Do you need to purchase calibration weights for it?

There is nothing in the instructions that you have to, I just used a unopened food package based on the listed weight, but it kept giving me error messages.

No you don't. My understanding is that it is supposed to have an internal mechanism to calibrate.

I don't think that's necessary. The scale allows you to set to "zero" so the weight of the bowl is negated. When I tested the scale for my review, I used prepackaged items in my kitchen and allowed for slight variance and I found the scale to be within reasonable tolerances. Unless you're using it for another purpose than portion control or measuring in the kitchen I think you'll be fine.

its a little finicky, sometimes it wont read this when they have obvious weight on them. Otherwise, not bad

Only a minimum amount of calibration and storage solution comes with the instrument - just enough for the initial calibration and storage. I would recommend purchasing additional solutions when I purchased the instrument. FWP

Hello, In order to calibrate the i300, you would need a 200 gram calibration weight. They can be purchased on our site for $8.90 with free shipping. Thank you. Have a great day.

I found no calibration feature. You can contact the manufacturer and they will answer your question further.

you need to calibrate with something if you want to have a scale that measures properly; 1 of the 3 scales i've bought similar to this weighed accurately from the factory; one was 1.5% off the other was 3-4% off. I was able to calibrate one of my scales using 100ml and 200ml of water; however i was able to use a scale I knew was accurate to measure that water (since it really was maybe 95ml water and 5g of plastic cup). the nickel =5g does work pretty well but it would take 100 to get 500g; i've seen a batch of nickels off quite a lot but on average in my tests they come out very close to 5.0g (example 7 nickels should be 35g and was 33.5g but by the time I got to 10 it was 49.8g or 50.1g for example). You can get a few rolls of nickels or you can just buy a 500g weight for about the same price.

I don't think there is any way to calibrate a scale with out using a known weight to adjust a scale with. Use another scale and fill a container with something that weights 100 grams with the container, then you can use that to calibrate the other scale. Then the scale is calibrated to the scale used the make the weight. If you have a calibrating weight it is a lot easier to check your scales. Hope this helps.

Mine arrived perfectly ready to go. No calibration needed. Great scale. Works perfectly for my needs and looks sleek and modern.

No you don't need to use them. We have had our scale for over 2 years and have never used them. The purpose of the weights, my understanding anyway, is for weighing objects over 350 lbs. They are used for multipliers to go beyond the 350 limit of the scales. Hope this helps

Correct, don't need the counter weights unless you need to go over 350 lbs. Best scales we ever purchased. Had 3 digitial and they all read a different weights. Have been using for a year. Correct weight every time.

Calibration certificate is a question for the manufacturer, however, you could go to a local independent certification vendor or send it to a business, such as Rice Lake who does these certifications. The scale is a rather inexpensive model ...and if I didn't need a calibration certificate, I would do my own calibration - using several other scales, and documenting the results, on a regular basis

I didn't need one... but it is always good to have to make sure you are calibrated... awesome scale!

You do not need to purchase the software. When I bought mine, the software came with it at no additional charge. I have used it, but because the scale pairs with another device that I use, I rarely use it. Instead, I use the software that my other device came with. It's a great scale, and I highly recommend it!

Mine didn't. My requirements aren't stringent (postal packages), so I just go with their cal. If you have a more stringent requirement, you should probably buy at least one other cal weight at the middle of the range you expect your specimens to fall. One more would give you a clue about linearity.

I think you only need the counterweights if you are over 400lb, which this scale is said to do. They are to add additional weight to the balance. We did not get them with our purchase, they were extras, that can be ordered if needed. You can contact the seller or manufacture and ask them. We are happy with this balance scale, you can get on it 5 or 6 times in a row, and still get the same reading, that we did not get on the number of spring scales we have had, that break so easily when bumped.

There was only one version available when I bought mine and no, it did not come with weights.

Mine is not calibrated and is way off. They expect me to find a 5 lb. weight somewhere in order to calibrate the item.

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