COATING THICKNESS GAUGE CM-205FN
Introductions: The thickness gauge is used to measure the thickness of the plated and coated sheet on metal, e.g. paint/enamel/ chrome on steel, paint and anodizing coating on aluminum/copper. The gauge takes the precision integrated probe, and uses principles of electro-magnetic induction and the eddy current effect, which automatically detects the attribute of substrates. Application Field: The Gauge is designed for non-destructively measuring the thickness of coating and painting.
Operating Principle: The gauge adopts the principle of electromagnetic induction and eddy current effect. It has F probe and N probe. F probe works on the magnetic induction principle and should be used for detecting the non-magnetic coating’s thickness such as chrome/copper/zinc/varnish/rubber on the iron/steel substrate. N probe works on the eddy current principle and should be used for detecting the insulating coating’s thickness such as paint/anodizing/ceramics on the aluminum/copper/brass substrate.

Note: The final specifications may be upgraded without notifying. For more details, Please consult with your supplier. Factors of Affecting Accuracy User needs to know the factors of affecting measurement accuracy before using the gauge. The factors are listed as below: Curvature radius convex <1.5mm Curvature radius concave <25mm Diameter of measuring area <6mm Thickness of substrate <0.
1. Placing the Battery: Open the battery compartment and insert 2*AAA batteries, Close the lip 2. Prepare the target samples for measuring. 3. Placing the gauge in the air, at least 5cm away from any mental, then power on, wait for 5 seconds for system initialization. Note: Please upgrade batteries, if the LCD shows low battery which will lead to the measurement unreliable. 4.
Measurement Modes “SNG”: the Single Mode (Default), Press "MODE" key to display SNG, Vertically and rapidly placing the probe on the sample. The readings display on LCD with one beeping.
directly placing the probe on the sample. The readings will continuously upgrade following with the probe moving, as showing below: Description of “Fe” and “NF” “Fe” in LCD means: Target substrate is ferrous material such as iron/steel. “NF” in LCD means: Target substrate is non-ferrous material such as aluminum/copper.
Unit Switching Press “um/mil” key to switch unit “um” or “mil” Auto Power Off Automatically power off without any operations within 5min. System Reset: Press and hold "MODE/RESET" key until the full screen displays with two beeping, the system resetting is successful. Note: system resetting is mainly used for the return of error operation and error calibration. Calibration: Calibration adjustment is the process of setting the gauge to be more accurate.
use your target bare metal substrate instead of our attached substrates. Note: Once you did a misoperation, please press and hold “MODE/RESET”KEY 3 seconds for resetting the factory default.
Other Points Calibration: In the SNG mode (the screen displays “SNG”), the thickness sheet (5 sheets of 50/100/250/500/1000) is placed on the iron-substrate, aluminum-substrate or uncoated bare metal substrate.
then press “CALIB/ZERO” key again back normal mode to save the data, then measure it and check the calibration result. Repeat the above steps.
hyperthermia, humidity, strong magnetic field. If the gauge is no response and can’t be power on, please remove the battery, and wait for minutes, then reinstall the battery for try again. If the error still persists, please contact with your supplier for help.
