Section 8. Operation After a card is formatted by a PC, the info sector is not automatically updated. Therefore, when the datalogger boots up, it must determine the bytes available on the card prior to loading the Status table. Traversing the entire FAT of a 16 GB card can take up to 30 minutes or more. However, subsequent compile times are much shorter because the info sector is used to update the bytes free information. Caution - The following feature or information pertains to the CR6 datalogger in concept only. It is not yet adapted to CR6 specifics. Table 88.

Timeseries data have an option to include header, time stamp and record number. See the table TableFile() Instruction Data-File Formats (p. 379). For a format to be compatible with datalogger support software (p. 89) graphing and reporting tools, header, time stamps, and record numbers are usually required. Fully compatible formats are indicated with an asterisk. A more detailed discussion of data-file formats is available in the Campbell Scientific publication LoggerNet Instruction Manual, which is available at www.campbellsci.com. Table 89.
