Figure 12 Block diagram DVS74.G2

The whole platform is configured with RC power supply, current sampling by shunt, voltage sampling
by resistor divider, and each phase uses separated measuring IC V9260 or V9240 in case of type G2.
With microprocessor STM32L158VT6 or V8530 for type G2. RTC provides the time clock source.
Data storage by EEPROM. Display by segment LCD according to FNN
