I just got my Iotawatt today but forgot to add the AC reference to my cart. I’ve ordered one, so it will be here in a few days hopefully, but in the meantime, can I start installing components, testing connections, etc., without hurting anything? I have a very rudimentary understanding of electrical engineering, so my thoughts are that I’ll either not get readings at all, or they would be inaccurate, but just want to double check that. Thanks.
It will not work reliably without the AC reference.
