e. Unless otherwise specified, all controls and control settings refer to the 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.
a. If necessary, mechanically zero meter pointer, using adjustment screw on meter face.
b. Connect test leads to TI COM (-) and VOA (+) jacks.
a. Performance Check
(1) Set function switch to dc volts and range switch to first dc voltage range listed in
calibration performance specifications and adjustments table for TI being calibrated.
(2) Connect TI to calibrator OUTPUT HI and OUTPUT LO, observing polarity.
(3) Set calibrator to initial output as listed in table.
(4) Rotate calibrator knob, below EDIT FIELD pushbutton, for the required
indication on TI. If calibrator err display does not indicate within limits specified, and an
adjustment is listed, adjust calibrator for nominal value and then perform adjustment for
required indication on TI.
(5) Repeat technique of (1), (3), and (4) above for the remaining dc voltage ranges.
b. Adjustments. No further adjustments can be made.
a. Performance Check
(1) Set function switch to ac volts and range switch to first ac voltage range listed in
calibration performance limits and adjustments table for TI being calibrated.
(2) Set calibrator to initial output and frequency as listed in table.
(3) Rotate calibrator knob, below EDIT FIELD pushbutton, for the required
indication on TI. If calibrator err display does not indicate within limits specified, and an
adjustment is listed, adjust calibrator for nominal value and then perform adjustment for
required indication on TI.
(4) Repeat technique of (1), (2), and (3) above for the remaining ac voltage ranges.
b. Adjustments. No further adjustments can be made.
