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.
