7.0 KWH/DEMAND METER FEATURES & 

FUNCTIONS*

(*Applies to meters equipped with the Demand Option) 

7.1 KWh/Demand Meter Display Functions 

The Class 2000 kWh/Demand meter has a single display window that cycles through 

the energy data screens. The meter will cycle through four (4) separate screens. The 

screens are described below. 

KWh display shows the amount of energy 

consumed in kilowatt hours (kWh). Reading is 

in whole numbers, there are no decimals and 

the meter requires no multipliers. 

LOAD display shows the present circuit load 

in kilowatts.

KW display shows the electrical Demand in 

kilowatts (kW). Demand interval is either 15 

minutes, 30 minutes or 60 minutes. (Default is 

15 minutes.) 

Time display shows the time of the day that 

the demand peak occurred. 

Date display shows the date of the demand 

(kW) peak.
