Min/Max Tracking diagnostic
Minimum and Maximum Temperature Tracking (Min/Max Tracking) when enabled records minimum and
maximum temperatures with date and time stamps on Rosemount 644 HART Head mount Temperature
Transmitters. This feature records values for Sensor 1, Sensor 2, Differential, Average, First Good and
Terminal temperatures. Min/Max Tracking only records temperature maxima and minima obtained since
the last reset, and is not a logging function.
To track maximum and minimum temperatures, Min/Max Tracking must be enabled using a Field
Communicator, AMS Device Manager, Local Operator Interface, or other communicator. While enabled,
this feature allows for a reset of information at any time, and all variables can be reset simultaneously.
Additionally, each of the individual parameter's minimum and maximum values may be reset
individually. Once a particular field has been reset, the previous values are overwritten.
