(1) In 1000V , Cat. III, providing that voltage between each of the terminals and ground does not exceed 1000V
RMS
(2) Two phase (opposite phases) – same note as (1).
(3) Caution: The absolute value of offset must not exceed 95% of peak amplitude.
In other words, s(t) = S × sin(ωt) + O, we have |O| ≤ 0.95 × S (with positive S).
MAX and MIN values in wave shape mode and the values V
current modes are half-period values.
NOTE: The uncertainties given for power and energy measurements are maximum for |Cos φ| = 1 or |Sin φ| = 1 and are
typical for other phase displacement values.
