CHAPTER 4 EPM3000P OVERVIEW 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. VOLTS AMPS A-N A B-N B C-N C A-B N B-C C
