Coating Thickness Gauge FAQs
Question: Why does the coating thickness gauge turn on abnormally and alarm?
Answer: During the use of the coating thickness gauge, sometimes an alarm will occur when it is turned on. Generally, there are the following reasons:
1. If you turn on the instrument without inserting the probe, an instrument failure alarm will appear after turning on the instrument. This is a normal alarm. You must turn off the instrument, insert the probe and then turn it on again.
2. If the required fault alarm occurs after the probe is inserted and turned on, first shut down and re-insert the probe to check whether the probe is not inserted properly, causing poor contact and causing an alarm.
3. If the probe is indeed plugged in, but the alarm still sounds after powering on, it may be that the probe connection cable was loosened when plugging or unplugging the probe, or the probe itself is damaged. Please send it back to the after-sales department for inspection and repair. Do not dismantle or repair it yourself to avoid further damage.
4. If there is no response when pressing the keyboard after turning on the computer, under the guidance of after-sales personnel, open the back cover and reconnect the loose connection cable. If the keyboard fails due to prolonged use, send it back for replacement.
Q: What is the reason for the deviation in the measurement value at the same point?
Answer: If the measurement value of the same point of the coating thickness gauge deviates during use, there are several problems that need to be solved:
1. If you want to test the deviation of the measurement value at the same point, you can set the instrument under continuous measurement conditions and place it on the surface to be measured without moving. The instrument will automatically measure continuously and give continuous measurement values. You can automatically determine the deviation of the measurement value at the same point and the quality of the instrument. Do not manually measure continuously at the same point, because you cannot place it exactly at the same point, and the measured value cannot be a deviation from the same point.
2. During measurement, the measurement values vary greatly within a small area. Generally, it is caused by the surface roughness and unevenness of your substrate, which is a normal phenomenon. If there is no difference in the measured values at this time, it must be wrong!
3. If the phenomenon in 2 occurs, the customer can take multiple measurements and then obtain the average value from the instrument, that is, look at the average thickness.
4. The instrument itself has a calibration base made of No. 45 steel. When using it, the user should calibrate the zero point on the same material as the measured object without coating. If the measured object has a curvature, the calibrated zero point should have the same radian or the same shape.
