The WT5000 is the world’s most accurate precision power analyzer with a basic power accuracy of ±0.03%. Its accuracy specifications are guaranteed from 1% to 130% of the selected voltage and current ranges. With minimum influence of low power factor (0.02% of apparent power) the unit is also accurate at large phase shifts and frequencies.

• AC power accuracy: 0.01% of reading + 0.02% of range
• DC power accuracy: 0.02% of reading + 0.05% of range
• 10 MS/s 18 bit ADC
