Minor Calibration Accuracy Adjustment
NOTE
A minor (knob/scale) adjustment is used to adjust 20% of the scale reading. If the reading
at 20% and 100% of scale are both either high or low to the required accuracy, a minor
adjustment may be used to bring the accuracy within torque specification. If the torque
wrench requires minor adjustment follow steps 4 through 8.
4. Set the knob so that the scale is at 20% of full scale. Remove the plug from the end of
the knob.
5. Test the screwdriver and Adjust the handle, clockwise to increase and
counterclockwise to decrease the reading, until the screwdriver read within
specification of the 20% reading (example: For a 100 IN.OZ. CDI screwdriver, the low
reading is 20 IN.OZ. and 18.8 to 21.2 IN.OZ. is the tolerance).
