7. Equipment Setup
HIGH VOLTAGE is used or exposed during the performance of
this calibration. 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.
NOTE
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 11-6625-400-12, TM 11-6625-400-35, and
TM 11-6625-2629-14&P for this TI.
NOTE
When indications specified in paragraphs 8 through 12 are not
within tolerance, perform the power supply check prior to
making adjustments. After adjustments are made, repeat
paragraphs 8 through 12. Do not perform power supply check
if all other parameters are within tolerance.
NOTE
Unless otherwise specified, all controls and control settings
refer to the TI.
a. Remove TI protective cover.
b. Connect TI to a 115 V ac source.
c. Energize equipment and allow 30 minutes for warm-up and stabilization.
