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
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.
HIGH VOLTAGE is used or exposed during the performance of
personnel fail to observe safety precautions.
CAUTION
When operating with low range torque cells (TI), apply full load
slowly and cautiously to prevent damage.
d. Unless otherwise specified all controls and control settings refer to the TI.
