INFORMATION
Note on saving measured values and configuration data:
Since the following measured values are stored in a non-volatile memory every 5 minutes, an operating
voltage failure can cause an interruption of the recording of max. 5 minutes:
· Comparator timer
· S0 meter readings
· Min. / max. / average values
(without date and time)
· Energy values
Configuration data are saved immediately.
