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 (9016) or 9400 transducer (9021/9022. 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).
