6. Preliminary Instructions
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 control and control settings refer to the TI.
7. 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
OUPUT(S) to minimum after each step within the performance
check where applicable.
NOTE
BEFORE CONNECTING TI, the protective earth terminal of
the instrument must be connected to the protective conductor
of the line power cord. The line plug shall only be inserted into
a socket outlet provided with a protective earth contact. The
protective action must not be negated by the use of an
extension cord (power cable) without a protective conductor
(grounding). Grounding one conductor of a two conductor
outlet is not sufficient protection.
