4.7 Setting the PT (Potential Transformer) Ratio, CT
(Current Transformer) Ratio, and SC (Scaling Factor)
When the secondary side of the PT is connected, by setting the PT ratio, it is
possible to directly read the primary side of the PT.
When the secondary side of the CT is connected, by setting the CT ratio, it
is possible to directly read the primary side of the CT.
By setting the SC, power values can be multiplied by a coefficient.
(1) Enter the PT/CT ratio and SC setting state.
1. Press the
SHIFT
key and the SHIFT indicator is lit.
2. Press the
PT
