The accuracy guarantee range is between 20% and 100% of the maximum range, and the torque accuracy is the normal value. The middle groove of the five grooves on the grip is the calibration point. To ensure accuracy, it is recommended to calibrate once a year.
When the work does not reach the lower limit value or exceeds the upper limit value, the light will emit a red light warning; When the work reaches between the lower and upper limit values, the light emits a green light indication. Five torque units: N.m/in-Ib/ft-lb/kg-cm/angle can be freely switched.
Power supply: Two No. 5 batteries.
Power saving mode: can be set to automatically shut down for 2-180 minutes without use.
