The User Defined Date field (cc=07) is also a 32-bit integer which may be
encoded in a similar manner. 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. 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.
The Date of Factory Calibration field (cc=08) identifies the date of factory
calibration for the DH200 transducer (9116). It is stored internally as a 32-bit
integer whose value (viewed as a decimal number) is in the format of yymmdd
(year, month, day).
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:
