Optrel e650 e670 e680 differences

[_JH_]

e650 has no shade level setting.

e670 has "2 shade level settings: auto or manual"

e680 has "2 shade level ranges: 5 to 9 and 9 to 13"

Can anyone enlighten me as to what that means? I had a look at an Optrel e something last year but don't remember discussing those settings.

Thanks

From what i can see..

650...adjustable from shade 9 to 13

670...adjustable from 9 to 13 and also has an automatic adjustment where it changes from 9 to 13 by itself depending on the brightness of the arc.


680....adjustable from shade 5 to 13.

Thank you. Didn't think it'd be that simple!
