VARIABLE LOGGING
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. Figure 7-21 shows the Pressure Variable
Logging screen. Figure 7-22 shows the Temperature Variable Logging
screen.
Pressure Variable Log 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.
