Manual, Chapter 6.
(2) Access cables 20090768-1 and 20090769-1 on the T53/T55/T63/T64 side of the J-box. These
cables contain the connectors where the thermocouple calibrator will be installed.
indicated temperature for the respective channel is approximately the ambient temperature (this test
is optional).
(4) For each temperature channel listed in the following tables, perform steps (1) through (4) below.
(a) Connect the thermocouple (TC) calibrator to the specified connector using J-type TC leads.
(b) Adjust the calibrator controls to obtain each specified temperature setting.
(c) At each temperature set point, record the indicated temperature and verify that the recorded
temperature is within the given tolerance limits.
(d) Calibrate the corresponding AEDATS channel in accordance with AEDATS II (H345-1)
Technical Manual, or AEDATS IV (H355-7) Technical Manual.
NOTE
The Limit Control Panel, Temperature and Speed Limit Control (Steps 35, 36, 37, 39, and
40) may be calibrated in conjunction with the channels marked by "*" in the following
table.
