5 reasons for the inaccurate measurement of the coating thickness gauge
(1) Strong magnetic field interference. We conducted a straightforward experiment and found that the measurement will be significantly tampered with when the device operates close to an electromagnetic field of about 10,000 V. It might experience the crash phenomenon if it is very near to the electromagnetic field.
(2) Human elements. The scenario frequently occurs to new users. The coating thickness gauge's ability to convert a small shift 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 if the user is unfamiliar with the instrument during measurement of the instrument. This will alter 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 master the measurement technique.The measurement is significantly impacted by the probe's location. The probe should remain parallel to the sample's surface throughout the reading. Additionally, the probe shouldn't be left in position for too long to avoid interfering with the matrix's magnetic field.
(3) During system testing, the wrong substrate was not chosen. The substrate must have a minimum width of 0.2mm and a minimum plane of 7mm. Measurements below this threshold are not accurate.
(4) The impact of any substances that are connected. The device is sensitive to substances that adhere and prohibit the probe from getting close to the overlay surface. To guarantee that the probe is in direct contact 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 when conducting system calibration.
(5) The tool malfunctions. You can now speak with experts or have the machine repaired at the factory.
Why do measurement data occasionally show glaring discrepancies during the measurement process?
The measurement data may be considerably larger as a result of the probe being positioned incorrectly or under the influence of outside interference factors. In order to prevent entering the data statistics at this point, you can hit and hold the CAL key to clear the data.
