Diode Tests
1. Connect the red test lead to the "VW " jack and the black test lead to the
"COM" jack.
2. Set the Function/Range switch to the "
3. Turn off power to the circuit under test.
4. Touch probes to the diode. A forward-voltage drop is about 0.6V (typical for
a silicon diode).
5. Reverse probes. If the diode is good, "OL" is displayed. If the diode is
shorted, ".000" or another number is displayed.
6. If the diode is open, "OL" is displayed in both directions.
7. If the junction is measured in a circuit and a low reading is obtained with both
lead connections, the junction may be shunted by a resistance of less than
1kW. In this case the diode must be disconnected from the circuit for
accurate testing.
Capacitance Measurements
1. Set the Function/Range switch to the desired capacitance range.
2. Never apply an external voltage to the

3. Insert the capacitor leads directly into the
4. Read the capacitance directly from the display.
