Frequently encountered problems and solutions in the use of coating thickness gauges
During the measurement process, why sometimes there are obvious deviations in the measurement data?
During the measurement process, due to the incorrect placement of the probe or the influence of external interference factors, the measurement data may be significantly larger. At this time, you can press and hold the CAL key to clear the data so as not to enter the data statistics.
3. How to calibrate the system?
The method and type of calibration are common problems for new users. System calibration, zero point calibration, and two-point calibration have actually been written in the manual, and users only need to read it carefully. It should be noted that when calibrating the iron base, it is best to measure several times to prevent wrong operations; the samples for system calibration should be carried out in order from small to large. If individual standard pieces are lost, you can find samples with similar values to replace them.
4. How to choose a suitable instrument model?
The best type of instrument to choose depends on the thickness of the object to be measured by the user. Generally speaking, when measuring objects below 1200um, it is best to choose MC-2000A type. For the thickness of 0~1200um, this model has reached 2%~3% accuracy, and it can also ensure the measurement accuracy for thickness values below 100um. If the thickness of the measured object is 1200~5000um, it is recommended to choose the MC-2000C thickness gauge. If it is thicker, choose the MC-2000D enhanced thickness gauge.
5. What is the reason for the interference when starting up sometimes?
After the instrument is turned on, the measurement status arrow appears on the screen of the instrument and the measurement cannot be performed again, which means that the instrument has been interfered. There are two main reasons:
(1) When starting up, the probe is too close to the iron base, which is interfered by the magnetic field of the iron base.
(2) The probe is not inserted properly or the probe line is damaged.
