Open Voltage: 0.5V
Overload protection: 250V DC/AC peak value.
Warning: Do not input the voltage at the range for safety.
13. Capacitance (C)
1.
Turn the function/ range selection knob to Capacitance Range. Insert the red and black test lead
separately to V
Ω
Hz and COM input terminal.
2.
Connect the test lead to the tested capacitor in parallel, the tested capacitor value will be
displayed on LCD.
3.
If “OL” is displayed on LCD, it indicates the test capacitor value has exceeded the present range
limit or the capacitor is short-circuit, please select the higher range to complete the measurement.
4.
Read the present test result from LCD.
Note:
a.
When measuring the in-circuit capacitor, make sure all the power of the tested circuit has been
turned off and all capacitors are fully discharged ( Note: no Bar Graph display at this range)
b.
It requires longer testing time when measuring the large capacitor at once after measurement.

14. Frequency (Hz)
1.
Turn the function/range selection knob to Hz Range. Insert the red and black test lead separately
to V
Ω
Hz and COM input terminal.
2.
Connect the test lead to the tested signal source in parallel. (Note: no Bar Graph display at this
range)
3.
When measuring Frequency, press “Hz/DUTY” button to get into the mode of Frequency
measurement, and press “Hz/DUTY” button again to get into the mode of Duty Circlr measurement,
and press the button third to return to the mode of AC current ot voltage measurement.
Note:
a.
Do not input the signal more than 60V. Otherwise it is possible to damage the instrument and
endanger the safety of the users
b.
Cut the connection between the test lead and tested circuit at once after measurement.
