Hello,
Yes, calculation of the Total Demand distorsion (TDD) as defined by the Noth American standard IEEE 519 is available on the QualistarPlus CA 8336 and QualistarClass A 8345. This parameter is shown under the name chosen by the IEC 61000-4-7 international standard, THD-%r. It is a ratio between the harmonic orders and the total RMS value of the signal.
