Notes:
1) Errors determined during energy measurement using a demoboard and a reference meter with high
accuracy (0.05%), which calculates the actual error.
2) Difference between largest and smallest error of 20 successive error samples; maximum meter constant:
1,600i/kWh; reference meter: 10,000 x DUT-meter-constant; measured at 5% Ib, Ib and Imax.
3) What is used for system considerations/calculations.
