Tracking Force?


I have a Clearaudio Concept turntable (about 7-8 months now). Beautiful piece of work. It was bought already factory  setup. In 50years of buying records I have only had three turntables and never really bothered too much about doing my own setups.
Last week I bought digital scales for measuring tracking force.
In the Technical details in the manual it states Tracking Force as 2.2 g(+/- 0.2g)
When I placed the scale on platter and lowered the tonearm it read out 3.8.
My thoughts now are: should I alter, that is, tamper with this?  OR Should I trust and go with the factory setup?

First, confirm that your tracking force gauge is non-ferrous (with a magnet). If it is, your arms counterweight must have moved during packing, shipping, or unpacking. Readjust your counterweight to achieve correct VTF.
Anyone with a cartridge required to track greater than 2.0 g in this day and age should have his/her head examined

Can you please explain that? I have a Clearaudio Concerto V2. All their cartridges in that range and up have a 2.8 gr. recommended tracking force, which is what I use based on listening tests. I've used it for years and it sounds fantastic. Would like to know what it is that you know better than Clearaudio.
Thanks everyone for your input. (Well, nearly everyone) It has helped me to plan ahead.
My cartridge at the present is the basic Clearaudio Concept. For the last 20 years I have had Grado's, the last being a wood body Reference.
I find this Clearaudio Concept to be very "bright" by comparison. That is what moved me to buy the scales to check it out, I just assumed Clearaudio would have it right.
dwette69, have you had experience with sound of other Clearaudio? Would you describe the Concerto V2 as "bright"?
vino, far as I can tell the Clearaudio is not only a bright cartridge, but bright everything else. Worst waste of money I ever heard, same setup you have, only I add blame to Definitive Audio. Whatever. Maybe you will like it. My bet is you will like a Grado a lot better. I know I would.

To answer your question and correct gaps posted above-

Correct VTF matters because if you look closely as you lower the cartridge you will notice the cantilever angle changes as the weight of the cartridge presses down. What you don't see is at the other end inside the cartridge, as the stylus end goes up the inside end goes down. The end where the coils are. The coils that must be centered within the magnetic field produced by the fixed magnets. So if you hear anyone saying VTF shouldn't be such and such, they have no clue what they are talking about. The manufacturer knows how much force is needed to put the coil where they want it. You set to that force. Period.

Now within that narrow range of in your case .2 g then yes you can tweak a bit by ear. Although what you will be doing mostly is trying to get the sound you want. Which you should rather be doing by buying the correct cartridge instead. 

So now what are the challenges with making sure you're setting VTF accurately? Well first you zero and tare your scale by using whatever known weight it comes with. Next you check to see if when the stylus is resting on the scale it is the exact same level as when playing a record. Most scales are thicker than a record so you can't just set it on the platter or the cartridge will be too high. The arm will be high and whatever VTF you get will be different when playing a record. Only way around this is make a little stand, block of wood or whatever, so the scale is exactly at record level. Then you lower the stylus precisely to the center of the scale. Whatever reading you get you raise and lower and repeat until you are sure you are consistently in the middle of that 0.2 g range.

All this of course is assuming the overhang was done correctly. Being they were so far off on VTF that is not an assumption I would make. Trust but verify, as they say.
