Note 1 - Display of O.L above 1500kW in single-phase (1000V x 1500A).
Note 2 - Any applied voltage greater than 1000V causes the emission of an
intermittent alarm beep to report a dangerous overload.
Note 3 - The measurement result may be perturbed by an instability linked to the
current measurement (approximately 0.1A).
Example: for a power measurement made at 10A, the instability of the
measurement will be 0.1A/10A or 1%.
