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 tables 2 and 3.
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. When indications specified in paragraphs 8 through 14 are not within tolerance,
perform the power supply check prior to making adjustments. After adjustments are made,
repeat paragraphs 8 through 14. Do not perform power supply check if all other
parameters are within tolerance.
e. Unless otherwise specified all controls and controls 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
For option 020, a 4 step operation (parameter, channel/data
and entry) is required when changing parameters except when
changing pulse period or burst which is a 3 step operation
(parameter, data, and entry). For standard model only, a
3 step operation (parameter, data, and entry) is required for all
parameters.
NOTE
Remove protective cover when necessary to make adjustments
and to locate test points.
a. Set VOLTAGE SELECTOR switch (rear panel) to 115 V position.
b. Connect TI to 115 V ac power source.
c. Press RCL ON/OFF pushbutton to ON position.
