The tensile testing machines on the market all use the two display methods of electronic or computer. Both the electronic and computer tensile testing machines have similar solutions to the problems of non-display or inaccurate force values. Today ’s editor Let's analyze the reason why the mechanical value of the tensile test is not displayed and the power is not accurate.
1. The mechanical value of the tensile test is not displayed
1. The tensile force value does not indicate that there is a tensile machine, and the sensor of the tensile testing machine itself is faulty
2. Whether the sensor of the rally machine is damaged, there are reasons for damage, and the natural aging life of the sensor has arrived. Man-made damage overloaded the sensor or accidentally hit the sensor with the lower fixture during the test.
Solution: It is necessary to replace the tension sensor of the force measuring electronic technology.
3. Failure of the main board and circuit of the tensile machine that the mechanical value of the tensile test is not displayed,
Solution: Check whether the connection line of the sensor of the tension machine is in good contact. You can reinsert the connector of the sensor. If it is not resolved, the motherboard of the tension machine may be damaged. Need to contact the manufacturer.
2. The mechanical value of the tensile test is not accurate
1. The sensor is not calibrated or not calibrated and needs to be calibrated again.
solution:
The weight can be adjusted by the manufacturer or requested by the metrology bureau.
2. Fixture problems may cause unstable inherent friction and affect the experimental results.
solution:
Can be connected to the fixture, adjust the fixture to solve
3. It may be that the load of the sensor of the tensile testing machine is too large to accurately measure the terminal force of the small load.
solution:
It can be solved by replacing a smaller sensor.
