what is the accuracy tolerance of the scales and what size calibration weight does it require?

0.01g & you can check w/1-5gram wt but the tare should be sufficient. If not accurate return or refer to manufacture.

Not sure what you mean by accuracy tolerance but it is accurate to .01g as for the calibration weight you need 200g. As for overall tolerance I find it to be kind of flimsy and it is noticibly larger than a zippo.

scale will measure accurately to less than 1/10 mg. as scale is sensitive do not use in drafty areas.

The manufacturer calls the "Accuracy" as the "Acceptable Tolerance" and it is "+/- 0.02 g." Exactly the same calibration standard weight doesn't always read the same number (measurement repeatability). But my 100-gram calibration weight has always read within this "+/- 0.02 g" accuracy. I've found that the "sensitivity", or the "minimum measurable weight", is about 0.03 gram. There is some hysteresis effect to it. That is, after you measured 0.05 gram, then you can reduce the weight to the minimum 0.03 gram. You can't directly measure the 0.03 gram weight without adding some additional weight first, then take away the additional weight.

Seems to be consistent. As far as accuracy goes I can't say. Certain scales weigh me heavier, others lighter.

The calibration weight may vary by the model of the scale. Mine is a Blade - 1KG. It uses a 500g calibration weight. Look in your owners manual. If yours specifies 500 and it's "asking" for 1000, it may be defective.

It appears that calibration is not required on all of the scales. However, even trying to calibrate the scale still didn't work for me. I did like the fact that it had a bowl on top and the proposed functionality but I wasn't able to get that far.

No, you do not have to calibrate this scale. It work great just out of the box. I highly recommend it!

kg and pounds / inch and cmawesome scale - accurate to 1/8 poundWorth what I paid for it!

Calibration is not possible to the best of my knowledge. I have found it to be accurate + or - 1 or 2 grams and I think that is more a sensitivity issue (placement, etc). Hope this helps. As noted above - "tare" is certainly possible if that is what you meant.

During the calibration procedure it only asked for the 200 gram weight, not the 100 gram one, so I don't know what others are talking about. BTW, I spent a bunch of time calibrating this down to .01, only to realize that it will vary depending where on the scale platform you place the idem being weighed, so it's kind of a waste of time.

The scale must be calibrated for accuracy. Directions are provided in the user's guide to calibrate the machine.

I'm pretty sure there's no way to recalibrate it. If there is, it isn't mentioned in the manual. Basically, Escali is saying that some of their scales have a calibration feature (I don't think this model does though). For the scales without a calibration feature, you could buy a reference weight to see how accurate the scale is (that's a weight that is guaranteed to weigh a certain amount, within a specified tolerance), but after you figured that out, there's no way to calibrate the scale to correct for the discrepancy. (For the record, mine has been plenty accurate for anything I've used it for. I haven't used a reference weight to check its accuracy or anything, but I haven't ran into any recipes that needed a super-high degree of accuracy anyway.)

copy this : weighmax 2822-75lb postal shipping scale calibration - into your google search window, & read the manufacture's PDF. You will also see a youtube link appear with your search results, & it covers calibration. I already posted some advice on what to use as a calibration weight ( if you need info on that ). Mine needed no calibration to begin with, & still has no calibration issues.

Sorry. I use it to weigh yarn and spices. Haven't needed that much accuracy.

Hello. I believe that 10 in-Lb. is the lowest setting and the calibration chart that was sent along with my unit stated that at 10 in-lb. it registered 10.85. 30 in-lb. setting calibrated at 29.90 and 60 in-lb. it registered 60.40 Hope that is of help to you.

We have been using the scale 4 months, we have not calibrated it. We used it right out of the box, just make sure to use, on a level flat surface.
