Correction of positive and negative error of force value of electronic tensile testing machine
1. When the electronic universal testing machine is in the inspection, when the positive and negative errors appear in the test machine, the test value and the corresponding standard force value are generally artificially corrected.
2. When the indication error is negative, and it is linear.
First of all, at the time of verification, the actual error number of each verification point must be recorded, and then the calibration is performed. The standard force value of each calibration point becomes the standard force value minus the actual error number, and then input, then it can be adjusted, such as: When the standard force value is 200KN, the error is -4.2KN. In the calibration, when the display is 195.8KN, the key is confirmed and the value is input.
3. When the indication error is positive error and linearly using the same method above, the standard force value at each calibration point becomes the standard force value plus the actual error number, and then input, you can adjust it to show When the value error (positive error or negative error) is not linear, it needs to be calibrated by the above method, and then calibrated by the conventional method, then it can be adjusted.
