I have started design three phase Energy meter using ADE7758(interface SPI); where i am encountering a problem as below.
- When i read three phases voltage alone, then i will get the correct voltages readings as below
if i read the currents along with voltages, then will get the voltage(in decimal) and current(in hex) as below
The R phase will increase to 41 volts and becomes 0.0; mean while current MSB will increase.
From above R current MSB is 05 (0502629) ;
Rvolt = (5 * 41) + 19.684
= 205 + 19.684
Kindly help to resolve the above issue...
