What is the accuracy of the phase angle measurement on the ION 7650?

The Power Harmonics Module has phase angle accuracy within (±0.5º x harmonic number); hence, the deviation may increase with higher harmonics. In addition, the Power Harmonics Module is limited to a 2 second update rate since the module is driven from the FFT modules, which have a 2 second update time.
