Diode Check:
1. Turn off power to the device or circuit that is being tested
and discharge all capacitors.
2. Plug the Black test lead into the COM port and the Red
test lead into the VΩHz port.
3. Set the rotary switch to the Ω position.
4. Press the blue button until is shown on the display
5. Connect the test leads to the diode. Normally the forward
voltage drop of a good silicone diode is shown between
400V and 0.9V. If the diode under test is defective, “000”
(short circuit) or “OL” (non-conductive) is displayed.

To Measure Capacitance:
1. Turn the power off to the circuit or device that is to be measured
and discharge all capacitors before attempting a measurement.
2. Plug the Black test lead into the COM port and the Red test lead
into the VΩHz port.
3. Set the rotary switch to the position.
4. Connect the leads to the circuit to be measured.
5. Measure Capacitance
In order to ensure the best accuracy in measurement of low capacitance,
open the test leads before measurement and
memorize the test probe capacitance. It is necessary to
subtract the capacitance of the test probes themselves, or use the rela-
tive mode to compensate for the test leads.
