How to calibrate the range back when the data is inaccurate during the force test of the tension meter?

The operation steps are as follows:

Step 1: Press "↑, ↓" keys to select the number of calibration points;

Step 2:

Press the "OK" key to confirm the use of the selected number of calibration points, and enter the calibration procedure, press the "return" key to enter the 2-point linear calibration by default;

Step 3:

After removing all irrelevant loading weight;

Step 4:

Press the "OK" key to calibrate a "0" point. During the calibration process, the displayed value will flash. After the calibration is completed, the displayed value will stop flashing and display the weight that should be loaded at the two calibration points;

Step 5: Load the relative weights displayed at the two calibration points at this time (if the corresponding weights are not displayed on site, you can press the "↑, ←, →, ↓" keys to set the calibration weights at this point. After setting the weight, press the "OK" button to confirm. Although the value can be set by yourself, it should be as close to the default value as possible, otherwise the measurement result will be biased);

Step 6:

Press the "OK" key to calibrate the weight points displayed by the two calibration points (if the error message "no" is displayed, it means that the actually loaded weight may be wrong and the calibration cannot be performed. Please check the loaded weight and then press " OK” button), during the calibration process, the displayed value will flash. After the calibration is completed, the displayed value will stop flashing and display the weight that should be loaded at the next calibration point (if the selected calibration method is 2-point linear calibration, When the calibration is over, the calibration program will automatically exit).

Step 7:

At this time, the three calibration points display relative weights (if there is no corresponding weight displayed on the spot, you can press the "↑, ←, →, ↓" keys to set the weight of the calibration weight at this point by yourself. Press the "OK" key again to confirm, although the value can be set by yourself, it should still be as close to the default value as possible, otherwise the measurement result will be biased);

Step 8:

Press the "OK" key to calibrate the weight points displayed by the three calibration points (if an error message of "no" is displayed, it means that the actually loaded weight may be wrong and the calibration cannot be performed. Please check the loaded weight and then press " OK” key), during the calibration process, the displayed value will flash. After the calibration is completed, the displayed value will stop flashing. When the calibration is over, the calibration program will automatically exit.

Note: The specific range and division value of the tension meter load link are set according to the specification parameter table in the manual.
