The DHLC3 buffers datastrings whilst this LED is alight so no data is lost. Data in the buffer will
be sent to the SDHC card 5 seconds after the LED goes out.
At the configured logging interval the DataHog sends a 'datastring'. This datastring contains
the date and time of the stored data, channel number and data:
This 'datastring' is stored on the SDHCHC card in a 'day file'. A new day file is automatically
created at midnight. Day files are a space delimited text file and easily read by any
spreadsheet software. Please refer to Appendix 7 for details of the SDHC card structure.
