Re: PDP Reading Incorrectly over CAN

Unfortunately, the PRO user manual doesn't state any expectations for reading channel current.

I would guess that, in this case, this current sensor is essentially floating, which means the value it returns is meaningless. Try putting a breaker in the channels that are reading incorrect and let us know if they are still incorrect. Then try hooking up a low-current device to the channels and see if they still read incorrect. It's just a guess, but I think putting a breaker in will be enough to stabilize the current sensor and give you the expected result.
