7. Capacitance Measurement

1. Insert the red lead into “mA” terminal, and black lead into

“COM” terminal

2. Turn the knob to the Capacitance Range, then connect the

test leads across the tested capacitance (note the polarity
of the red lead is positive)

Note：

1. If the tested capacitor is unknown beforehand, should turn

the knob to the highest range,

2. and then turn to the relative range according to the value

displayed on LCD

3. If LCD displays “1”, it indicates overload, should turn the

knob to the higher range

4. Before measuring capacitor, it is possible the display on

LCD doesn’t return to zero, the reading on LCD will
gradually approach zero, please ignore it, it doesn’t affect
the accuracy of measurement.

5. When severe creepage or capacitor breakdown measured

at large capacitance range, LCD will display some value
unstably.

6. Before measuring capacitor, should completely discharge

the capacitor to avoid damaging the instrument.

7. 1uF =1000nF 1nF=1000pF

8. Frequency Measurement

1. Insert the leads or shield cable into “COM” and “V/Ω/Hz”

terminals.

2. Turn the knob to the Frequency Range, then connect the

test leads or cable across the signal source or tested load.

3. When input more 10Vrms, reading is available, but it is

possible to be out of specification.

4. In noisy environment, it is preferable to use shield cable

when measuring small signal

. Caution to avoid touching the high voltage circuit when
