What size weight do I need to calibrate the 3000g one?

I contacted the company before i bought the 3000g and you do in fact need a 2kg calibration weight

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

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.

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.

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."

I routinely measure 0.04 grams, works for me but I have no way to compare. The calibration seems right on.

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

Get the calibration weights. They are an absolute MUST with inexpensive scales. This one is pretty accurate. I reweighed the same mass 5 times and got the same reading each time.

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).

If you look at the face of the scale it says it weighs to 100g (grams). It is strange that it would calibrate at the far end of its range though rather than somewhere near the middle.

I used a tape measure... Weight isn't always accurate; I've found. Build/measurement is more important.

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.

I had the same issue. I purchased the weights to properly calibrate but still nothing. In my honest opinion, this scale is trash. Sorry

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

Hello. I believe that 10 in-Lb. is the lowest setting and the calibration chart that was sent along with my unit stated that at 10 in-lb. it registered 10.85. 30 in-lb. setting calibrated at 29.90 and 60 in-lb. it registered 60.40 Hope that is of help to you.

Arla's answer is great. I would just add that the weight has a couple of numbers to notice. If you're at 1000 ft in elevation or less, use the 10 port on the weight. 15 if your above 1000 ft. The gauge is nice for reference but there's a lot of things that could happen to the gauge to make it lose it's calibration. The weight calibration will likely outlive you. The popoff is a safety valve that blows at 20 psi. Not a good idea to make a practice of blowing it's top. You might consider buying an extra to replace each year and the steam port used for the weight every couple of years if you're making good use of the cooker. Arla's answer is great.

This scale reads to .01 grams. If you have something that weighs 3.7 grams exactly it will read 3.70. One thing to note is that scales of this sensitivity need calibration to be accurate. This scale can self calibrate if you have a 100g weight I believe.
