(2) Access cables 20090787-1 and 20090767-1 on the T700 side of the J-box. These cables contain the
thermocouple connectors where the TC 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 (a) through (d) below.
(a) Connect the thermocouple (TC) calibrator to the specified connector using J-type TC leads.
(b) Adjust the TC calibrator controls to obtain each specified temperature setting.
(c) Record the indicated temperature at each setting 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 (paragraph
