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.

Capacitance is the ability of a component to store an

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 µ
F,
40.00 µ F and 200.0 µ
F.

¥ The meter may take a few seconds (200 µ 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.
