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 TM 11-6625-2941-14&P and the manufacturers'
manuals for this TI.
d. Unless otherwise specified, all controls and control settings refer to the TI.
HIGH VOLTAGE is used or exposed during the performance of
DEATH ON CONTACT may result if
personnel fail to observe safety precautions.
REDUCE
OUTPUT(S) to minimum after each step within the
performance check where applicable.
b. Connect autotransformer to a
115 V ac
power source and
adjust output to
115 V.
c. Set power switch to ON and allow at least 1 hour for warm-up. If TI has been
disconnected from line power for more than 24 hours, allow at least 24 hours for warm-up
d. Position controls as listed in (1) through (12) below:
