A-12
The Model 3144P transmitter can be ordered with custom configuration. The
table below lists the requirements necessary to specify a custom
configuration.

Custom Transmitter Configuration (Option Code C1)

Option Code C1 allows you to specify the following data in addition to the
standard configuration parameters.

Transmitter-Sensor Matching Trim to Specific Rosemount RTD
Calibration Schedule (Option Code C2)
The transmitters are designed to accept Callendar-van Dusen constants from
a calibrated RTD schedule and generate a custom curve to match any
specific sensor curve. Specify a Series 68, 65, or 78 RTD sensor on the order
with a special characterization curve (V or X8Q4 option). These constants will
be programmed into the transmitter with this option.

Five-Point Calibration (Option Code C4)

Option Code C4 specifies that the transmitter be verified at the following
five-point calibrations: 0, 25, 50, 75, and 100% analog and digital output
points. Use with option code Q4 to obtain a Calibration Certificate.

Trim to Special Sensor (Option Code C7)

You may order the transmitter trimmed to a special sensor (Option Code C7).
Order this option when using a non-standard sensor type. Refer to Table A-2
on page A-5 for a list of standard sensor types.
A characterization schedule for any RTD can be entered as Callendar-Van
Dusen constants with a Model 275 HART Communicator. The constants can
be entered on site or at the factory. For information on ordering sensors
matched to the transmitter using Callendar-Van Dusen constants, refer to the
Rosemount Sensors Product Data Sheet publication no. 00813-0100-2654
(Volume 1) or 00813-0101-2654 (Volume 2).
When a non-standard sensor is used as the input to the transmitter, the
resistance versus temperature curve for a non-standard RTD, or the millivolt
versus temperature curve for a non-standard thermocouple, is stored in the
transmitter memory. This process is performed at the factory. The transmitter
must be configured for a "special" sensor calibration to access the special
curve, but you may use any standard input when the transmitter is configured
for a "standard" sensor.
When a dual-sensor configuration is ordered with Option Code C7, only one
sensor input can be configured as the "special" sensor. The other input must
be configured as one of the "standard" sensor types available on the
transmitter.
