How many grams weight for mm cartridge?


I have Denon dp-45f TT with MM cartirdge. What is ideal standard weight I should start with? It came with 1.7 grams but I remember my father used to use only .5 gram for his TT. Please enlighten me...

I have setup hundreds and hundreds and hundreds of turntables and have never seen a cart that tracks at .5 grams.

You may never seen Grace F9 cartridges (F-9F, F-9L, F-9U, F-9D) tracking force range is 0.5 - 2g. I agree that 0.5 is too low, i would say 1g minimum.

I was a Grace dealer for many years and have owned several of the Grace cartridges, (actually I currently have a couple of F9E carts).  I have also setup MANY Grace carts through the years.

According to the F9 series manual which I just looked at, Grace doesn't give a range of tracking force, they recommend 1.2 grams.  So the .5 grams is not with a Grace F9 series cart...sorry.
gongli3, How does that cart sound at the manufacture's specs? If it sounds fine, why ask ? If it doesn't, try another setting.
The proper tracking vtf for any cartridge is the one that meets the design of the cartridge.  Look what the manufacturer says and consider it gospel.

stringreen, You are repeating your own gospel. You don't believe

in any standard whatever and you have your own opinion about

any adjustment issue. Courious then that you do believe in recommended

 VTF by the manufacturer. We have seen chakster specification of the recommended VTF of 0,5 -2 g for Grace F9 cartridges. I have seen many with 1,5-2,5g. Does your method imply that you start  with, say, 1,5 g, then with 1,6 g, then with 1,7, etc., till

2,5 g.? Those  are after all recommended VTF's by the manufacturer.
