what size weights do you need to calibrate this unit?

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.)

I thought it could be calibrated but the web site said this ... "Only certain Escali scales can be calibrated, please see specific product specifications for more details. Most other Escali scales do not need to be calibrated, accuracy is guaranteed out of the box." The user guide (which can be downloaded as a .pdf) for the all plastic Primo doesn't mention calibration. The Website FAQ is ... http://www.escali.com/FAQ. You can always buy a calibration weight of some size less than the scale's max. capacity to VERIFY the scale's accuracy, but the scale can't be RECALIBRATED if it doesn't have that function.

Hi to zero scale use the little wheel under the round Dial. adjust it every time u use it if u need accurate daily weights

I don't recommend M. Gonzalez' solution. I calibrated to 1000g. My 500g weight then says 667g. Calibration is not linear.

I contacted the company before i bought the 3000g and you do in fact need a 2kg calibration weight

No does not require calibration. I compared with another scale and it was accurate.

Yes it can be re-calibrated if necessary. When I do it the scaleasks for a 1000.0 g weight. I don't have any so I just check itwith the smaller weight set I have. You can buy the weighton ebay for 17 USD or so. Wish they stated this in the productdescription.Good luck.Joe

Yes you will need to purchase weights. Dimensions are available on the manufacturers website.

I did not have to calibrate it but I can only speak for myself. I use it to ship out first class items or 1-3 pound items. When I get a reading of 4.5 ounces, I send out package at 5 ounces. I've never had an item weigh too much. Hope that helps.

No it doesn't come with a weight for calibration. I use a US coin to help me calibrate. You really don't need one for this scale.

Lol.I haven't tried yet. As I stated,mine is off by 10lbs. I guess check on line and see if they have instructions on how to calibrate. Good luck

I do not need a calibration weight, It came in perfect calibration. A penny is 2.5

No Problems, If you adjust the small screw on the left of scale, you will get a proper weight. took me about 20 minutes to get it set right.

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.

There is a button on the bottom of the scale towards the front. Just push it until you get the desired unit if measurement. Hope this helps :)

In my humble opinion, what you did wrong was to buy this product. The one I received was so poor that I can guess at the weight more accurately. Send it back before it is too late.

I purchased this scale as a teaching tool. Since receiving your question I have been using calibrated weights to check accuracy and it has been spot on. I have also rigged an apparatus that allows us to weigh odd shaped items such as a flake of hay and I have found this scale to very handy in the barn. I do not know how to calibrate it and it is clearly marked "not legal for trade" I hope this is useful.

I received model ACPro-200. It only required the 200 calibration weight. The calibration process never asked for the 100 calibration weight. I noticed in the reviews that AWS must have updated their hardware sometime in 2015, as many of those reviewers also state that their system never asked for the 100 calibration weight, only the 200. Save $5 and skip the 100 calibration weight.
