(5) For the phase-to-earth voltage measurement (phase-neutral). For the phase-to-phase voltage measurement
(phase-phase), in balanced three-phase mode, it is possible to reach 660V
having a phase-neutral voltage of 380V
(6) An additional influence of 3.5°C must be added in an environment disturbed by radiation fields. In other words,
the error in the field of reference in an environment disturbed by radiation fields is ± (1 %+4.5°C).
An additional influence of 6.2°F must be added in an environment disturbed by radiation fields. In other words,
the error in the field of reference in an environment disturbed by radiation fields is ± (1 %+8°F).
NOTE: The uncertainties given for power and energy measurements are maximum for Cos φ = 1 or Sin φ = 1 and
are typical for the other phase shifts.
