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 and item identification number as listed in tables 2 and 3. For the identification of
equipment referenced by item numbers prefixed with A, see table 2, and for prefix B, see
table 3.
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 11-6625-2975-40 for this TI.
d. When indications specified in paragraphs 8 through 17 are not within tolerance,

a. Remove protective cover from TI.
b. Connect TI to a 115 V ac source.
c. Energize equipment and allow at least 30 minutes for equipment to warm-up
and stabilize.
NOTE
A computer memory check is performed immediately after
power is turned on. If an incorrect output occurs, the number
of the malfunctioning memory is displayed on the
