How to avoid errors in electronic universal testing machines

Electronic universal testing machineAs a commonly used universal testing machine, it has also attracted much attention from everyone. Due to improper operation of people, errors in electronic universal testing machine will occur. The operation of electronic universal testing machine seems complicated and is actually relatively simple. As long as you master the operating skills, use them flexibly, and be more careful during use, many errors can be avoided. First of all, we must first be familiar with the several errors that often occur in electronic universal testing machines in order to better avoid the occurrence of errors. At present, based on customer feedback and testing, it is found that the errors of electronic universal testing machines are mainly as follows:

Electronic universal testing machine as the universal testing machine is most frequently used, has attracted a lot of attention, due to improve operation will people make error of electronic universal testing machine,electronic universal testing machine operation seems 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:

1. The errors of electronic universal testing machine:

Error one, electronic universal testing machine:

Errors caused by errors in the test work, negligence and other reasons. This error is irregular and needs to be repeatedly checked to avoid it. Cause: The electronic and electronic universal testing machine is operating incorrectly, the tester reads the number wrongly, and writes the decimal point position in the wrong recording.

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.

2. System error of electronic universal testing machine:

Two, the electronic universal testing machine system error:

Maintain a certain value or error of certain regular changes. System errors are regular, and this rule is reflected in every specific experiment. If you find this rule, you can correct it. The reasons for this problem of electronic universal testing machines are: 1. The electronic universal testing machines are inaccurate indicative, and the measured force value is always too large or too small. 2. When the resistance strain meter measures the coefficient error on the instrument panel.

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 coordinate on the instrument panel.

3. Random error of electronic universal test machine:

Three, the electronic universal testing machine random error:

That is, if the same parameter is repeatedly measured multiple times under the same conditions, the measured values ​​obtained cannot be exactly the same. Causes: 1. Changes in friction force in the test machine during the test process; 2. Changes in environmental humidity, etc.

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.
