10.2 Calibration Procedure
1. Select Calibration from the menu. The display will appear as follows:
The sensor can be calibrated at up to 10 points in each direction. Enter the number of calibration
points for each direction. At least one point must be selected for each direction.
Note: To achieve the accuracy specification of ±0.5% of full scale, it is recommended to calibrate
the sensor at 5 or more even increments in both the clockwise and counter-clockwise directions.
For example, a sensor with capacity of 50 lbFin should be calibrated at 10, 20, 30, 40, and 50
lbFin loads in each direction.
2. To escape the Calibration menu at any time, press ESCAPE. The display will appear as follows:
Selecting “CANCEL” will revert back to the Calibration setup. Selecting “EXIT W/O SAVING” will
return to the menu without saving changes.
3. After the number of calibration points has been entered, press ENTER. The display will appear as
follows:
4. Place the torque sensor vertically in a fixture free from vibration, then press ZERO. The gauge
will calculate offsets, and the display will appear as follows:
