Information displayed under TX INFO common
for all HART transmitters
TX : Model type of transmitter.
BY : Manufacturer of transmitter.
TAG : Tag name identifier of unit.
DESCRIPTOR : The transmitter service.
MSG : A message that can be written, using the P.C.
Configurator, for warning or maintenance use.
DATE : User specifiable date. May be used to log the
installation, calibration or last servicing date.
DEV NUM : Factory assigned electronics serial number.
UNITS : Engineering units for reporting process value
or entering range values.
LRV : Lower Range Value. The lowest value that the
transmitter is adjusted to measure. Also known as the
zero or 4 mA point.
URV : Upper Range Value. The highest value that the
transmitter is adjusted to measure. Also known as the
full span or 20 mA point.
DAMPING : The time constant, in seconds, of a first
order filter applied to the input.
OUTPUT : Type of the transfer function applied to the
input to obtain the output. Linear, Square root and
Polynomial for 600T Tx (not for temperature transmitter).
LIMS UNITS : Units used to express the sensor's
calibration limits.
MIN SPAN : The minimum allowed value for the span.
The span is the algebraic difference between the Upper
and Lower Range Values.

USE OF THE GREEN KEYS - REVIEW

The dedicated function key REVIEW allows the user to view the transmitters
configuration data. The information contained under Tx Info varies slightly
depending on transmitter type. See below the relevant information for
600T and 600T EN Pressure and for 652/653S Temperature transmitters.
Each parameter of a section is normally displayed at a rate of approxima-
tely 2 seconds. The listing of the parameter may be stopped (F1 - STOP
LIST), started again (F2 - STRT LIST), advanced (F3 - NEXT ITEM) or
LAST
backed-up (F4 - LAST ITEM).
ITEM
The information for Deltapi K and KST Tx are described next in this
section.
LRL : Lower Sensor Limit. The lowest value of the
measured value that the transmitter can be adjusted to
measure.
URL : Upper Sensor Limit. The highest value of the
measured value that the transmitter can be adjusted to
measure.
FINAL ASSY NUMBER: the transmitter final assembly
serial number.
P V SENSOR S/N : The sensor's module serial number
(not for temperature transmitter)
H / W : Electronics hardware revision level
S / W : Electronics software revision level
U C D : HART Universal Command document revision
level which the HART protocol was implemented
T S D : Transmitters Specific document revision level
For both 600T and 600T EN pressure transmitter
MAX WORKING PRES. with its units :
The maximum pressure to which the transmitter can be
submitted without causing danger and damage.
MAX SENSOR TEMP. with its units :
The maximum temperature to which the transmitter's
sensor can be submitted without damage.
MIN SENSOR TEMP. with its units :
The minimum temperature to which the transmitter's
sensor can be submitted without damage .
ROOT XFER FUNCTION: (not for 600T EN)
The output variation from 0% to 20% of the output, when
the SQR(x) output transfer function is selected.
