LED flashlight. It is a necessary device for automobile manufacturing, and sales. evaluation, metal processing, painting, inspection, and other industries. It is widely used in manufacturing. metal processing, aeronautics and space, shipping, bullet trains, scientific research, quality supervision, and other fields.
The product is based on the principles of electromagnetic induction and eddy current measurement. The principle of electromagnetic induction measurement is to measure the coating thickness according to the size of the magnetic flux flowing from the sensor through the non-ferrous magnetic coating into the ferromagnetic matrix. The symbol is Fe. It can measure non-conductive or conductive coatings on magnetically permeable metals such as iron and steel (for example galvanized steel sheets). The principle of eddy current measurement is to measure the coating thickness according to the difference in the eddy current formed by an AC magnetic field on a non-magnetic metal matrix (such as aluminum). The symbol is NFL. It can measure non-conductive coatings on non-magnetic metal materials such as aluminum and copper. The matrix must be metal, and the coating cannot conduct electricity.

2. If the product has not been used for a long time or the operating environment has changed, a two-point calibration is required before use;
3. First, press the probe vertically on the object to be measured, and the value displayed on the LCD at this time is the estimated value of the coating thickness;
4. Refer to this estimated value, and select a standard coating thickness sheet closest to this value from the accessories to prepare for two-point calibration;
5. A matrix with the thickness of material close to the measured object and without coating should be selected as the calibration matrix as far as possible. When the above-mentioned matrix is not found, the standard matrix in the accessories can be selected as the calibration matrix (due to differences in material and thickness, the measurement results may be biased);
6. Please refer to the calibration chapter for the two-point calibration method;
7. After the two-point calibration is completed and verified repeatedly, the coating thickness of the object can be measured;
8. When measuring, select 3 to 5 measuring points on the surface of the measured object evenly, measure 5 times for each point, and take the average value of the 5 times as the indicating value of the point.
9. After the indicating values of the 3 to 5, measuring points are measured, the average of the values should be taken as the reference value of the object coating thickness.

Note

1. Hold the gauge perpendicular to the object to be measured, and lightly press the gauge sensor against the object surface for measurement. It is necessary to keep the sensor in close contact with the object’s surface.
