Lowest value of the measured variable that the
transmitter can be configured to measure.
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.
Configuration function that changes the
transmitter 4 and 20 mA settings.
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 sensor trim are the
two sensor trim functions.
Term used to describe instruments that are
microprocessor-based and feature advanced
communications capabilities.
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 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.
Jumper-selectable feature that prevents
accidental or deliberate changes to configuration
data.
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.
