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.
Continuity is a complete path for current flow.
The beeper sounds if a circuit is complete. These brief
contacts cause the Meter to emit a short beep.
To test for continuity:
1. Set the rotary switch to range.
2. Press the / key 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 50 Ω , 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
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.
Capacitance is the ability of a component to store an
electrical charge.

The unit of capacitance is the farad (F). Most capacitors are
in the nanofarad to microfarad range. The Meter measures
capacitance by charging the capacitor with a known current
for a known period of time, measuring the resulting voltage,
then calculating the capacitance. The measurement takes
about 1 second per range.
The Meter's capacitance ranges are 4.000nF 40.00nF,
400.0nF, 4.000

To measure capacitance:
1. Set the rotary switch to
Cap range.
2. Connect the black and red test leads to the
COM
and
Cx
terminals respectively.
3. Connect the test leads to the capacitor being measured
and read the displayed value.
Some tips for measuring capacitance:
Ω
The meter may take a few seconds (200 F range, 30
seconds) to stabilize reading. This is normal for high
capacitance measuring.
To improve the accuracy of measurements less than 4nF,
subtract the residual capacitance of the Meter and leads.
3.2.6 Frequency measurement
Do not measure Frequency on high voltage
(>250V) to avoid electrical shock hazard and/or
damage to the instrument.
1. Set the rotary switch to
Hz
range.
2. Connect the black and red test leads to the COM and Hz
terminals respectively.
3. Connect the test leads across the source or load under
measurement, and read the displayed value.
Note:
Ω In noisy environment, it is preferable to use shield cable for
measuring small signal.
