Electronic universal testing machine as the universal testing machine ismost frequently used, has attracted a lot of attention, due to improperoperation will people make error of electronic universal testing machine,electronic universal testing machine operation seemingly complex isrelatively simple, as long as the master the operation skills, flexible use,and in the process of use in careful detail, many errors can be avoided.Firstly, several error we must be familiar with electronic universal testing machine often appear, can better avoid error. At present, according to customer feedback and testing found that the error of electronicuniversal testing machine mainly has the following several:
Error one, electronic universal testing machine:
The experimental work of error, error caused by negligence. This erroris not regular, need each other to avoid repeated nuclear. Cause: theelectronic universal testing machine operation error, test personnelwrong number, record the location of the decimal point is wrong.
Two, the electronic universal testing machine system error:
Error keeps changing certain numerical or certain laws. System error is regular, the law embodied in every trial specific, find the law, can bemodified. The reason for this problem is to produce electronic universal testing machine has not shown: value 1, electronic universal testing machine, the measured force value is too large or too small. 2, the resistance strain gauge measuring strain, error coefficient on the instrument panel.
Three, the electronic universal testing machine random error:
Under the same conditions, the same parameter is repeated many timesmeasurement, the measured values can not be completely the same.Reasons: 1, in the course of the experiment, the change of internal friction test machine; 2, the change of environment humidity.
