4.5 AC Current Measurement

1） Hold the trigger, open the clamp head and clamp one cable of the measured
circuit.
2） When measured signal >0.05A, the main LCD of the meter displays the
measured current value, the vice LCD displays current frequency (Note: When
the frequency ＞300Hz, only when current value >0.2A could the meter
displays its frequency value)
3） When measured circuit,
the meter displays the maximum current value captured.
