Calibration weights shows you need 50 and 100 gram when I turn scale to calibrate asks for 1000 what weights do I need

Sorry. I use it to weigh yarn and spices. Haven't needed that much accuracy.

Note that when measuring grams, 0.1 grams will display as 1. So to measure 1.2 grams, the display needs to read 12.0. This was very confusing to me at first.

1 US nickle ($.05) is equal to 1 gram. This is a test I use to evaluate calibration. However, you can tare this scale to whatever container/weight you'd like.

I have calibrated my set within 4/100 of a gm.That is using 100 gm calibrating weight.Not bad..

1st you must have a standard 100g weight. You cannot do it without it. Turn on scale, wait for 0.00 Then hold down the ON button until it reads 0. It will then flash 100.00, meaning that it wants the 100g weight. Put it on a flat stable surface, then place the weight on it and wait until it stops flashing. Done!

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.

I did not have to calibrate it but I can only speak for myself. I use it to ship out first class items or 1-3 pound items. When I get a reading of 4.5 ounces, I send out package at 5 ounces. I've never had an item weigh too much. Hope that helps.

Yes it can be re-calibrated if necessary. When I do it the scaleasks for a 1000.0 g weight. I don't have any so I just check itwith the smaller weight set I have. You can buy the weighton ebay for 17 USD or so. Wish they stated this in the productdescription.Good luck.Joe

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

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." The manufacturer calls the "Accuracy" as the "Acceptable Tolerance" and it is "+/- 0.02 g."

The scale I received weighs ounces and grams only, but down to the 1/100 of each. If you can convert n.nn grams to grains, and 1/100th of a gram is sufficiently accurate, then you should be able to do what you need to do with this scale.

MaricelliGoogle http://www.awscales.com/portable-precision-scales-01-gram/217-ac-100-digital-pocket-scale and you will find all the information.If you don't want to google here is the specs for weight ranges limits for an AWS ac 100, 100g / 3.528oz / 500ct / 1543gn (Grams, Ounces, Carets and Grains)I use mine for reloading. It will zero wander a bit but re zeros easily. I'm waiting for the 100 gram test weight to calibrate (must order, not included with this scale) but it matches up with a beam scale when checked.Jim

No. It is only accurate to .01 g witch is a hundredth of a gram . And a mg is a thousandths of a gram. If you want to measure those amounts get a .001 scale

The scale comes with no weight. I added a complete calibration weight set which had the 200g weight. Even though it does not come with a weight and you need to purchase one separately, I am still impressed with the accuracy and quality of this rather affordable scale.

gn is for grains, g is grams. If you are using this scale for reloading make sure it is set to gn. You have to use grams (g) for calibrating the scale.I have found mine to be very reliable for a travel/inexpensive scale always +-1gn. As for ct I have no idea what it is for.

The maximum weight is 20 graims. Place the two supplied 10 graim weights and calibrate. If you need more accuracy buy an expensive scale. This is a great accurate scale for the price.

From the owner's manual:IX. Calibration Adjustment 1. Press the ON/OFF key to turn the scale on. 2. Press and hold the MODE key for three seconds until the display shows "CAL" then release. 3. Press the MODE key again, and the LCD will flash the first calibration weight. Place the required weight on the middle of the platform 4. The LCD will flash then flash the second required calibration weight. Place the required calibration weight on the middle of the platform. Skip this step for model ACP-500. 5. The LCD will display "PASS" and return to normal weighing mode. Calibration is complete!According to the manual, you will need both weights. From the owner's manual:IX. Calibration Adjustment 1.
