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 and/or technical
manuals for the TI.
variety of multimeters.
e. Unless otherwise specified, all controls and control settings refer to the TI.
7. Equipment Setup
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.
8. Dc Voltage
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 displayed output 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.
9. Ac Voltage
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
