Goatwuss,
Good question. Don't put your stylus directly on the platform of any digital gauge. That would indeed cause the problem you noted and also another. Many scales are magnetic and/or contain magnetic materials. The strong attraction would distort your measurement and might damage your cartridge.
Use a weighing step, which holds the stylus off to one side (no magnets) and down at typical LP height (no VTA problem).
The $800 (or $350) Winds scale includes one. So does the reasonably priced scale sold by Sorasound and others. Look at the pictures. I DIY'd a step years ago to use with my $75 jeweller's scale. Took 3 minutes, cost no money, works every time.
If I were buying today I'd buy the one sold by Sorasound.
