Do i need to buy the calibration weight?

Highly recommended, I knew we should calibrate it before using it so I did buy the 500gr calibrator ando I found it to be essensial, otherwise it Will not be really accurate

That's not a yes or no answer. It depends on what you need it for. I wanted to measure out and mix exact amounts of dry plant fertilizer to reconstitute with water and store in bottles for my aquarium.

You should. It's calibrated from the factory but you won't know how long it's sat in some warehouse. If you care about getting the most from what you're weighing than definitely get the calibration weight.

If by calibrating you mean bringing the scale at 0 when you place on it the container in which you wish to weigh something, there is a button that calibrates the scale at its touch. It's user friendly...

Yes. It allows you to set up the container and reset it to zero. Then you can have an accurate weight.

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

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.

I guess by using a known value, like the calibrations buffers, 4.0 or 7.0. It's like using a calibrated weight to check a scale

I do not use a calibration weight since I am using my scale for espresso. I am just interested in repeatability, not the exact weight. The others made great suggestions on using coins.

I just got mine today and also a 500g calibration weight. My understanding from other blogs if your scale is a max 1000g then you need 1000g weight to calibrate it. What I did was use my 500g weight as a reference then got a 16.9 fl oz water bottle, opened it up and sucked out the water with a syringe until the number was the exact same as my calibration weight. Then used both the weight and water to re calibrate. Works just fine now.

Short answer is yes. The software will 'remind' you to calibrate after a month or so. It's good to regularly calibrate as monitors and settings can change over time. This is especially important if your work requires a calibrated monitor for print/video.

Mine did not come with a calibration weight. Whether you need a calibration weight, depends on your use for it. I make coffee in the morning with it and measure out the grams of coffee I want as well as the oz of water I need for it. I trust it has been pre calibrated correctly. But then again I'm only making coffee.

It does not require calibration, but it sometimes under-weighs by .1 ounce. I bought a set of 1 oz and 2 oz weights and test it occasionally, especially when I get a reading that is exactly 1, 2, or 3 ounces.

It comes with maybe a ketchup packet worth of calibration solution which will calibrate initially. You can go about a month without calibrating. It falls off a point or 2 by then.

No this scale is too small for packages. Also regardless of the scale you decide to buy make sure you buy the tools for calibration such as the weight units

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

I only use this scale at my farmers market to weigh produce. I believe you have to get a special scale to get what you want as far as calibration. I know there out there. I would google scales with calibration and that should take you to a company, but expect to spend quite a bit.

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.

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.
