GE Multilin EPM 2200 - Accuracy

CHAPTER 2: OVERVIEW AND SPECIFICATIONS ACCURACY
EPM 2200 POWER METER – INSTRUCTION MANUAL 2–9
2.4 Accuracy
For 23 °C, 3 Phase balanced Wye or Delta load.
1
For 2.5 element programmed units, degrade accuracy by an additional 0.5% of reading.
2
For unbalanced voltage inputs where at least one crosses the 150V auto-scale threshold
(for example, 120V/120V/208V system), degrade accuracy by additional 0.4%.
EPM 2200 accuracy meets the IEC62053-22 Accuracy Standards for 0.5% Class Meters.
This standard is shown in the table below.
