Logging screen
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.
Total Time Above / Below
This is the accumulated time the pressure sensor has been in an
over-pressure condition. This elapsed total time is independent of the number
of events or frequency; it is the total or sum time the transmitter was in this
condition. These values are not resettable.
Time Since 1st Event
The elapsed time since the first over-pressure was detected. This time can be
reset by clicking the Reset Time Since 1st Events button.
Number of Events
This is the number of times the pressure sensor has been in an over-pressure
condition. These values are not resettable.
Reset Time Since 1st Events
Selecting this reset will set the Since 1st Event for both Above Upper Sensor
Limit and Below Lower Sensor Limit to zero.
Reset All Pressure Events
Selecting this will reset all values on this screen to zero with the exception of
Total Operating Time, the Total Time above and below sensor limit, and the
Number of Events for above and below sensor limit.
