CALIBRATION PROCESS FOR PROGRAMMABLE
PULSE HEAD TEKTRONIX, TYPE 015-0611-00
23. Preliminary Instructions
a. The instructions outlined in paragraphs 23 and 24 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.
d. Unless otherwise specified, all controls and control settings refer to the TI.
24. Equipment Setup
WARNING
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. Remove TI bottom protective cover, as required, for adjustments.
b. Connect TI to programmable calibration generator OUTPUT.
c. Connect programmable calibration generator to a 115 V ac source.
d. Energize programmable calibration generator and allow at least 30 minutes for
warm-up and stabilization.
