From the installation manual:
Series 1000 and 2000 meters provide active energy measurements, which are
displayed on the LCD in 1 kWh resolution. These values are cumulative and
cannot be reset. When configured with the energy demand option, the meters provide
instantaneous readings on the integrated LCD. These values are displayed one at a
time, for six seconds each, as follows:
• Total Active Energy, in kWh (1 kWh resolution, cumulative, non-resettable)
• Instantaneous Demand, in Kilowatts (last 5 minute average, 1/100 kW resolution)
• Peak Demand: Kilowatts (15 minute rolling demand interval, 1/100 kW resolution)
A dot in the LCD aligns with an arrow on the display label to differentiate between
instantaneous and peak demand. After displaying peak demand and before displaying
total energy, the meter tests the LCD by activating all segments simultaneously for
one second.
