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's capacitance ranges are 20.00nF, 200.0nF,
2.000
μ
F, and 20.00
μ
F.
To measure capacitance:
1. Set the rotary switch to proper range.
2. Connect the black and red test leads to the COM and
terminals respectively (or you can measure the
capacitance by using the special Multi-Function Socket).
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 20nF,
subtract the residual capacitance of the Meter and leads.

3.2.6 Transistor measurement
To avoid electrical shock and/or damage to the
instrument, do not apply more than 250Vdc or
250Vac rms between the hFE terminal and the
COM terminal.
1. Set the rotary switch to
hFE range.
2. Connect the “com” plug and “+” plug of the special
multi-function socket to the
COM and hFE terminals.
3. Determine whether the transistor to be tested is NPN or
PNP type and locate the Emitter, Base and Collector leads.
4. Insert leads of the transistor into proper holes of the
special multi-function socket.
5. The meter will show the approx. hFE value at test
condition of base current 10
μ
A and Vce 2.8V.
3.2.7 Frequency measurement
Do not measure Frequency on high voltage
(>380V) to avoid electrical shock hazard and/or
damage to the instrument.
Frequency is the number of cycles a voltage or current
signal completes each second.
To measure frequency:
1. Set the rotary switch to 20kHz range.
2. Connect the black and red test leads to the COM and
Hz terminals respectively.
3. Connect the test leads to the circuit being measured
4. Read the displayed value.
