Relevant precautions in the measurement of the coating thickness gauge
Before the measurement, it must be zero on the uncoated substrate with the same surface curvature radius, base material, thickness and measurement area as the sample to be tested, so as to ensure the accuracy of the measurement;
To ensure the accuracy of the reading;
the coating on the blasting and blasting surface can also be measured, but it should be rigorously calibrated according to the calibration procedure of the manual; do not force or fold the head line to avoid wire breakage; ,
alkaline solution or wet product, so as not to damage the probe;
the axis of the probe must be perpendicular to the surface to be tested when measuring;
each measurement should have a time interval of more than 3 seconds.
