	cc		Transducer Coefficients Description		Datum
					Type
00			Re-zero Cal Adjustment (offset) term	(Note 1)	FLOAT
01			Span Cal Adjustment (gain) term	(Note 2)	FLOAT
07			User Defined Field	(Note 4)	INTEGER
09		Transducer Manufacturing Reference Number (Note 5)			INTEGER
	0A		Transducer Full-Scale Range Code (See Appendix F) (Note 5)		INTEGER

(Note 1) Related command ‘w08’ can be used to download the offset term to the sensor’s non-volatile memory (digitally or non-digitally compensated sensor).

(Note 2) Related command ‘w09’ can be used to download the gain term to the sensor’s non-volatile memory (digitally or non-digitally compensated sensor).

(Note 4) Data is immediately stored to the sensor’s non-volatile memory.

The User Defined Date field (cc=07) is a 32-bit integer. Possible uses are to I ndicate the date of last user zero and/or span calibration or possibly the date of next required calibration. If this optional field is used, the user is responsible for correctly encoding the date into the appropriate 32-bit integer value e.g., a decimally encoded ‘yymmdd’ date. Any modifications of this field (using the Download Internal Coefficients (‘v’) command) will result in the new value automatically being entered to transducer non-volatile memory.

A special single Other Coefficients array is selected with array index aa=11 (hex). All the valid coefficient indexes (for this array only) are listed in the following table:
