a. Performance Check
(1) Set function switch to ohms and range switch to first ohms range listed in
calibration performance limits and adjustments table for TI being calibrated.
(2) Short test leads together and adjust ohms adjust for a 0 indication on TI ohms
scale.
NOTE
Perform (2) above for each range prior to making resistance
check on the range.
NOTE
Connect resistance standards NO. 1, NO. 2, and NO. 3 in
series, as needed, to obtain required resistance values.
(3) Connect TI to resistance standard NO. 1.
(4) Adjust resistance standard for required indication on TI as listed in table. If
resistance standard does not indicate within limits specified, and an adjustment is listed,
adjust resistance standard for nominal value and perform adjustment for required
indication on TI.
(5) Repeat technique of (1), (2), and (4) above for the remaining ohms ranges.
b. Adjustments. No further adjustments can be made.
NOTE
The sets of tables below for each instrument are setup as
follows; a = specifications, b = Dc volts, c = Ac volts, d =
resistance and e = Dc current. If a table is not present, that
parameter is not checked on that instrument.
a. Performance Check
(1) Set function switch to dc amps and range switch to the first dc current range
listed in the calibration performance specifications and adjustments table for the TI being
calibrated.
(2) Set calibrator to initial output 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 dc current ranges.
b. Adjustments. No further adjustments can be made.
