All the work objects are designed for certain torque values. However, the dials on the Electric Screwdriver provide relative torque values for reference. Therefore, the precision calibration of the torque value is required to ensure the uniformity of the torque value of each screw on the work objects. Hence, the torque tester to provide uniform and accurate torque value is needed. The Electric Screwdriver needs the torque tester to calibrate the dials of the torque to provide the uniformity of the torque value.
