ABSTRACT:
A high speed capacitance test set (10 or 60), comprised of a digital test circuit portion (11 or 11') and a multi-pulse train generating portion (12 or 12'), is adapted to make exceedingly rapid, repetitive capacitance measurements, such as required when winding roll-type capacitors to a precisely ascertained final value of capacitance, determined on-the-fly.
