3. Disregarding any scale or bezel markings, rotate the adjusting sleeve as required until the
test device displays a reading equal to the first setting on the wrench and at the same time
ensure the lock mechanism has engaged with one of the ten lock positions in the handle
tube. It should be possible to feel and hear this action, which will be confirmed by pushing in
the red knob to lock the tool. Ensure that the tool is operated as slowly as possible during
the test procedure.
4. If, to achieve the correct reading the zero position on the bezel is no longer in alignment with
the centre line of the main scale, unscrew the three socket set screws by two full turns each
and rotate the adjusting sleeve until the zero position is in alignment with the centre line of
the main scale. (A 1.5 mm A/F hex key is required for the screws).
5. Apply a minimal amount of Loctite 222 to the threads of each screw and carefully “nip up”
each of the screws evenly with sufficient torque to enable the tool to be adjusted.
6. Re-test the tool and if satisfactory readings are obtained throughout the range, fully tighten
the socket screws and release the rubber grip to its original position.
7. If, after several attempts, should it be found impossible to obtain satisfactory readings, it is
recommended that the tool be returned to the manufacturers for re-calibration.
