(2) Short TI HI and LO.
If TI display does not indicate between -0.0004 and
+0.0004 V, perform b (1) below.
(3) Disconnect short from TI HI and LO.
(4) Connect calibrator OUTPUT HI and LO to TI HI and LO.
(5) Set calibrator output to settings listed in table 11. If TI does not indicate within
limits specified, perform corresponding adjustment.

(1) Adjust A6R28 (DVM zero adjustment) through access hole on front panel for a
TI indication between -0.0001 and +0.0001 V.
(2) Adjust A7R13 (fig. 1) for a TI indication between +9.4999 and +9.5001 V.
(3) Adjust A7R6 (fig. 1) for a TI indication between -9.4999 and -9.5001 V.
(4) Adjust A6R29 (fig. 1) for a TI indication between +94.999 and +95.001.
(5) Adjust A6R15 (fig. 1) for a TI indication between +949.99 and +950.01.
13. Remote Trigger Level (Option 041, AN/USM-459, and 5328AF096)
a. Performance Check
NOTE
Perform remote trigger level only if TI is used in an automated
configuration.
NOTE
Remote trigger level can only be performed in an automated
mode. The TI must be connected to a controller with a properly
configured GPIB IEEE interface card.
NOTE
If a controller and/or software other than the CALSETS fielded
controller and ICE software are used, execute the TI command
strings as required.
(1) Connect equipment as shown in figure 2.
