Balance your platter

[Ianmac]

This topic has come to the fore in a post in the techiepedia section relating to platter ringing on a technics1200.
The solution to this ideally requires the platter balance to be checked.

It is of course a subject that covers all platters and Im wondering if anyone has done any DIY measurements of platter dynamic balance.

my brief look on the net threw up https://apps.apple.com/us/app/vibration-analysis/id817385888

Any help would be appreciated

do we know if they are balanced any way?

Im not sure about technics. There are no signs of any balancing weights or holes.
I replaced the platter danping and tried to balance on completion

I dont know what happens with other TT's and how it is best measured, thus my question.
