Coating Thickness Gauge Common Faults and Troubleshooting
Coating thickness gauge is an essential testing instrument for controlling and ensuring products. It has the characteristics of small measurement error, high reliability, good stability, and easy operation, and is widely used in multiple fields. The coating thickness gauge may encounter certain malfunctions during use. Below, the editor will provide a detailed introduction to the common faults and troubleshooting methods of the coating thickness gauge, hoping to help everyone.
The displayed value is unstable.
The main reason for the unstable display of the coating thickness gauge is due to the special nature of the material and structure of the workpiece itself, such as whether the workpiece is a conductive magnetic material. If it is a conductive magnetic material, we need to choose a magnetic coating thickness gauge. If the workpiece is a conductive material, we need to choose an eddy current coating thickness gauge. The surface roughness and attachments of the workpiece are also the reasons for the temperature difference in the instrument display. The surface roughness of the workpiece is too large and there are too many surface attachments. The key to troubleshooting is to smooth out workpieces with high roughness, remove any attachments, and then choose a suitable coating thickness gauge.
There is too much error in the measurement results
We have already explained the reasons for the large measurement error of the coating thickness gauge in previous articles. Here, we will briefly introduce the main reasons for the large measurement error: substrate magnetization, substrate metal thickness too small, edge effect, workpiece curvature too small, surface roughness too large, magnetic field interference probe placement method, etc. New friends can refer to the article on the instrument to familiarize themselves, so we will not introduce them one by one.
Do not display numbers
The simple reason why the coating thickness gauge does not display numbers is to check if the battery is fully charged, and if it is found that the measurement still does not display values after confirming that the battery is fully charged.
