OVERVIEW Some of the terms used in this manual relate specifically to the
operation of Rosemount transmitters, hand-held communicators, and
other Rosemount products. The following list provides brief definitions.
See the sections listed for additional information.
50 or 60 Hz Setting Hardware- or factory-selectable option to reject line frequency noise
present on the sensor leads. It should be set to the frequency of your
powerline frequency value.
Burst Burst mode is an extension to the HART protocol that provides the
continuous transmission of standard HART command response by a
field device.
Characterize Format function that allows you to configure the transmitter for a
specific input sensor type, set the number of sensor wires, and store the
sensor and transmitter serial numbers. Characterize and Digital Trim
are the two Format functions.
Cloning Off-line operation that uses a HART communicator to copy
configuration data from one transmitter to one or more other
transmitters that require the same data.
Commissioning Functions performed with a HART communicator and the transmitter
to test the transmitter and loop and verify transmitter configuration
data.
Configuration Parameters that determine how the transmitter operates.
Configuration may be performed on-line or off-line.
Damping Output function that increases the time constant of the transmitter
output to smooth the output when there are rapid input variations.
Descriptor 16-character field for additional identification of the transmitter, its
use, or location. The descriptor is stored in the transmitter and can be
changed using a HART communicator and the transmitter information
function.
Digital Trim Format function that allows you to make corrections to the factory-
stored characterization curve used by the transmitter to produce a
process variable output.
Drift Alert Detects drifting in the sensors by sending a warning or alarm when the
user-acceptable difference between Sensor 1 and Sensor 2 is exceeded.
Failure Mode Transmitter function that drives the output to a hardware-selectable
high or low setting during an input sensor failure or a failure in the
transmitter electronics.
