1000 – 9999 KW
1,2,3
For CT ≠ 1, the accuracy in percentage is the same (±1%). But the
additional digits should be multiplied by the CT ratio.
For example,
Range of CT (Current Transformer) Ratio: 1 to 600
AC Apparent Power (VA, from 0.000VA to 9999 KVA):
AC Reactive Power (VAR, from 0.000 VAR to 9999 KVAR):
AC Active Energy (mWH, WH, or KWH, from 0 mWH to 999,999 KWH)
