Is calibration mandatory? What weights do you need?

The scale has automatic calibration. This scale does not appear to be NTEP approved, meaning it is not the type of scale that is legal for trade.

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

Hiyou will need both weights to calibrate this scale (200gram and 500grams). I have a set of labotory weights, so I am able to varify this scales accuracy. I use it daily. It has never been off by more then 0.03grams. Not bad for a 500g x 0.01g scale which cost me less then twenty dollars. I spent around two hundred for my weights alone.I think you will like this scale. P.S. When my scale arrived it was. accurate plus or minus 0.02grams.good luck, have fun. George D. 3-6-14 3:21pm

I have always taken to lowest value. Most persons that calibrate say not to leave at any set point. Then again if you want precision the lab where I worked at required calibration every year with cal certification papers. Bottom left is your answer. http://www.snaponindustrialbrands.com/dsn/wwwsnaponindustrialbrandscom/Content/PDF/CDI%20Click%20Wrench,%20Plastic%20Handle%20Operation%20Manual.pdf At lowest value which would be 30 ft/lb

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.

It was not needed. It fired right up for me, with no problems. I compared weights carefully with objects to a dietary scale that is very accurate that I have. It's been a great scale!

I didn't need to calibrate. I did test it on 3 items that I knew the exact weight of and it was right on each time.

I do not believe this unit required calibration. I checked it against some 1 to 4 oz letters I had and it registered correctly. I have used this for up to 13 oz, including flats, and have sent a lot of mail using it. So far, no issues. Good unit for the price.

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.

Its always good to have a calibration weight just in case its jarred or dropped during shipping, as this will throw the calibration way off. Or if you want, use an american dollar bill or a jefferson nickel as these will weigh 1.0 and 0.5 respectively. I own one of these, bought it about 5 months ago. Its a lot smaller than it looks but the calibration was dead on accurate despite its cheap price and small size.

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.

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.

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

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.
