CHAPTER 4
EPM3000P O
VERVIEW
The EPM3000P and EPM3000P-F measure 10 electrical parameters. Values for each parameter are accessed
through the keypad on the meter's front panel (See Figure 4.1). The meters illustrated throughout the manual are
EPM3000P except for Figure 4.1 below. The EPM3000P-F (Frequency Option) displays the Frequency measurement
on the face of the meter. Max, Min and Limits indicators are on the left side of the face.

The max/min values represent the highest and lowest average demand over a user programmable time period, know
as the INTEGRATION INTERVAL. The readings are calculated using a rolling average technique. Each second, a
new reading is used to calculate the max/min and the last reading of the interval is dropped.
