Trend Recorder:
The trend recorder allows up to 65 of the 200+ available measurements to be
recorded at intervals of once per second or slower. The maximum is 10
measurements at intervals of once every other cycle or once per cycle (30x/sec or
60x/sec, respectively, at 60 Hz, and 25x/sec or 50x/sec at 50 Hz). Changing the
configuration, including recording interval, measurement type, or selected
measurements, will cause all existing trend records to be erased from the log at
reboot. Enabling or disabling the recorder will not cause the log to be erased.
The trend log is circular. That is, when the entire trend log memory is full, it wraps
around and overwrites the oldest entries in the log. The amount of time that it takes
until the log wraps around depends on how much data are written to each log entry
and the frequency with which the entries are written. The calculated wrap time is
displayed on the trend recorder configuration page and is updated as changes are
made to the configuration.
