A number of factors contribute to erroneous coating thickness gauge measurements.
The following factors are the main causes of erroneous measurements for coating thickness gauges.
(1) Strong magnetic field interference We conducted a straightforward experiment and found that the measurement will be significantly tampered with when the equipment operates close to an electromagnetic field of roughly 10,000 V. It might experience the crash phenomenon if it is very close to the electromagnetic field.
(2) Human elements. The situation frequently occurs to new users. The coating thickness gauge's ability to transform a slight change in magnetic flux into a digital signal allows it to measure coating thickness down to the micron level. The probe may stray from the body being tested during the measuring procedure if the user is unfamiliar with the instrument. This will modify the magnetic flux and result in an incorrect measurement. Therefore, when using the instrument for the first time, it is advised that users and friends first grasp the measurement procedure.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) During system calibration, the wrong substrate was not chosen. 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 any compounds that are linked. The device is sensitive to chemicals that adhere and prevent the probe from getting close to the overlay surface. To guarantee that the probe is in direct touch with the surface of the covering layer, the attached materials must be taken out. Additionally, the surface of the chosen substrate must be bare and smooth for performing system calibration.
(5) The tool malfunctions. You can now speak with professionals or have the machine repaired at the factory.
Why do measurement results occasionally show glaring variances during the measurement process?
The measurement data may be much greater as a result of the probe being positioned incorrectly or under the effect of outside interference sources. In order to prevent entering the data statistics at this point, you can press and hold the CAL key to clear the data.
