Sensor Diagnostics
Sensor Drift Alert using Range Alarms and Sensor Corrosion Detection can also be used for
predictive diagnostics to warn of future problems.
Broken Wire Holdoff Time allows you to add an additional time delay before a sensor broken
wire is reported which provides some noise immunity and prevents false alarms caused by other
factors that may be misinterpreted as Broken Wire.
Please refer to Section 1 for more detailed information on Sensor Diagnostics.
Input Quality Alarms
The THZ

/TDZ

also allows the user to determine how certain types of input quality issues are
handled and how they can affect the Device Variables, Dynamic Variables and AO. There are
3 different quality alarms: Measurement out of Conformance Range, Allow Limited and Allow
Dropping. See Section 6 for more information.
