Lowest value of the measured variable that the analog output of the transmitter is currently configured to measure.

The connection of several transmitters to a single communications transmission line. Communication between the host and the transmitters takes place digitally with the analog output of the transmitters deactivated. Note that although the Rosemount 3051N has multi-drop capability, which is a HART protocol feature, the Rosemount 3051N is not qualified/dedicated for use in multi-drop mode.

Configuration function that changes the transmitter 4 and 20 mA settings. See “Rerange” in Section 2 .

HART-based communicator command that transfers configuration data from the hand-held communicator’s memory to the transmitter memory.

Digital Trim function that allows you to adjust the digital process variable reading to a precise pressure input. Zero Trim and Full Trim are the two Sensor Trim functions. See “Sensor Trim” in Section 2 .

Term used to describe instruments that are microprocessor-based and feature advanced communications capabilities. See Section 1: Introduction.

Rosemount pressure, temperature, level, and flow instruments with microprocessor-based digital electronics.

Algebraic difference between the upper and lower range values.

Eight-character field for identifying the transmitter. The tag is stored in the transmitter and can be changed using the HART Communicator (Rosemount 275 or Rosemount 375) and the Transmitter Information function.

Unique number (1-15) used to identify a multidropped transmitter. Transmitters that are not multidropped have 0 as an address. Note that although the Rosemount 3051N has multi-drop capability, which is a HART Protocol feature, the Rosemount 3051N is not qualified/dedicated for use in multi-drop mode.

Jumper-selectable feature that prevents accidental or deliberate changes to configuration data. See “Transmitter Security” in Section 2 .

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

Highest value of the measured variable that the analog output of the transmitter is currently configured to measure.

A zero-based, one-point adjustment used in differential pressure applications to compensate for mounting position effects or zero shifts caused by static pressure. See “Zero Trim” in Section 2 .
