A1 Basic measurements
The basic measured quantities are calculated each 200ms by determining an average over 10 cycles at 50Hz or 12
cycles at 60Hz. If a measurement is available depends on the selected system.
Depending on the measured quantity also minimum and maximum values are determined and non-volatile stored with
timestamp. These values may be reset by the user via display, see
