How To Use HT-670

How to make contact with the detector

To detect voltage correctly, make contact with the side of the tip to ensure a large contact area. If not, capacitance decreases and operating sensitivity becomes low.

Voltage detection for shield cable is not possible.

The voltage detector does not work because of the electrical shielding layer which is grounded.

Sensitivity adjustment

Sensitivity adjustment can be made when it is required for some reasons such as below.
①Detection is not possible over the outer surface of the insulated cable.
②It is required to reduce the influence of induced voltage of the area etc.
