Reasons for Measurement Inaccuracy Findings from the Coating Thickness Gauge
1. Strong magnetic field interference The measurement will be severely distorted if the equipment operates close to powerful electromagnetic fields. It might experience the crash phenomenon if it is very close to the electromagnetic field.
2. Human variables. If the user is unfamiliar with the thickness gauge, the probe may stray from the object being tested during the measurement process, changing the magnetic flux and leading to an inaccurate reading. As a result, be careful to learn the measuring technique before using this instrument for the first time. The measurement is significantly impacted by the probe's positioning. The probe should remain parallel to the sample's surface throughout the measurement. Additionally, the probe shouldn't be left in position for too long to avoid interfering with the matrix's magnetic field.
3. Failing to choose an appropriate substrate for system rectification. The substrate must have a minimum thickness of 0.2mm and a minimum plane of 7mm. Measurements below this threshold are not accurate.
4. The impact of drugs that are linked. In order to ensure that the probe is in direct contact with the coating surface, adhering materials must be removed because they can affect how sensitively coating thickness gauges measure coating thickness when they are present. The surface of the chosen substrate must also be bare and smooth before systematic adjustment can be carried out.
5. The device malfunctions. Repair by professionals or go back to the factory for repairs.
