Right -- I am thinking of switching my current AT95E (which tracks at two grams and above on most systems; I'm running it at 2.3) out for the AT440MLa/b equivalent (which will track around 1.5 to 1.7 grams from all accounts). So I'm going to fit the headshell to the arm and then drop my counterweight to around "1.5" or so to begin taking readings for the new cart...this way no damage can be accidentally done.
On a couple of decks that I've got, the Technics SL 1500 is absolutely spot on with the balance and set routine, but my SME 3009 series 2 improved is a bit heavy. It's a bit odd that yours is so inaccurate. How wrong was it? Was it too light or too heavy?
To be honest, I don't remember what the weight read because it was some time ago...but some turntables are NOTORIOUS for being off on their counterweights out of the box; the AT-LP120-USB is one of them, depending on what a buyer gets in terms of stock.
Did you ever Google inaccurate counterweights on turntables, or some such combination of keywords? There is an almost overwhelming number of discussions on this, and how turntable owners should trust a scale or some kind, whether analog or digital, rather than their counterweight markings.
I don't think that you're going to get a definitive yes/no on your original question though. There is no reason to go through the whole balance routine when using digital scales, other than the reasons I mentioned, ie not to put too much weight through the assembly by accident.
Well, that's a kind of definitive answer right there -- that there's NO reason to re-balance the arm if using a digital scale.
