Variable Logging

7.6.1

Overview

Variable Logging can be used in a number of ways. The first function is the logging and time-stamping of
the minimum and maximum pressures and module temperatures. The second function is logging and
time-stamping of over pressure or over temperature conditions, events that could have an effect on the
life of the transmitter.

Pressure Variable Logging

HART 5 with Diagnostics Fast Keys
HART 7 Fast Keys
Minimum, Maximum Pressure
The meters indicate the lowest and highest pressure the transmitter has measured since the last time
the value was cleared. Time Since Event indicates the elapsed time since the min/max pressure was
measured.
Both the Min and Max values can be reset independently. Clicking on Reset All Pressure Events will reset
the Time Since Event clock and sets the pressure to the currently measured value.

Time Outside Sensor Limits gives the operator/maintenance personnel an indication of possible
misapplication of the transmitter. The lower and upper operate the same. They both include a Time
Since 1st Event, Number of Events, and Total time.
