Digital Stylus Tracking Force Gauge

[karma67]

I also have one like the first/second links.

I don't like it.

The weighing tray is not horizontal (on mine anyway) and sits at an angle, with low slung cartridges, the back of the cartridge hits the edge of the tray before the cantilever has settled under the weight. The stylus tip has to be at the centre of the tray for an accurate reading so its difficult to get right. I have resorted to putting a small puck of plastic in the centre of the tray and zeroing the meter and resting the stylus on top of the puck.

It works, but I'm looking at alternatives with flat trays.

Maybe this one http://www.ebay.co.uk/itm/2909503080...%3AMEBIDX%3AIT

thats a good point re the cartridge sitting on the scales,ive had that trouble with mine.

It isn't only about accuracy - it's about positioning. Weight changes dramatically with height and so you need to know what the weight is at the disk surface. Doing this with a typical Chinese device isn't easy if not impossible. I use the Clearaudio which whilst as accurate as a good Chinese device allows you to measure at disc surface.

That's another myth. The error involved in measuring the force a few mm away from the record surface, is likely to be less than the accuracy of the scales. Do the maths.

You're welcome to your opinion but having done a lot of reading and research on the topic, and having a cart with a 0.2g tolerance I like to know the actual weight at the playing surface. I have experimented and there is a difference - try it.

And you're welcome to yours.

I've always set tracking force with scales that have a low platform ie: as close to the level of a record as possible - kind of makes sense in my little head.

I too have been lead to believe that weight changes with height and so on......

Yes it does, but the change is very small. For example with a 9" arm, if the weighing platform is 6mm above the record surface, the error involved is 0.04%. So if the measured force is say 2g, the actual force will be 2.0008g. That is an error of 0.8mg. I doubt even the best stylus force gauges have an accuracy of better than 0.005g (5mg).

If that's true Barry (I'd never get my head around the physics \ maths of it ) then thanks for sharing and the insight that were not talking the big differences as we might think.

If the spod washer is rotated across the tangental radius and alined with jupiter then it relieves the affect on the flu flu la piffy differential on the stylus

Wow! Some strong juice ya sippin tonight Al

Same applies to blowing up the tyres on yer pushbike!
