When I measure with the BarScreenSensor, what do I have to pay attention to?

When measuring with the BarScreenSensor, it is important to remove the packaging of the object and apply the ultrasound gel to the measuring head. The measuring head must be in direct contact with the test piece.

It is also necessary to scan the entire ingot. It is possible that foreign metal inclusions can only be found at certain points within the object. In addition, the ingot should be physically measured beforehand so that the measured ultrasonic value can be compared with the real thickness.

Furthermore, it is important to pay attention to the size/thickness of the object. If it is too thin, the BarScreenSensor could give wrong results. Therefore, please use the BarScreenSensor only for bars of 50 grams or more. In addition, you should use at least one other measuring method (e.g. digital caliper and precision scale).

The smaller the bar to be tested, the more embossing and stamps in the gold/silver have an effect on the measurement result.
