p. Exercise torque cell as described in (1) through (5) below:
(1) Attach socket wrench (part of adapter set) to torque cell.
(2) Slowly apply torque to torque cell in clockwise direction until full-scale is reached.
NOTE
The indicator will indicate + (positive) for clockwise torque and
- (negative) for counterclockwise torque.
(3) Slowly release torque until only tare torque of wrench is applied.
(4) Repeat (2) and (3) above two more times.
(5) Remove socket wrench from torque cell.
q. Exercise TI as described in (1) through (5) below:
(1) Attach TI to torque cell.
(2) Slowly apply torque to TI and torque cell in a clockwise direction for full-scale
indication on TI. (Ensure that torque cell is not over torqued).
(3) Slowly release torque until only tare torque of TI is applied.
(4) Repeat (2) and (3) above two more times.
(5) Remove TI from torque cell.
NOTE
When
applied
torque
changes
from
clockwise
to
counterclockwise, repeat technique of steps p and q above for
counterclockwise.
NOTE
The calibration point must be approached in the direction of
increasing torque. For higher capacity wrenches, loader should
be used to apply a constant torque.
NOTE
Some micrometer preset torque wrenches indicate when the set
torque has been reached by momentary release action of the
drive for a few degrees. An audible "snap" signal may also be
present at high torque settings.
NOTE
Throughout this procedure use torque cell with adapters
appropriate to TI range.
