Yes I get that same drift just when it sits still, and it's around 0.004g. It's really annoying, considering that with the 2C's or 5-meo DMT, 2mg can make all the difference.
I wonder if it's more accurate within certain ranges? Perhaps above 4 or 5 grams it's better. If I can find a 5 gram weight to stick on there along with the powder then I'll check it out.
I guess I should invest in some 0.001g scales but it's a lot of money. The 1210 cost me 185 quid and I've not used it all that much.

After calibrating it I always weigh a capsule and use it to hold whatever I'm weighing. I just add my desired weight of material to the capsule weight. The gelcaps I've been working with are pretty much all 94mg. I've had a few in the batch that were 92mg. So I just add my chemical weight to that.
Anyway, I tried putting the 20g callibration weight back on after callibrating and removing it and I still get the drift. Only now it's like 19.996g-20.004g

This is weighing the callibration weight with the wind shield closed, on a steady oak desk. And the scale has been in the room (at the same temp and humidty) for months. So I don't think the drift has anything to do with weighing a small amount and therefore don't think adding a 4-5gm weight will help you. However, I do believe they are more accurate when weighing slighly more than just a few milligrams. So that's why I always use a capsule as part of what I'm weighing. It adds almost 100mg to the weight.
I've been looking at other scales and it's getting really tempting to get out the damn VISA and just buy something with 0.2mg precision. I really hate to drop the cash, but I found a Sartorius GC-503 on the web for $899 that looks absolutely SWEET. Maybe there are other balances less expensive and with similar precision? Of course I'll probably just be buying something that drifts in 0.2mg increments instead of 2mg increments, but I can live with that.
I used to be very comfortable with my Tanita, but at some point in time I plan on working with 5-MeO-DMT and 5-MeO-AMT, so I don't think using a scale with 2mg precision and having a 6mg drift is acceptable with these chemicals. If it doesn't start behaving better, it will need to be replaced. I've also been pushing the dose range to my upper limit with things such as 4-Aco-MiPT and 4-OH-MiPT and I don't need an extra 6mg more than I planned on taking of substances like these either. I had a VERY difficult 4-AcO-MiPT experience this past weekend.
If I were weighing out what were a low dose for me and it ended up being 6mg more, fine. I can handle that. However, when I'm weighing out a dose that I know from previous experience will result in a difficult trip, I need it to be precise. I at least expect 2mg accuracy. I realize that with +-2mg, that's a 4mg variance already. I don't need this 'drift' adding to the variance.
The Sartorius I'm looking at is really sweet, but a storage case for it is like an additional $345. So I'll pass on the stoarge case, but the thing looks like an analytical balance from my college chemistry classes and is huge. So it's not something I would think you would move around alot and I would probably have to leave it set up in my office. Just looks kind of suspicious having a scale that expensive and not being a jewler. 8)
That's one nice thing about the Tanita is it's small enough to put away when you're done using it. Shit, I'm just dreaming. It will be a hard decision to actually shell out that kind of cash for a scale. I mean, do you know how many whippets I could buy for $899?
