Minimum/maximum tracking diagnostic

Minimum and maximum temperature tracking (min/max tracking) when enabled records
minimum and maximum temperatures with date and time stamps on Rosemount 3144P
Temperature Transmitters. This feature records values for Sensor 1, Sensor 2, differential
and terminal (body) 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, 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.

Sometimes it can be difficult to troubleshoot quality issues, or prove
compliance. If your plant historian doesn't capture historical data from
every temperature point, extreme process or ambient temperature
fluctuations cannot be tracked.
By utilizing min/max tracking, you can be confident that you will have
an easily accessible record of all important temperature extremes.
Proving compliance and troubleshooting quality issues become that
much easier.
"Use Min/Max Tracking to verify installation temperature or to
troubleshoot quality issues."
