What size calibration weight does it need?

Not necessary. Comes pre-calibrated. You get to pick between 4 weights: g, kg, oz, and one other that I can't remember (but description lists them all).

The scale comes pre calibrated with a certificate of calibration. However if you still want to check accuracy just use a dime or nickel.

Hi DJ, the product comes with the tool needed to calibrate. Here's a description: http://www.cdn-timeandtemp.com/article/how-recalibrate-your-thermometer

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

Thank you for your message John. I would like to direct you to Health-O-Meter to answer your question regarding the calibration process. Their Tech Support division can be reached at 800-638-3722. They can assist you regarding any questions you may have on recalibration. The scale can be used on carpet, but I would recommend placing something underneath the scale to stabilize it like a piece of plywood. Please let me know if you need any additional assistance. Thank you very much!

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

You are right. I think it's more reliable to use calibration weight. However, I did not use it since I am not a professional baker.

Does this need to be re-calibrated when you move it before you weigh yourself?

There is an option for a small L shaped scale to be shown in image captures. It is of the same style and measurement as the software user established when they calibrated the software scale. I believe it defaults to 0.1000ųm.

I didn't need to calibrate. I did test it on 3 items that I knew the exact weight of and it was right on each time.

There is no calibration to this scale. It does have a ZERO or TARE setting so you can adjust for containers. Hope this helps

To be honest I never bother calibrating mine, and things have turned out okay. I did realize that was kind of dumb so compared the known weight of an object (weighed on another, calibrated one) to the weight shown on my scale and it was close enough for my purposes (like off by 0.1 or 0.01 (can't remember if there's two points after the decimal or not)). Though you can always calibrate w a nickel or other coin w a known weight of course.

You only need the recommended paper. It comes in little packets of 10. Open the outer wrap, there is a calibration card that instructs how to load. Drop in the stack as directed. It will eject the calibration card and you'll be set to go.

The reason is greater accuracy. You may get (very small) differences in measurements by not using the weights correctly. For items under 100 you should use the 100 calibration weight; over 100 use the 200.

I personally do not use calibration weights as 100% accuracy is not required for the reason I use the scale. That being said, if one requires accuracy, I would think 3 weights would suffice. One each at the low, middle and high points of the expected range of measurement. I hope this helps you.

Its always good to have a calibration weight just in case its jarred or dropped during shipping, as this will throw the calibration way off. Or if you want, use an american dollar bill or a jefferson nickel as these will weigh 1.0 and 0.5 respectively. I own one of these, bought it about 5 months ago. Its a lot smaller than it looks but the calibration was dead on accurate despite its cheap price and small size.

I've never tried it, but have you checked with the USPS to see if they have any calibration weights on site? I'm sure their scales, like all scales, have to be calibrated regularly. You could take it to them and see what they say. I live in a rural area and the local branch is never very busy, so I'm sure they would help me. A busier location may not be as helpful.
