2.4: Accuracy

(For full Range specifications see Section 2.2.)

MP200 metering system Clock accuracy: ±3.5 ppm max. (±0.3024 second/

day) over the rated temperature

range

For 23

C, three phase or single phase 3 wire connected balanced load:

For unbalanced voltage inputs where at least one crosses the 150 V auto-scale

threshold (for example, 120 V/120 V/208 V system), degrade accuracy by additional

0.4%.

The MP200 metering system’s accuracy meets the IEC 62053-22 and ANSI C12.20

Accuracy Standards for 0.5% Class Energy meters.
