AEMC 8335 Power Pad User Manual page 26

Apparent energy
(1) The stated uncertainties on the active power and energy measurements are max for |cos F| = 1 and
typical for the other phase differences.
(2) The stated uncertainties on the reactive power and energy measurements are max for |sin F| = 1
and typical for the other phase shifts.
(3) With MN193 clamp (5A) or 5A adapter.
(4) With AmpFlex or MiniFlex
®
(5) The resolution depends on the current sensor used and on the value to be displayed.
(6) The energy is equivalent to more than 146 years of the associated maximum power (unity ratios).
