1. Introduction The thickness gauge can non-destructively measure the thickness of non-conductive coatings on metal surface and the thickness of non-ferromagnetic coatings on ferromagnetic metal (such as iron, nickel and cobalt). Specific uses of the instrument include measuring the thickness of paint or galvanized layer on iron and stainless steel s surface, also, measuring the thickness of paint or plastic film on aluminum and ʼ...

calibration is not recommended after performing point calibration. (2) Clear Magnetic Clear zero calibration data of magnetic mode. (3) Clear Eddy Clear zero calibration data of eddy current mode. 5.7.3 Clear All Clear all calibration (including zero calibration and point calibration) data. 5.8 Batch (Car) Switch On the measurement page, short press the batch (car) switch button once and the batch (Car) number increases one to switch to the next batch (Car).

Using instrument normally, the error will be kept within certain indicators (refer to section 4). The user can make multiple measurements and delete the suspicious value at the same time, and finally use the statistical function of the instrument in order to measure the coating thickness more accurately.

For a more accurate measurement, it is recommended to carefully understand the factors that affect the measurement error before performing the measurement. The main influencing factors listed in the table are briefly described below: (1) Magnetic Properties of Substrate The thickness of the coating is measured by the principle of magnetic induction, which will be affected by the magnetic properties of the base metal.
finally the thickness of the coating can be measured by statistical methods. For the roughness of the substrate to be tested is relatively large, it can also be calibrated by multiple measurements during calibration. (5) Deformation of Substrate or Coating If the material of the base material or coating is soft, the probe may cause deformation of the base material or coating during the measurement, so the measured data will be unreliable.
measurement of the instrument is not exactly the same, so multiple measurements should be made in the adjacent measurement area. This is especially true for specimens with rough surfaces. In addition, when suspicious values are encountered, it is recommended to delete and then perform the next measurement. (3) Surface Cleaning Before measuring, ensure that the surface of the object to be measured and the surface of the instrument probe are clean.
