QINSUN Interpretation of Coating Thickness Gauge Troubleshooting-

Coating Thickness Gauge failures mainly include unstable indication, large error, and no value display. The causes of these failures come from the instrument itself and the part under test, as well as the influence of the natural environment. The following will introduce the methods to eliminate these failures.

1. The display is unstable

The cause of the unstable display of the coating thickness gauge mainly comes from the peculiarity of the material and the structure of the part itself, such as the workpiece itself Whether it is a magnetic material, if it is a magnetic material, we need to choose a magnetic coating thickness gauge, if the workpiece is a conductor, we need to choose an eddy current coating thickness gauge, and the surface roughness and attachments of the workpiece is also The reason why the instrument does not display any temperature isthat the surface roughness of the workpiece is too large, and there are too many surface attachments. The main point of troubleshooting is to polish the workpiece with a relatively large roughness to remove the accessory, and then choose a gauge of suitable coating thickness.

2. There are too many errors in the measurement results

The main reasons for large measurement errors are: base metal magnetization, metal thickness base is too small, the edge effect, the curvature of the workpiece is too small, and the surface is rough Too large, the magnetic field interference probe placement method, etc.

3. Doesn\'t show numbers

The simple reason the coating thickness gauge doesn\'t show numbers is to check if the battery is fully charged. .
