I am trying to tune a duplexer and when I either move to or away from the next line on the scale, the graticule moves up or down or bounces around. This is very annoying and makes it difficult for trying to tune. Is there a way to keep the graticule in one place and not move around???

Beware of cheap underperforming clones
As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

I set both scales to the same amount of display at 15 db then i use a
old ball point pen as a stylus to move my points.
If you are in Billings some time we can go over it.
