3.2.5 Continuity Check

To avoid electrical shock and/or damage to the instrument, disconnect circuit
power and discharge all high-voltage capacitors before testing for Continuity.
To test for continuity (set up the Meter as shown in Figure 3-6):
1. Set the rotary switch to
2. Connect the black and red test leads to the COM and Ω terminals
respectively.
3. Connect the test leads to the resistance in the circuit being measured.
4. When the test lead to the circuit is below 50Ω, a continuous beeping will
indicate it.
NOTE:
Continuity test is available to check open/short of the circuit.

3.2.6 Diode Test

To avoid electrical shock and/or damage to the instrument, disconnect circuit
power and discharge all high-voltage capacitors before testing diodes.
To test a diode out of a circuit (set up the Meter as shown in Figure 3-7):
1. Set the rotary switch to
2. Press the FUNC. key to select Diode Test.
3. Connect the black and red test leads to the COM and Ω terminals
respectively.
4. For forward-bias readings on any semiconductor component, place the
red test lead on the component's anode and place the black test lead on
the component's cathode.
5. The meter will show the approx. forward voltage of the diode.
In a circuit, a good diode (Si) should still produce a forward bias reading of
0.5V to 0.8V; however, the reverse-bias reading can vary depending on the
resistance of other pathways between the probe tips.
