3.2.4 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 3-4):
1. Set the rotary switch to * range.
2. Press the SELECT key twice to activate Continuity Check.
3. Connect the black and red test leads to the COM and
respectively.
4. Connect the test leads to the resistance in the circuit being measured.
5. When the test lead to the circuit is below 40 , a continuous OFF beeping will
indicate it.
NOTE:
• Continuity test is available to check open/short of the circuit.

3.2.5 Capacitance measurement

To avoid electrical shock and/or damage to the instrument, disconnect
circuit power and discharge all high-voltage capacitors before measuring
capacitance. Use the dc voltage function to confirm that the capacitor is
discharged.
The Meter's capacitance ranges are 60.00nF, 600.0nF, 6.000µF, 60.00µF and
300.0µF.
To measure capacitance (set up the Meter as shown in Figure 3-5):
1. Set the rotary switch to * range.
2. Connect the black and red test leads to the COM and * terminals respectively
(or you can use capacitor test lead).
3. Connect the test leads to the capacitor being measured and read the
displayed value.
Some tips for measuring capacitance:
• The meter may take a few seconds (>30 seconds in 300.0uF range) to
stabilize reading. This is normal for high capacitance measuring.
• To improve the accuracy of measurements less than 60nF, subtract the
residual capacitance of the Meter and leads.
• Below 600pF, the accuracy of measurements is unspecified.
