Analog output trim
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" on page
Cloning
Offline operation that uses the HART
configuration data from one transmitter to one or more other transmitters that require the same data.
Commissioning
Functions performed with a HART-based communicator and the transmitter which test the transmitter,
test the loop, and verify transmitter configuration data. See
HART-based communicator" on page
Configuration
Process of setting parameters that determine how the transmitter operates.
Damping
Output function that increases the response time of the transmitter to smooth the output when there
are rapid input variations. See
Descriptor
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.
Digital trim
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
Failure mode alarm
Transmitter function that drives the analog output to a jumper-selectable high or low value in the event
of an electronics failure. See
Factory characterization
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.
Full trim
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
