CALIBRATION PROCESS
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
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 manufacturers' manuals for this TI.
d. Unless otherwise specified, all controls and control settings refer to the TI.
a. Connect calibrator to TI V
(volts) and COM inputs.
V
2000 mV.
b. Set TI function switch to DC
a. Performance Check
(1) Set calibrator output for 1.9 V. TI will indicate within limits specified in table 3 for
the 2000 mV range.
