PQ3350 V5.2 11/10 35
For example, ±0.8W becomes ± 0.8W * CT ratio
Range of CT (Current Transformer) Ratio: 1 to 600
AC Apparent Power (VA, from 0.000VA to 9999 KVA):
VA = V r.m.s. x A r.m.s
AC Reactive Power (VAR, from 0.000 VAR to 9999 KVAR):
VAR =

AC Active Energy (mWH, WH, or KWH, from 0 mWH to 999,999 KWH)
WH = W * Time (in hours)

For CT

≠
1, the accuracy in percentage is the same (±0.5%). But the
additional digits should be multiplied by the CT ratio.
For example, ±0.5A becomes ±0.5A * CT ratio
