Specifications and Reference Data
External ground screw assembly
The external ground screw assembly can be ordered by specifying code G1 when an enclosure is
specified. However, some approvals include the ground screw assembly in the transmitter
shipment, hence it is not necessary to order code G1. The table below identifies which approval
options include the external ground screw assembly and which do not.
Custom configuration
Custom configurations are to be specified when ordering. This configuration must be the same
for all sensors. The following table lists the necessary requirements to specify a custom
configuration.

C2:Transmitter – Sensor Matching
The transmitters are designed to accept Callendar-Van Dusen constants from
a calibrated RTD. Using these constants, the transmitter generates a custom
curve to match the sensor-specific curve. Specify a Series 65, 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.
A1, CN, or C8: Alarm Level
Configuration
A1: NAMUR Alarm and Saturation Levels, with High Alarm configured
CN: NAMUR Alarm and Saturation Levels, with Low Alarm configured
C8: Low Alarm (Standard Rosemount Alarm and Saturation Values)
Q4: Three-Point Calibration with
Certificate
Calibration certificate. Three-Point calibration at 0, 50 and 100% with
certificate.
C4: Five-Point Calibration
Will include five-point calibration at 0, 25, 50, 75, and 100% analog and
digital output points. Use with Calibration Certificate Q4
HR7: HART Revision configuration
Your 644 Head mount and Field Mount devices are HART revision selectable.
Order the HR7 code to configure your device to operate in HART Revision 7
mode. Your device is also configurable in the field. Refer to the 644 Quick
Start Guide or Reference Manual for more instructions.
