What are the factors that lead to inaccurate measurement of coating thickness gauge
What are the contributing elements to improper coating thickness measurement? A frequently used testing tool with the benefits of consistent performance, adaptability, and high dependability is the coating thickness gauge. What are the variables that contribute to the coating thickness gauge's incorrect measurement during usage? The coating thickness gauge will have the issue of inaccurate measurement during use. For everyone's convenience, Zhuhai Tianchuang Instrument Co., Ltd. summarizes the following:
(1) The coating thickness gauge's ability to transform minute variations in magnetic flux into digital signals 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.
(2) Strong magnetic field interference The measurement will be substantially thrown off if the instrument is used close to an electromagnetic field of 10,000 V or more. It might experience the crash phenomenon if it is very close to the electromagnetic 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 influence of attached substances. The instrument is sensitive to adhering substances that prevent the probe from making intimate contact with the overlay surface. Therefore, the attached substances must be removed to ensure that the probe is in direct contact with the surface of the covering layer. When performing system calibration, the surface of the selected substrate must also be bare and smooth.
(5) The instrument fails. At this time, you can communicate with technicians or return to the factory for repair.
