B. Working Principle

The Metrix Plus CD 3 works using non contact voltage detection technology.

An energized AC conductor generates an alternating electric field around it. When the sensing tip of the CD 3 is brought near the conductor, its capacitive sensing circuit detects this electric field without requiring direct electrical contact with the conductor.

When AC voltage is detected, the instrument alerts the user through its bar graph and beep indication.

The selectable sensitivity allows the user to choose between:

High Sensitivity: 12V to 1000V AC

Low Sensitivity: 48V to 1000V AC

This can help technicians distinguish between different voltage detection requirements and reduce unwanted detection in certain applications.
