Which VTF Scale are you using?

+1 on Ortofon DS 3 digital scale. Utmost accuracy and reliability.

Btw, the link I posted above from the Ortofon site includes VAT ca 20% which is removed when shipped out of EU.

@mijostyn. Thanks for pointing this out, However my scale is clearly marked "Made in Japan." I have tried multiple Chinese products that were inexpensive, but all were inaccurate and risked to damage my cartridges or the TT was not tuned right. I only use two scales. The Ortofon I recommended earlier and an old version of the Clear Audio digital scale, which I bought 20 years ago and still works fine. Both are tested for accuracy often and they have never let me down. My two cents.
