The User Defined Date field (cc=07) is a 32-bit integer. Possible uses are to
indicate 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:

Examples:
! Send TCP/IP command to module (i.e., via its connected socket): with replacement
values for the channel’s offset and gain correction terms loaded into the module’s
volatile memory (cc=00-01). Load these into channel # 8's Transducer Coefficient
array (aa=08).
“v00800-01 0.000 1.000”
Response returned is:
“A”
! Send command to module (via its connected socket) to change its default EU output
from psi to kPa. This will be done by changing the EU Pressure Conversion
Scaler to 6.894757.
“v01101 6.894757”
Response returned is
