DATA BACKUP / POWER FAILURE

To prevent data loss in case of power failure, all relevant data are stored
in non-volatile EEPROM. This takes place if voltage is falling below a
defined level. Also automatically every 24 hours to save all relevant
data in non-volatile EEPROM.

CALIBRATION PULSE / CALIBRATION CONSTANT

The red LED on the front is proportional to the active power.
The pulse constant is 10 Imp./Wh
The pulse duration is 2msec.
Pulses are sent for energy direction import and export

D0 INTERFACE ACCORDING TO EN 62056-21

The D0 (optical) interface is located on the front, right next to the
display.
The multicount D5-xxx-MID have a serial D0 interface according
to EN 62056-21. The D0 interface can be configured as bidirectional
(Mode A or C) or as a unidirectional (D0 mode) communication
interface.
