(4) Set TI multimeter FUNCTION switch to DC-. If multimeter does not indicate
0, perform b (2) below.
(5) Set TI multimeter FUNCTION switch to DC+ and RANGE switch to 1V.
(6) Connect calibrator to TI multimeter INPUT using probe in table 3 (set to X1).
(7) Adjust calibrator for an indication of 10 on 0 to 10 scale. If calibrator does not
indicate within limits specified in first row of table 15, perform b (3) below.
(8) Repeat technique of (7) above for settings and indications listed in table 15.
Calibrator will indicate within limits specified in table 15.

1 Set
probe X1-X10 switch to X10 for this check only.
Set FUNCTION switch to DC- (see CAUTION below) and reverse input at calibrator.

3 If out-of-tolerance, adjust calibrator for 10.0000 and adjust A2A1A1R82 (fig. 8) for 10 V indication on multimeter.
CAUTION
Before performing negative dc measurement, ensure that dc
output of calibrator is floating from chassis ground. Failure to
do so may result in serious damage to calibrator and/or
multimeter.
(9) Set TI multimeter FUNCTION switch to OHMS and RANGE switch to X1 Ω.
If meter does not indicate (infinity), perform b (4) below.
(10) Connect resistance standard to TI multimeter INPUT, using probe in table 3
(set to X1).
(11) Adjust resistance standard until TI multimeter indicates 30 on OHMS scale. If
resistance standard does not within limits specified in first row of table 16, perform b (5)
below.
(12) Repeat technique of (11) above for settings and indications listed in table 16.
Resistance standard will indicate within limits specified in table 16.
