4.1.- MEASURING PARAMETERS
The device displays the electrical parameters shown in the following tables.
Where: III = Three-phase, ∑= Total, MAX = Maximum value, MIN = Minimum value, M = Measured value, C=
Calculated value, M/C = Measured value (M) if the Neutral transformer has been connected, if not the value is
calculated (C).
