CALIBRATION PROCESS
6. Preliminary Instructions
a. The instructions outlined in paragraphs 6 and 7 are preparatory to the calibration
process. Personnel should become familiar with the entire bulletin before beginning the
calibration.
b. Items of equipment used in this procedure are referenced within the text by common
name as listed in table 2.
c. Unless otherwise specified, verify the result of each test and, whenever the test
requirement is not met, take corrective action before continuing with the calibration.
Adjustments required to calibrate the TI are included in this procedure. Additional
maintenance information is contained in the manufacturer's manual for this TI.
d. Unless otherwise specified, all controls and control settings refer to the TI.
7. Equipment Setup
a. Remove TI from case.
b. Visually check TI for damage.
c. Remove any dirt or grime that may have accumulated around mechanism by using
stiff, clean brush and wiping with clean cloth.
d. Secure holding fixture or torque adapter to a stable, rigid work surface.
e. Allow equipment to stabilize at ambient temperature.
NOTE
This procedure normally covers calibration in cw direction. A
ccw calibration can be accomplished by reversing directions
outlined in each performance check. Torque wrenches will be
calibrated by applying increasing torque only in the clockwise
direction, unless ccw direction is specifically requested by
owner/user.
f. Connect torque tester to a 115 V ac power source. Set power switch to ON and allow
unit to warm-up for 30 minutes.
g. Exercise TI as described in (1) through (5) below:
