Method for avoiding errors in electronic universal testing machine

As the most commonly used universal testing machine, the electronic universal testing machine has also attracted everyone's attention. Due to improper operation, the electronic universal testing machine error will appear. The operation of the electronic universal testing machine seems complicated, as long as it is simple. Familiar with operational skills, flexible use, and careful and meticulous in use, many errors can be avoided. First of all, we must first familiarize with several errors that often occur in electronic universal testing machines, in order to better avoid the occurrence of errors. At present, according to customer feedback and testing, the errors of the electronic universal testing machine are mainly as follows:

 First, the error of the electronic universal testing machine: 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. Cause: The electronic electronic universal testing machine is operating incorrectly. The tester misreads the number and writes the wrong decimal point position.
     

Second, the electronic universal testing machine system error: maintain a certain value or a certain regular variation of the error. The systematic error is regular. This kind of law is reflected in every specific experiment. Once this law is found, it can be corrected. The reasons for this kind of problem caused by the electronic universal testing machine are as follows: 1. The value of the electronic universal testing machine is not accurate, and the measured force value is always too large or too small. 2. The error of the coefficient on the instrument panel when measuring the strain by the resistance strain gauge.

 Third, the electronic universal testing machine random error: that is, under the same conditions, repeated measurements on the same parameter, the measured values can not be identical. Causes: 1. During the test, the friction inside the test machine changes; 2. Changes in ambient humidity, etc.
