Does this come with calibration weights? Are two weights recommended? What weight?

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.

No it does not come with a weight. It needs a 500g weight. Only one is needed.Source: http://www.americanweigh.com/product_info.php?products_id=586

No, it doesn't come with weights. You'll want to buy some 10's and 5's and just try it out and see what balances it. Start with 10, then add more weight as needed.

The AC-100 uses two (2) AAA batteries. Do not forget to order the calibration weight, especially if you plan to measure items smaller than 1 gram.

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.

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 am not sure what you mean by calibrate, but it may require some adjustment to be perfectly sighted in at your desired distance. It includes tools for making the adjustments and some rudimentary instructions.

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.

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.

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

Hi DJ, the product comes with the tool needed to calibrate. Here's a description: http://www.cdn-timeandtemp.com/article/how-recalibrate-your-thermometer

I checked the users guide and do not see any information about calibration of the unit. There is a support number you can call.

The reason is greater accuracy. You may get (very small) differences in measurements by not using the weights correctly. For items under 100 you should use the 100 calibration weight; over 100 use the 200.

It self calibrated when I first set it up. I have moved it twice since then with no problems.

The meter does not come with calibration solution, this is something you would have to purchase separately. The instructions for calibration are in the manual.

It comes with the weights. Mine was missing one of them when it came in and I contacted the company. They sent me another weight and a couple of spares.

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