Digital Trim operation that allows adjustment of the output electronics to conform to the plant standard. Three types of analog output trim are available: 4–20 mA Trim, 4–20 mA Other Scale, and Low Power. See “Analog Output Trim” in Section 2 . Low Power is not approved for use with the Rosemount 3051N.

Off-line operation that uses the HART Communicator (Rosemount 275 or Rosemount 375) to copy configuration data from one transmitter to one or more other transmitters that require the same data.

Functions performed with a HART-based communicator and the transmitter which test the transmitter, test the loop, and verify transmitter configuration data. See “Commissioning the Rosemount 3051N with a HART-Based Communicator” in Section 2 .

Process of setting parameters that determine how the transmitter operates.

Output function that increases the response time of the transmitter to smooth the output when there are rapid input variations. See “Damping” in Section 2 .

Sixteen-character field for additional identification of the transmitter, its use, or location. The descriptor is stored in the transmitter and can be changed using the HART-based communicator.

Format function that allows you to adjust the transmitter characterization for purposes of digital calibration to plant standards. Digital Trim includes two separate operations: Sensor Trim and Analog Output Trim. See “Transmitter Functions” in Section 2.

Transmitter function that drives the analog output to a jumper-selectable high or low value in the event of an electronics failure. See “Failure Mode Alarm” in Section 2 .

Factory process during which each sensor module is subjected to pressures and temperatures covering the full operating range. The sensor module memory stores data generated from this process for use by the microprocessor in correcting the transmitter output during operation.

Sensor Trim function in which two accurate, end-point pressures are applied, and all output is linearized between them. The selected end points should always be equal to or outside the LRV and URV. See “Full Trim” in Section 2 .

Communications standard that provides simultaneous analog and digital signal transmission between control rooms and field devices such as transmitters. All Rosemount SMART FAMILY products communicate using the HART protocol.

Lowest value of the measured variable that the transmitter can be configured to measure.
