Appendix D. Output Tables
RawData
The RawData table stores each sample of the AP200 data (two records per
second). This table is normally used only for troubleshooting. The files on the
card and in the CPU are allocated to use remaining available space. The
number of days for which space is available on the card will depend on the
options chosen. The first set of values is always stored in RawData. The air
temperature profile data are stored as determined by constant N_AirTemps.
The remaining values are stored only if the constant SaveAll_diagnostics =
True. This constant may be set to False to reduce the amount of data stored or
set to True to allow more detailed analysis of diagnostic values for
troubleshooting. See Section 5.4.2, Compile Switches, for details on setting
program constants. A 2GB card will store over 50 days with all diagnostics, or
over 100 days if SaveAll_diagnostics = False. The actual table fill time for
the RawData table can be seen in the datalogger status table by either using
LoggerNet or with a keyboard display.
