600V CLAMP METER
NON-CONTACT (NCV) AC ELECTRIC FIELD SENSING
The electric field sensing sensitivity is divided into two levels (“EFHI” and “EFLo”).
The meter defaults to “EFHI”/ Users can select different sensitivity levels according to the
intensity of the measured electric field.
1. Select
NCV
on the function selector. Display will show “EFHI”.
2. Hold sensing end close to a charged electric field (socket, insulated wire, etc.).
The LCD will display “-“ with beeps and a red LED flashing.
3. As the intensity of the measured electric field increases, more segments (----) display, the
buzzer beeps quicker and LED flashes faster.
4. If the electric field is around 110 V AC 50Hz/60Hz, press the Select button to enter “EFLo”
mode.
NOTE:
•
When using this function, in order to avoid the
COM
input interference, which will affect
the electric field and the accuracy, please pull the black test lead out of the
COM
input.
