C-2
Lower Range Value
(LRV)
Lowest value of the measured variable that the analog output of the
transmitter is currently configured to measure.
Multidropping 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.
Reranging Configuration function that changes the transmitter 4 and 20 mA settings.
Send Data Field Communicator command that transfers configuration data from the
hand-held communicator’s memory to the transmitter memory.
Sensor Trim Digital trim function that allows you to adjust the digital process variable
reading to a precise pressure input. Zero trim and sensor trim are the two
sensor trim functions.
Smart Term used to describe instruments that are microprocessor-based and feature
advanced communications capabilities.
Span Algebraic difference between the upper and lower range values.
Tag Eight-character field for identifying the transmitter. The tag is stored
in the transmitter and can be changed using the Field Communicator and the
transmitter information function.
Transmitter Address Unique number (1-15) used to identify a multidropped transmitter.
Transmitters that are not multidropped have 0 as an address.
Transmitter Security Jumper-selectable feature that prevents accidental or deliberate changes to
configuration data.
Upper Range Limit (URL) Highest value of the measured variable that the transmitter can be configured
to measure.
Upper Range Value
(URV)
Highest value of the measured variable that the analog output of the
transmitter is currently configured to measure.
Zero Trim A zero-based, one-point adjustment used in differential pressure applications
to compensate for mounting position effects or zero shifts caused by static
pressure.
