The functions of ST100 are more comprehensive, ST100 can measure DC/AC voltage, Resistance, Capacitance, Frequency, Phase Sequence, Live Wire, Diode and Continue.
1)Press the power key to power on into NCV measurement mode by default.
2)Gradually close the NCV sensing area to the measured conductor.
When the weak electric field signal is detected, it will display '---L'; the buzzer will sound slowly and the green light on.
When the strong electric field signal is detected, it will display '---H'; the buzzer will sound quickly and the red light on.
Non-contact measurement, more secure.
You can see more clearly on this screen.
The buzzer will give a quick warning when the end of the tester is close to the object being measured.
