2–4 EPM 2200 POWER METER – INSTRUCTION MANUAL
SPECIFICATIONS CHAPTER 2: OVERVIEW AND SPECIFICATIONS
window demand is a fixed window demand that moves for a user-specified subinterval
period. For example, a 15-minute demand using 3 subintervals and providing a new
demand reading every 5 minutes, based on the last 15 minutes.
Utility demand features can be used to calculate kW, kVAR, kVA and PF readings. All other
parameters offer maximum and minimum capability over the user-selectable averaging
period. Voltage provides an instantaneous maximum and minimum reading which
displays the highest surge and lowest sag seen by the meter.
