Electronic stylus force gauge question


I recently bought my first electronic stylus force gauge. It's a generic type made in China, but looks and feels a surprisingly decent quality. It was purchased from Mehran at SoraSound for those who happen to have it.

I noticed that when I try to measure the VTF, the gauge begins to display a minus reading of -0.01-03 g as I'm lowering the tonearm to place the stylus on the black dot. It then displays a steady reading once the stylus is placed on the dot, which appears to be accurate by comparing with the Shure gauge I used in the past.

I make sure that the platter is secured so I'm not quite sure why the gauge displays the minus reading before the stylus lands in the measuring spot.

Has anyone else experienced this with their electronic gauge? I realize the minus value is arguably negligible, and the issue might be of no practical significance, but I'm trying to get my Delos to track as close to 1.75 as possible so I wonder whether I need to adjust for the minus value. I'm also curious why this is happening.

Stringreen,
It's evident from several recent threads that Actusreus is not yet comfortable with trusting his ears and prefers the security of measurements, even measurements that don't necessarily correlate to optimal sonics. If he believes that every Lyra is so free of sample deviations that precisely 1.75g of downforce is optimal, well, Jonathon Carr himself would tell him otherwise but we all have our own way of enjoying this silly hobby. It certainly won't do any harm to play at that downforce. ;-)

Actusreus,
I tried one of those scales and it was strongly affected by magnetics, so much so that I regard it as unfit for the purpose for which it is sold. Additionally, ANY scale that resolves to .01g or better will respond to the slightest changes in air currents. I can alter the reading on my scale (different brand, same resolution) by waving my hand over it. Try moving verrrrrry slowly... and hold your breath. Seriously.

You don't need a $250 scale, unless you insist on one with an audiophile logo. My My-Weigh MX-50 cost <$99. With the addition of a DIY weighing step it works just fine, certainly far better than the one you originally described.
Pradeep,

A scale that resolves to .1g is okay. If it displays 1.7 then you're somewhere between 1.65000 and 1.74999... That's close enough to begin tweaking by ear. My scale resolves to .01g but I rarely pay attention to the second digit.
My apologies if my post came across as patronizing. I did attempt (not so successfully) to acknowledge what you just said, that, "Many of us just want to set our system up and listen to music, not tweak it for every record."

The last bit of my post that you quoted spoke to that, "..we all have our own way of enjoying this silly hobby. It certainly won't do any harm to play at that downforce."

Bingo on the gift of sensitive hearing also being a curse. We have had to walk out of restaurants because the piped in music was insufferable. Fifty years ago my mother used to leave the room when certain popular vocalists came on the radio or TV. My father would happily listen while she was stuffing cotton in her ears. (I've heard those vocalists again recently, on those TV promo ads for oldies collections... Paul and I run and hide with my mom, lol.) We don't tweak because we want to, we tweak because we have to.

Again, my apologies for belaboring a point that was not what you were asking.
Moonglum,

Your assumption that, "Actus is experienced enough to know whether he needs to go plus or minus 1/100th of a gram", is belied by his own words. He clearly stated that he has no intention of doing so. I often find it helpful to read what people actually say before making assumptions on their behalf.

By way of clarification, no one has been "heckled". Heckling involves gibes or challenges offered with the intent to disrupt, upset or goad. The intent of all comments on this thread has been educational. A debate of ideas and practices does not constitute heckling.

Thanks for your input,
Doug
