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.

We calibrated the LOW end of our scale using a US nickel coin, relatively new. As minted, they weigh 5.00 grams at sea level. A cent "weighs" 2.5 grams. Since the resolution of this scale is 2 grams, we found that a nickel registered 6 grams, while 2 cents registered 4 grams. To me, that's accurate, because it splits the knife edge at 5 grams (which it will not display because of its resolution). I suppose you could go to the bank and get $63.50 in "pennies". That should "weigh" 15875 grams, or just .7 grams light of 35 pounds.

You may also want to ask the postal employee if the lobby scale is calibrated. Often the one in the lobby may read differently from the one at the desk (surprised to discover one day!)

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

There's no way. It's supposed to be auto calibrated. Mine was always off by 20 to 30 pounds. Never the same amount, though. Worst scale ever.

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

Just re-weighed everything, with the product box -- the box with all the printed info on it, the one you'd see on the shelf in a retail store (not the shipping box; I don't have that anymore). Comes to 4 lb. 9.75 oz., which is 4.61 lb. (since there are 16 oz per pound). The product details section of the Amazon listing says that the shipping weight is 4.2 pounds. So, if anything, it looks like the seller is charging *less* than the actual weight...

What do you mean by updating? Did you mean updating the shipping rates? The scale weighs the item but it does not give an actual shipping cost. You would need to enter the weight online at the USPS website to find the shipping rate. I really like having a scale like this to weigh my items.

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.

You can order calibration weight at AMAZON.com. They have various sizes of weight to choose from.

Did not come with weight. Scale must be calibrated. Suggest amazon search 200g weight

weigh something on which is printed from a manufacturer the weight as a known..... repeated times. Then decide. I am using mine for portion control by weight... and just take the first reading and be done with it. However, if you are doing measuring for packaging or other, perhaps the scale has issues and should be returned.

I also use this scale for weighing small packages and find it super easy and very accurate. It is so easy to weigh your package at home, plug the info in to the USPS website and print shipping labels right from home! Selling stuff on Ebay is so easy now, takes the guesswork out of the postage fees and makes shipping things fast and easy!As others have said, though, if you have very large or odd shaped packages, I don't know if this scale would be recommended. And the weight capacity is only up to 11 pounds.

Calibrate, meaning to get it back to 0? I put the item I want to hold the food such as a paper plate or a bowl/cup on the scale, push the "tare" button and it will reset to zero. Then I add the item/food I want to measure the weight of.

300g. The sticker is wrong. Follow the instructions to calibrate it then whatever weight it says on the LCD readout is the weight you need to use. I've had 5 or 6 of this same one now, I love it.

I have always taken to lowest value. Most persons that calibrate say not to leave at any set point. Then again if you want precision the lab where I worked at required calibration every year with cal certification papers. Bottom left is your answer. http://www.snaponindustrialbrands.com/dsn/wwwsnaponindustrialbrandscom/Content/PDF/CDI%20Click%20Wrench,%20Plastic%20Handle%20Operation%20Manual.pdf At lowest value which would be 30 ft/lb

The scale comes with no weight. I added a complete calibration weight set which had the 200g weight. Even though it does not come with a weight and you need to purchase one separately, I am still impressed with the accuracy and quality of this rather affordable scale.

The box says grams but the scale says pounds. It does NOT give you weight in grams. You must pay return shipping if this scale if it's not right 4 U
