50Ω
Open Voltage: 0.5V
Overload protection: 250V DC/AC peak value.
Warning: Do not input the voltage at the range for safety.
Capacitance (C)
1.Turn the function/range selection knob to Capacitance Range.
Insert the red and black test lead separately to VΩHz 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.
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, it takes about 15 seconds at Range 100uF.
c) Cut the connection between the test lead and tested circuit at
