Diagnostic State
The Diagnostic State contains a toggle to enable (ON)
or disable (OFF) built-in dirty sensor diagnostic
detection. Dirty sensor detection monitors the drive
level necessary to make the conductivity
measurement. As resistive coats build on the sensor,
the drive level will increase. At an internal set level,
the transmitter will issue a detected fault condition to
indicate the sensor requires cleaning.
