Thermocouple / Temperature Transmitter Loop Checks Procedure
-
Check and verify the DCS configuration for applicable points.
-
Simulate millivolt equivalent to the 0%, 25%, 50%, 75% and 100% of the transmitter / DCS range, by using âmvâ source (simulator) at the thermocouple terminal head.
-
Verify the corresponding reading in the DCS / integral indicator of transmitter and remote indicator if applicable.
-
Alarm functions (in DCS) to be checked by simulating / varying the required signals.
-
Normalize all the connections prior to closing the terminal and confirm ambient temperature at integral indicator of temperature transmitter and at remote indicator if applicable to DCS.
