Anyone who wants a NIST traceable set should know that they aren't going to get one for $13.
It measures about 1 3/4 inches in diameter and 1 1/2 inches in height, not including the 3/4-inch-high grip in the center.
I'm not sure what "handles" you're talking about. I'm sure the pick-up knobs on the top of each weight are factored into the calibration. Each one's overall weight would be affected if they were removed. They're there to help you with your tweezers as you handle each weight. Because handling the weights with your hands can degrade the precise calibration of each weight over time, I've never attempted to change the individual weights by removing these, as this would compromise their accuracy.
When calibrating a scale, use a weight that is 1/2 of the scale's maximum capacity. After you've calibrated the scale by verifying or adjusting the load cells, you'll place the varying weights one at a time to confirm accuracy over a wider range of test weights. Then, using a combination of the various test weights, determine whether or not your scale calibration is accurate. calibrate at a weight of 1,000 grams; Check 10g after that. Check the scales' readings the 20g, and finally make certain Then, for each weight combination, test for consistent accuracy across the entire range until you're satisfied with accuracy or determine if it's necessary to adjust the weights. how much your scale fluctuates within a given range if you want to test to the full extent of your abilities Purchase a new set of calibration weights if you need to cover the entire upper range. Isn't it simple?

While reading the following review, keep in mind the price of this item. Using a Radwag 82/220R as a power source. 2 An external 100 g ASTM Class 0 reference calibration weight (/-) was used to calibrate the analytical balance. I put the weights of the items in this set to the test (130 ug). They filled out the following forms: br>br>10 gram - 20g 00159 gbr>00159 gbr>00159 gbr>00159 gbr>00159 g gbr>20g 99577 gbr>99577 gbr>99577 gbr>99577 99664 g (top pin was slightly tilted in the box due to being loose)br>50 g - 100g - 99365g - 99365g - 99365g - 99365g - 99365g - 99365 100 100 g - 0078 gbr>0078 gbr>0078 gbr>0078 gbr 100 200g - 0080 gbr>0080 gbr>0080 gbr>0080 gbr> 500g - 0068 gbr>0068 gbr>0068 gbr>0068 gbr> 500 00 g (This item was outside the scale's measurement range and was compared to a 500g ASTM Class 1 reference weight on a calibrated centigram scale, which was accurate to decimal places. ) br>br>As a result, this is primarily an ASTM Class 6 set, with some weights deviating enough to fall into ASTM Class 7 (IOLM Class M2). To put it another way, this is about as inaccurate a calibration set as you can get, at least in terms of ASTM calibration classes (7 being the worst). However, for the money, it's a good set for low precision (i. e. Scale calibration of scales that go down to centigrams (every day/mere mortal).
Two of the small ones had fallen out of their spots in the box when they arrived, but we were unharmed. Also, the included plastic tweezers are too flexible to pick up anything heavier than the 200g weights, so you'll want to invest in some stiffer tweezers or a nice glove to handle them with. br>I used my calibrated scale to measure them all and discovered that they were all within a few tenths of a milligram of each other, with the 500 being the worst at 0. Under the weight of 0007g Not bad for the money!br>I've taken pictures of my measurements.
The 500g weight was two tenths off, rendering the set useless. Only two of the weights in the set were accurate, while the rest were all off. The ball top was said to have come off in other comments. The weight will be completely ruined if the ball top comes off! Some reviews mention "amazing tongs," but they're nothing more than thin plastic garbage. I don't usually write reviews, but I felt compelled to do so for this dreck.
If you're missing a pound, it's because you're missing This is how it arrived, all broken up, with a 20g weight missing. They weren't in the case at the time, so I just stuffed them in. They were freely clanking around in the package, and as you can see, the package is torn where the 20g weight escaped, so aside from the fact that it was packaged carelessly and it's missing a weight and I have no case, it arrived in a timely manner and the weights are exactly what I expected.
This set of masses, as well as a smaller set of masses (0. To calibrate an old Mettler P1210 scale (0. 1g to 100g). Precision of 0. 1 gram). The Mettler has a large internal reference mass for multiples of 100g due to the way it is constructed. In addition, I had a large number of 10, 20, 50, and 100 gram masses between the two sets, which I could combine to make 100 gram units to compare to the internal reference masses. In a nutshell, everything is measured within the scale's accuracy. Any combination of masses was measured as expected and within the scale's accuracy (0. 0. 01 gram). br>br>While weighing the set on a known scale would be ideal, I found these masses to be very accurate within the limits of my testing.
Because of the shipping, I was docked two stars. This item is fantastic. The weights are accurate, made of high-quality metal, and the storage case and tweezers are extremely useful. Because of how Amazon delivered it to me, I'm only giving it three stars. Only a bubble envelope was used to ship the box of weights, and the plastic case was severely chipped and broken when it arrived. It's not bad enough for me to send it back, but I was hoping Amazon would ship it in a more secure box. The weights are heavy, and the bubble envelope wasn't strong enough to keep them safe.
My scale needed to be calibrated if they were truly "M2. " (The weight of a 500gm "M2" should be within /- The scale was off by 0. 08 gm, indicating that the weight was incorrect. 35 gm). Because of the variation in gravity, g=9, I'm not so sure. In London, it's 816, but in Los Angeles, where I live, it's g=9. That is a zero. 002% variation or a 1 gm difference in weight weight weight weight weight weight weight weight weight weight weight weight Unless I know where or how the scale was calibrated, its original calibration is in doubt! If these weights are truly "M2" mass toleranced, I can ignore all of that when calibrating my scale, resulting in a properly "mass" calibrated scale.
Only buy this if the accuracy of your kitchen scale is a major concern for you. Using these weights, I discovered that my digital kitchen scale was reading more than two pounds higher than it should have been. 4%. (This is irrelevant to the majority of recipes. ) ) Since this is my first check in over a decade, it seems like a lot to pay for something that is only used once in a while. But, for the sake of peace, I would buy these again. mind. What I don't like: The cheap, flimsy tweezers do the job, but U-shaped tweezers would be a better option. a hook with a perpendicular to the handle shape; could be made of the same material, but it would be a safe way to get the weights from their case to the scale. back.
