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. When indications specified in paragraphs 8 through 19 are not within tolerance,
refer to the manufacturer's manual and perform a complete alignment.
e. Unless otherwise specified, all controls and control settings refer to the TI.
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.
a. Ensure TI rear panel OVEN REF OUT is connected to EXT REF IN.
b. Connect TI to a 115 V ac power source.
