Red to +, Black to COM.
3. Turn off power to the circuit being measured.
4. Free at least one end of the diode from the circuit.
5. Connect the test probes across the diode noting polarity.
6. Read the display. A good diode has a forward voltage drop of about 0.6 V. An
open or reverse biased diode will read .0L.
Measuring Capacitance See Figure -7-
1. Set the Function Switch to Ω and press the SELECT button until � is displayed.
2. Connect the test leads: Red to +, Black to COM.
4. Turn off power to the circuit being measured.
5. Discharge the capacitor using a 100 kΩ resistor.
6. Free at least one end of the capacitor from the circuit.
7. Connect the test probes across the capacitor.
8. Read the display.
9. Relative zero 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).
