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:

1) Set the rotary switch to Ω

ΩΩ

Ω range.

2) Press the SELECT key twice to activate Continuity Check.

3) Connect the black and red test leads to the COM and Ω terminals respectively.

4) Connect the test leads to the resistance in the circuit being measured.

5) 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.

3.2.5 Capacitance measurement

To avoid electrical shock and/or damage to the instrume

nt, 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:

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 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.

3.2.6 Frequency and Duty Cycle measurement

Do not measure Frequency on high voltage (>1000V) to avoid e

lectrical shock

hazard and/or damage to the instrument.

The Meter can measure Frequency or Duty Cycle while making either an AC Voltage or AC Current

measurement.

To measure frequency or Duty Cycle:
