Battery for Signal Light Models
1. For models fitted with optional light signal, use leak proof batteries whenever possible. Check the batteries frequently to
avoid corrosion problems, especially if the wrench is used in damp or humid conditions.
2. If the wrench is likely to be stored for a period of time, first remove the batteries before storing.
3. For accessing the battery see drawings below.
Calibration
1. Check wrench against an appropriate torque tester to verify accuracy.
2. After checking, determine if wrench is within tolerance.
Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO 6789:2003
(Tools < 10 N.m (+/- 6% of setting): ADS4 & ADS8 models
(Tools > 10 N.m are +/- 4% of setting): All other Dial Wrench models.
3. If out of tolerance, then make the according adjustments.
Preparation before Calibration
1. Ensure that the wrench spindle rotates smoothly without excessive friction and that the ratchet operates (Not EDS model).
2. Ensure that the rack and pinion assembly operates smoothly and that the main pointer is free to rotate without coming into
contact with the dial or window.
3. Ensure that the torque needed to rotate the slave pointer in the window bush is 0.03 cN.m +/-10% and when rotated the
pointer does not contact the dial face or window moulding.
