How to pay attention to the test error of electronic tension testing machine

During the use of the instrument, the operating error of the tensile tester is not achieved. Errors caused by improper installation, adjustment, arrangement, and use. For example: If the instrument that should be placed vertically according to regulations is placed horizontally, the instrument is poorly grounded, the test leads are too long, the impedance matching is not considered, and the measurement is not performed after preheating, adjustment, and calibration is not performed according to the operating procedures.
