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 procedure 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.
Software 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 software adjustments are being performed, the normal process is to enter the
input value followed by the delimiter, (comma) and security code 3457 using MATH keys
then press ENT key. However, if the security code has been disabled, the process will be to
