Thank you for the comment!
If factory calibration cannot be executed by user I think it should be removed from the settings.
Can you advice how should I do the factory reset so my readings will be right after I change the clamps to the right phase?
Should I first change the clamps to the correct phase (measurements will be off) and then do a factory reset?
Is there a way to import my saved data after factory reset so I won't lose all previous readings?
My issue is why I think calibration is needed that at set-up clamp A was attached to phase 3 and clamp C attached to phase 1.
I wanted to change the clamps to the right phase but then the readings are off. I also tried turn off phase 1 breaker then Shelly also does not read anything on phase 3 with clamp C as well. Phase 2 with clamp B is still working.
Now I changed back clamp A to phase 3 and clamp C to phase 1 and readings are OK again.
How should I change the clamps to the right phase?
Maybe factory reset would solve the issue? But I'd like to avoid it if possible not to lose my data.
Hi,
I tried to do a factory calibration for the transformers. The option is under transformer calibration but when I press it I have only an error message.
What is the right way of doing factory calibration?
