Due to different working conditions, different types and batches of
bolts, varying friction, etc., it is necessary to set the span based on site
conditions.
2. Adjust the span value using key  or  . Values range from -5 to +5. A
span setting of 0 means no span is set. Save the span value by pressing
key

7.5.2 Calibration
When the wrench reaches a set torque, there is a one-to-one
correspondence between the value read by an external sensor and
the sensor within the tool. We strive to bring these values into close
agreement in this procedure.
By recording six sets of calibration values, the linear relationship between
the set torque and the actual torque can be obtained, and the set torque
can be converted into an intermediate torque value through the linear
relationship.
The new shutdown condition is obtained by the intermediate torque value.
The new shutdown condition is given to the controller to produce the
torque within the allowable range of error with the set torque.
