CHAPTER 3: ELECTRICAL INSTALLATION

GE Multilin EPM 5000 series Advanced Power Meters 9

• The meter and terminal module DSP3 are factory calibrated together; the serial numbers are matched

on both. The DSP3 input module and the meter base MUST MATCH!

• Mismatching of the meter and DSP3 input module will cause inaccurate readings because calibration

ratios are stored in the meter’s memory, not in the DSP3 input module.
