Analysis Engine II
A built-in 18-bit A/D converter provides a broad dynamic range.
Even loads with large f luctuations can be shown accurately
down to tiny power levels without switching the range. Further,
a digital LPF is used to remove unnecessary high-frequency
noise, for accurate power analysis.
All measurements, including period detection, wideband power
analysis, harmonic analysis, and waveform analysis, are digitally
processed independently and with no effect on each other. Fast
calculation processing is used to achieve a data update speed of
10 ms while maintaining maximum accuracy.

DC accuracy is indispensable
for achieving correct efficiency
For example, when measuring the eff iciency of a DC/AC
converter, not only AC accuracy but also DC accuracy are equally
important. With the PW6001, a DC measurement accuracy of
±0.02% rdg. ±0.05% f.s.* delivers correct
and stable efficiency measurements.

Filter for preventing aliasing distortion in harmonic calculations
Get a combined accuracy of
±0.07% rdg. even with current sensor
Add ±0.05% rdg. accuracy of the current sensor to the PW6001’s
basic accuracy of ±0.02% rdg. to achieve top-of-the-line accuracy
of ±0.07%. Choose from a diverse array of sensors to cover very
small currents from 10mA up to large 1000A loads.
Accuracy of efficiency is determined by AC accuracy and DC accuracy.
