5.5.8 Counters and timers
The following counters are available:

Sensor Wet Count
The count increments each time the Sensor State changes from dry to wet. This
counter can be reset by entering a new value using
Reset/Preset Wet Count .

Calibration Count
The Rosemount 2140 and Rosemount 2140:SIS are calibrated under reference
conditions at the factory. In special circumstances, it may be re-calibrated in the
field and this increments the count.

Fault Count
The count increments each time there is a fault (see “Sensor status” on page 83 ).
This counter can be reset to zero using Reset Fault Count .
The following timers are available when in HART 7 mode:

Time Since Output Change
The time elapsed since the Output State last changed.

Total Time Dry
A totalized time for how long the Sensor State has been indicating ‘dry’.
This timer can be reset to zero.

Total Time Wet
A totalized time for how long the Sensor State has been indicating ‘wet’.
This timer can be reset to zero.
Note
Units for the times are days, hours, minutes, and seconds.
Seconds are not shown for long times.
