Hello - I have noticed an inconsistency between the phasor diagram is represented in the PM5560 and the convention used in ION series meters.
The screen capture from page 136 of the PM5560 manual shows a ACB rotation; but nowhere is it indicated as such.
Whereas; the ION7550 manual screen capture is more detailed identifying the ABC rotation.
Can someone please confirm the convention used in the PM5560? Since ACB is a standard rotation for most wiring.
Any idea why this may appear to be different ??
Or could someone please add some clarification.
Thanks!

Hi Eric,
The factory default setting for all PM5500 series meters is ABC rotation. The diagram you are referring to comes from the PF chapter, and is only shown there as an example. The intent of that diagram is not to show phase rotation, but rather to show how current leads or lags the voltage waveform, depending on the type of load (capacitive or inductive). That is why I showed only one V and I phase on the linear axis. If you want to see how phasors work in the PM5560, please refer to Chapter 4, page 125.
Hope this helps.
