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
).
