Cold Point Compensation
Cold points are automatically compensated if thermocouples are used. Temperature readings are taken
immediately at the plug near the connection
Calibration
This module need not be calibrated by the end user because it is calibrated after fabrication.
It can only be calibrated once because the calibration values are kept on memory.
The calibration objects (2010:n; 2011:n and 2012:n) in the Startup Parameters are intended for internal use
only.
