The tension test machine corrects the speed and force value

one,Tension testerSpeed ​​correction:

1. First record the initial position of the machine crossbar and select the speed value on the control panel (using a standard straight steel ruler to measure the crossbar stroke).

2. At the same time as the starter is started, the electronic stopwatch starts to count for one minute. Press the machine stop button while the stopwatch arrives. According to the time of the stopwatch, record the cross-load stroke value and the speed of each minute (mm/min), observe the difference between the cross-load stroke value and the straight steel ruler, and calculate the cross-load stroke error value, which should not exceed ±1%.

two,Tension testerPower value correction: After entering the computer program, open the calibration interface, press the test start, take a standard weight weight and lightly hang it on the upper fixture connection seat, record the computer display force value, and calculate the difference with the standard weight weight. The error should not exceed ±1%.
