NOTE
To gain access to the TI Temperature Indicator alignment controls, remove the two screws
from the sides of the front panel and remove the panel. The two potentiometers are visible
at the upper left of the display. Potentiometer R44 (Front Panel ZERO) controls the ice
point indication and R45 (SPAN) controls the positive (+) full scale indication.
(6) Adjust the thermocouple calibrator controls to a temperature of 1000 F.
(7) Verify that the temperature indicator reads between 999 to 1001 F. Adjust the indicator positive (+)
full-scale adjustments. Repeat the previous four steps until no further adjustment is necessary.
NOTE
Interaction may occur between the TI temperature indicator ice point and positive (+) full-
scale adjustments. Repeat the previous four steps until no further adjustment is
necessary.
(8) Adjust the thermocouple calibrator controls to obtain the temperature values listed below. At each
temperature setting, verify that the TI indicated temperature is within the tolerance limits.
(9) Do not calibrate AEDATS EODT at this time, as it will be calibrated in the next section.
