●

Cumulative energy till last month

Cumulative energy till last month states energy consumed till the last calendar month reset.

●

Monthly maximum demand

●

Current monthly cumulative energy

Current monthly cumulative energy states energy consumed in that particular current month

till the last calendar month reset.

●

Monthly average PF

PF average value is the sum of PF readings and PF averaging count is the number of PF

readings.
