This document describes the features and characteristics of the Extech CG204 coating thickness gauge, including measurement methods, display screen icon explanations, and quick start guide.
The Extech CG204 is a portable, non-intrusive instrument designed to measure coating thickness on ferromagnetic and non-ferromagnetic metal substrates. It utilizes two measurement methods: electromagnetic induction for ferrous metals and eddy current for non-ferrous metals. The device features a backlit LCD display with statistical analysis capabilities. This manual is written in Chinese.
The instrument automatically senses whether the substrate is ferromagnetic or non-ferromagnetic.
Users can select between microns (µm) and mils for measurements.
The instrument automatically shuts off after approximately 3 minutes of inactivity.
