For power cycle tracking even in presence of transients and noise, PA4000 uses 2 spiral shunts – one for current measurements up to 1 A, and one for current measurements up to 30 A – on each channel and high-speed digital signal processing algorithms. Application-specific test modes are provided as standard, along with LAN, USB, and RS-232 interfaces; harmonics measurement capability up to 100th harmonic; and software for controlling analyzer, downloading measurements, and logging on PC.
