Step 6:
Using the torque analyzer or sensor, adjust the tool to the target torque calculated based off of percentages of the max torque shown below. The tool must be set to the target value from a lower setting.If the target is exceeded, the tool must be adjusted below the target and readjusted up.

Step 7: Using the torque analyzer or sensor apply ten (10) loadings and record all values. All ten of these values must be within ±6% of the target and the average of the recorded values must be within ±2% of the Target. If either of these criteria is not met, adjust the tool as necessary and repeat.
Press the Lever button to capture the value.
Step 8:
Once the above criteria are met, press the Lever button to set the setting to the tool. Once the above criteria are met, press the Lever button to store the setting to the tool. The number shown is the calibration factor for that tool setting.
Note: The power button may be pressed several times without any issues if the display does not change immediately.
