Three problems in the test of electronic universal testing machine

What problems will the electronic universal testing machine encounter during the test?

1. Electronic universal testing machine system error: keep a certain value or a certain regular error. There are two main reasons for this. One is that the universal test machine is not accurate. The measured force value is not too large or too small. Another reason is the error of the coefficient on the instrument panel when measuring the strain value by the resistance strain gauge. .

2. Random error of the electronic universal testing machine: that is, under the same conditions, the same parameter is repeatedly measured multiple times, and the obtained measured values â€‹â€‹are not completely the same. There are also two reasons for this error. During the test, the frictional force in the test machine may also change due to factors such as the ambient humidity of the test machine.

3, the final error will be the user's error, due to errors in the test work, negligence and other reasons caused by errors. This kind of error is irregular and needs to be repeated by the other party to avoid.
