Configuration
3.4.1 Device tagging
Tag
An 8-character free-form text field that can be used to uniquely identify the device.
Long tag
A 32-character free-form text field that can be used to uniquely identify the device. Long tag is only
supported by host systems that are HART Revision 6 or higher.
Descriptor
A 16-character free-form text field that can be used to further describe the device or application.
Message
A 32-character free-form text field that can be used to save a message or memo about the device or
application.
Date
A formatted field (mm/dd/yyyy) available to enter and store a date (such as the day of installation or last
calibration).
3.4.2 Units of measure
The Differential Pressure, P
HI
Pressure, and P
LO
Pressure measurements can be independently configured
for any of the units shown in Tab le 3- 1.
The P
HI
and P
LO
Module Temperatures can be independently configured for Fahrenheit or Celsius.
Table 3-1. Pressure Units of Measure
3.4.3 Damping
The damping software feature introduces a delay in processing which increases the response time of the
measurement, smoothing variations in output readings caused by rapid input changes. Determine the
appropriate damping setting based on the necessary response time, signal stability, and other
requirements of your application.
Damping can be set independently for the Differential Pressure, P
HI
Pressure, and P
LO
Pressure
measurements. Damping values can be set anywhere from 0 to 60 seconds.
