WRENCH INSTALLATION
1. Slide the reaction post assembly to the far right of the reaction bar. This will allow the operator
to index a ratchet wrench for insertion into the torque transducer.
2. With the handle of the wrench running along the length of the rig, mount the torque wrench to
be tested in the female square of the transducer.
3. To adjust the reaction assembly slacken the clamp at the rear of the assembly. Move the post
up and down to alter the height, and slide the assembly along the arm to adjust the lateral
position.
4. The ideal wrench orientation is horizontal with the bobbins reacting against the normal hand
position, this is usually the centre of the wrench hand grip.
NOTE:
See drawing on page 5 for details.
Wrench handle should be mounted under the wire strap for safe operation in horizontal or
vertical operation.
ITEMS OF NOTE
1. The gear box makes movement in the output drive difficult to detect. Use the 'A' and 'B' arrows
on the hand wheel and gearbox output as an indication.
ie:- 'A' indicates direction to apply force.
'B' indicates direction to release force.
2. Always ensure the 90° clamp is locked before loading the rig.
3. In the case of a ratchet wrench, with push through square drives, it is important to ensure the
square is operating on the correct side of the ratchet.
4. When rotating the machine, ensure the transducer lead is not caught up in the mechanism.
