Take the CHY-C2A thin film thickness gauge as an example. The thin film thickness gauge adopts the mechanical contact measurement method, which strictly meets the requirements of the standard, and effectively ensures the standardization and accuracy of the test. It is suitable for accurate thickness measurement of various materials such as plastic films, thin sheets, separators, paper, foils, silicon wafers, etc.
Preparation
1. Check the equipment: Make sure that the thickness gauge CHY-C2A has sufficient power or has been properly connected to the power supply, check whether the appearance is intact and whether the display screen is clearly visible.
2. Choose the right probe: choose the right probe according to the type and characteristics of the material to be measured. The contact area of the measuring head of the film material is 50mm2 according to the relevant test standards; On the other hand, the contact surface of the measuring head for measuring the thickness of the paper is 200mm2.
3. Sample preparation: The surface of the sample to be measured should be flat and free of dirt, grease, oxide layer or other impurities that may affect the measurement accuracy, so as to ensure that the surface is dry and free of residues.
Thickness measurement
1. Place the sample: spread the sample to be measured flat on the measuring table to keep the sample neat, clean, flat and wrinkle-free. Multi-point thickness measurement can be performed by manually moving the specimen.
2. Test principle: The thin film thickness gauge adopts the mechanical contact test method, which is to test the thickness of the film material through the displacement sensor.
3. Measurement: Before the test, the measuring head of the instrument falls on the cutting board of the equipment, the sensor reads the initial displacement value of the measuring head, after the measuring head is lifted, the sample is placed on the cutting board paper, the measuring head falls on the sample with the same pressure, the sensor reads the displacement value of the measuring head, and the difference between the two displacement values is the thickness value of the sample.
4. Reading result: After the measurement is completed, the measured thickness value will be displayed on the display screen of the thickness gauge. Document the measurement results, including the location, date and time of the measurement point, as well as any factors that may affect the accuracy of the measurement.
Precautions
1. Keep the machine clean: During non-test time, it is necessary to cover the whole machine with a dustproof cloth to keep the machine and the surrounding environment clean.
2. Correct operation: The operator should operate on the basis of being familiar with the equipment manual and the principle of electrical appliances, and it is strictly forbidden to disassemble the machine without authorization.
3. Avoid interference: When measuring, ensure that there is no electromagnetic magnetic field around the instrument to interfere with the work.
4. Repeated measurement: In order to improve the accuracy and reliability of the measurement, it is recommended to repeat the measurement several times in the same location or multiple locations, and take the average value as the final result.
By following the above steps and precautions, you can ensure the correct use of the thin film thickness gauge CHY-C2A and the accuracy of the measurement results.
