4.5.3.2 Daily archive data
Recording of daily data changes with start of day (Refer to 3.2.1.1.3.4) setting.
The smallest and largest instantaneous values measured during one day period, are
saved as minimum and maximum values. Likewise, average values of measurements,
which were taken in one day period, are saved as average values.
14h function operates with file numbers. File numbers 5001 – 5240 are used for
DAILY data.
Klea has a memory that is reserved for daily files. It can keep totally 240 daily files.
When Klea’s daily memory is filled completely, oldest record is deleted and new
record is saved in the deleted record’s memory.
