6. Preliminary Instructions
a. Personnel should become familiar with the entire bulletin before beginning
this 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.
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.
7. Input Resistance
a. Performance Check
(1) Connect resistance measuring system to TI input HI and LO terminal, using
leads supplied with resistance measuring system.
(2) Measured resistance will be within 0.005% of nominal value.
b. Adjustments. No adjustments can be made.
