Leakage Current/Current/Voltage Measurement
High voltage, very dangerous
！
Only qualified personnel
after training could conduct operation on it. The operator
should obey safety regulations; Otherwise there will be the
danger of electric shock resulting in personal injury or
casualty.
Dangerous! Can not be used to test voltage higher than
600V. Otherwise there will be the danger of electric shock
resulting in personal injury or casualty.
Make sure the clamp well closed when measuring leakage
current and current.
Make sure the measured wire at approximately the
geometric center of the clamp.
Clean the clamp after finishing measurement, regularly
maintain the meter.
Be sure to connect test wires correctly when measuring
voltage to avoid short circuit.
After measuring voltage, should firstly take the test line
away from measured wire, and then draw from meter, in
order to avoid shock.
Clamp live wire and null line together to measure leakage
current of electric equipment. (Note: 2 wires)
Clamp earth wire to measure grounding line leakage
current of electric equipment. (Note: single wire)
Clamp four wires of there phase to measure the total
leakage current. ( Note: 4 wires)
Clamp main line to measure total current of that main line.
(Note: single wire)
