Tracking Force Gauges


I have only coarsely adjusted VTF on my cartridge using a Shure gauge and taking into account the ~ 0.3g overshoot some have reported.

I would like to embark on a careful study of the sensitivity of the sound attributes to small deviations within the recommended mfg's range. I'm curious to know what high VTF sounds like compared to low VTF and to find an optimum setting.

To do this I'm interested in your recommendations on digital VTF gauges with 0.01g accuracy.

I've heard about the MyWeigh scale and others. It seems like the my weigh scale is a traditional looking digital scale in that the measuring platform is very wide with the load cell likley centered beneath the platform. I'm not sure that one gets repeatable and accurate results if the cartridge were to be placed near the edge of the platform if the arm can't be moved in such a way.

Any thoughts on accurate VTF measurements?

Hey fellas,an interesting point,and something I can look forward to "scoping out".......Since my circuit breaker box was damaged in the lightning strike(eluding my audio room,thankfully),the electrician doing the new work,and providing a far better "box",claims my current to my electronics was severly limited,by the old unit.He claims I will receive a far better current delivery,and sound, with my new box(I hope).
Also,Jeff Rowland claims(I hope all these claims are a "little bit" accurate)the new power supply circuitry he has given me is far more advanced,and reliable than the old(only two yrs)one.He also claims it cost him a small fortune,yet since I was such a good sport,for waiting without "kvetching",there is NO charge.What a nice guy!
He was,also,in a severe motorcycle accident,but is thankfully fine.I cannot stand by and let him bear this expense without some kind of action,on my part,so I have decided to offer his company some free printing.It seems like the right thing to do,even though I was under warranty.
BTW--I will be enjoying the upcoming TV season in "wide screen Hi Def".I think my family deserves some fun,as the last few weeks have been horrible,and we'd like to put it behind us.
As for my tennis game...It seems like I will be on permanent leave,there,as my epidermal layer(on my palms,and finger tips) has still not healed.My Dr claims this was from all the stress,yet I thought I was handling everything quite well,but this "hands crap" really sucks.Imagine brushing your tweeth in pain.I don't have to go anywhere else,with this.Use your imagination.
Though I will still set-up my pal's Tranny Orpheus,only will be wearing cotton gloves.

Based on my schedule,and desperately in need of a nice vacation,I may wind up going to the RAF!!BOY,would I love that.I'll bet my hands would clear up,too!

Best!!
Aoliviero -- I experience the same with the 95 gauge and I usually tare it by holding the cartridge to the nearest point before the stylus touches the surface. This, hopefully, helps to eliminate any magnetic attraction, if there is any, and hence allow the "near" absolute VTF to be measured with that particular cartridge. With this, I also discovered different "negative" values in the readings after taring the scale for different cartridges. I suppose it is due to the strength and design of the magnet in these cartridges.
Vincentkkho,

The more I thought about this the more I think I need to retract my assertion on a false reading as a result of the magnetic attraction. Certainly with the cartridge suspended over the gauge, one sees a negative reading appear. However, when the stylus touches down and makes contact and the arm is free to move, I think there is no upward force and the gauge is truly reading the VTF. What do others think?
