(6) Set the thermocouple calibrator for an output of 1000 F.
(7) Verify that the TI temperature indicator indication is between 998F and 1002 F. Adjust the indicator
high potentiometer as necessary (R15 for digital, and R21 for analog, high adjustments).
NOTE
Interaction may occur between the TI temperature indicator low and high adjustments.
Repeat steps 4 through 7 until no further adjustment is necessary.
(8) Adjust the calibrator output to obtain the temperature values listed below. Record each temperature
indication and verify that these values are within the tolerance limits listed in the table below.
