Hidden digit

[i-B4se]

Hello,
I've been using this for a long time and it works perfectly, but we replaced the meter last year and one of the numbers is covered by a strange design-related part, meaning it can't recognize the number.
Can you set a number at a certain point so that it only registers the others?

Thank you in advance

It looks like you can twist this needle and it only serves to remove the bubbles or push them to an area where they won't bother you.
