Digital Clamp Meter Basics and Features

This page provides an overview of digital clamp meters, highlighting its benefits. It mentions features of Digital Clamp Meter from MECO and explores differences between analog and digital clamp meters.

Definition:

A clamp meter is a device used to measure current and voltage by clamping its jaws around a conductor. There are two main types: analog and digital. Analog clamp meters use a pointer indicator, while digital clamp meters use a numeric display.

AC current measurement in clamp meters relies on the coupling effect, similar to how a transformer works. DC current measurement utilizes Hall effect sensors.
