14.8: Performance Notes
Pst and Plt average time are synchronized to the clock (e.g. for a 10 minute average, the times will
occur at 0, 10, 20, etc.). The actual time of the first average can be less than the selected period to
allow for initial clock synchronization.
If the wrong frequency is chosen (e.g. 50Hz selection for a system operating at 60Hz), Flicker will
still operate but the values computed will not be valid. Select carefully.
User settings are stored. If Flicker is on and power is removed from the meter, Flicker will still be
on when power returns. This can cause data gaps in the logged data.
The Max and Min values are stored and are not lost if the unit is powered down.
Flicker meets the requirements of IEC 61000-4-15 and former IEC 868. Refer to those
specifications for more details, if needed.
Operation is at 230V for 50Hz and 120V for 60Hz as per specification. If the input voltage is
different, the system will normalize it to 230V or 120V for computational purposes.
