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. 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. Insert TI into frequency counter.
b. Connect frequency counter to 115 V ac source.
c. Position frequency counter controls as listed in (1) through (3) below:
(1) SIGNAL INPUT switch to PLUG-IN.
(2) TIME BASE switch to 1s.
(3) FUNCTION switch to FREQUENCY.
d. Energize equipment and allow 30 minutes for equipment to warm-up and stabilize.
