Hi,
On product at https://www.amazon.com/dp/B07B4CWKRJ/ref=as_li_tl?tag=proeng-20
how do I reset charge/discharge accumulated energy (WH) in lower right of display?
I can reset SOC gauge by holding down square button until CCC.C (empty) or FFF.F (full) shows up in Ah.
I can reset to quiescent current (zero A) by holding down triangle button until CCC.C shows up in current.
I have seen the lowercase ccc.c show up in WH, but I don’t know the exact procedure to get that. I never see that show up if I hold down ether the square or triangle button.
Is there a certain state it needs to be in – light on, wait 1 minute after clearing something, disconnect and reconnect holding a button? I just don’t know how to do it on command.

Can someone please help and let me know how to clear it?

Thanks,
Ray
