where do I get the calibration weight?

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

It came calibrated but I also had an old school fool scale that I used to verify the digital scale was correct. There is also an instruction manual.

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.

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.

Hi Christa, To calibrate the scale: Press "MODE" and "ON/OFF" at the same time to turn on the scale and release the keys until the LCD shows ISN. When ISN is stable, press "ON/OFF", the LCD will show "30lb". Then put a 30 lb weight set unto the scale and press "ON/OFF" again. LCD shows "PASS", the calibration is finished.

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.

call customer service # in your book, sounds like you need to re calibrate it. LOL Get ready take to a gym, you need like 300 lbs of weight to calibrate.

It did not need calibration although I did check to make sure it was correct when I received it. I have owned it for over a year now and I keep it turned off when not using it so the batteries are still strong. I did not buy an adapter. I truly love mine. As I get older, it gets harder and harder to see, so having the weight displayed right up close is wonderful. I don't think you will be disappointed.

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.

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.

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.

I purchased a 100g calibration weight which I use once every month to ensure that the unit is measuring accurately. Since this is not a high end scale, I would recommend doing it.

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

The manufacturer calls the "Accuracy" as the "Acceptable Tolerance" and it is "+/- 0.02 g." Exactly the same calibration standard weight doesn't always read the same number (measurement repeatability). But my 100-gram calibration weight has always read within this "+/- 0.02 g" accuracy. I've found that the "sensitivity", or the "minimum measurable weight", is about 0.03 gram. There is some hysteresis effect to it. That is, after you measured 0.05 gram, then you can reduce the weight to the minimum 0.03 gram. You can't directly measure the 0.03 gram weight without adding some additional weight first, then take away the additional weight. The "reading resolution", or the "Readability" as called by the manufacturer, is, of course, "0.01g."

Its always best to calibrate to a known weight. I did not have any known weights, so I calibrated it to zero (ie no weight). For my purposes, this was sufficient.

First, remove the batteries and then reinsert. Put scale on a hard, flat surface. Step on the scale for just a moment, release, and then let the scale reset to 0.0. Do this a couple of times. Let the scale auto-shut off. Now try to step on and see if you get a reasonable weight reading.

During the calibration procedure it only asked for the 200 gram weight, not the 100 gram one, so I don't know what others are talking about. BTW, I spent a bunch of time calibrating this down to .01, only to realize that it will vary depending where on the scale platform you place the idem being weighed, so it's kind of a waste of time.
