Question: is it a must to calibrate with the calibration weight? or can something else calibrate it? my nickle scale at 37.6!and just got the scale today too-_-
Document: I got this electronic scale for weighing out my gold jewelry in preparation for selling it. It does need to be calibrated, but the calibration weights that Amazon recommends for it are not the right ones. You only need one calibration weight, and it really needs to be 500 gm. Nothing else will do.It can weigh your items in grams, ounces, Troy weight, and penny weight. Unfortunately, it does not have the option to weigh your items in carats.
Just got it in today. Bought it along with the 500 g weight. The scale was off by around 1.5 grams (I say that because I am trusting the weight.) After calibration, it seemed like it has .1 g tolerance, depending on where you place the scale (corners tend to read 499.9-500.1 ) but pretty consistent in the center. Comes with batteries loaded in, just remove the plastic protector and weigh.
Not the best when it comes to measuring 0.1g increments but that's not what I got it for (for that I have a centigram scale by the same brand).I'm really impressed at how this scale is holding up, I tried to calibrate it for the first time after 7 months of abuse (I use it to measure my diy-soylent, it always gets covered in powders water and oil) but it was still perfectly accurate (showing 100.0 with a 100g calibration weight.)
Is is so compact and the 10-year warranty it has make it best buy under this category. Its usage depends on person to person, if your requirement to weigh small items all the time than it is the best, else you should have something bigger which can weight more than 1000g.
Great little scale. Works well and do not cost very much at all. When you buy it however, you must buy a calibration weight so the weight is accurate every time. This will cost an additional $3. Very handy for many reasons.
I bought this scale for my girlfriend, so she could use to weight some jewelry. I must say that for the price, this is a great deal! And my girlfriend loves it! I also bought a 500g calibration weight just to check the scale, and it seems to be working fine. I guess this is a must have for any women that likes jewelry. I highly recommend it!
The scale doesn't let you select your calibration weight, so you must use the 500g one.The scale has a nice tare feature. You put your dish on the scale, then press tare. This resets the scale to show 0 grams. Then, whatever you add to the plate will be measured because the scale has already done the subtraction for the weight of the dish.As for precision, sometimes the 500g weight shows up at 500.1 grams or the 50g weight will show up as 49.9.
I have used this little scale quite a bit. It is very easy to calibrate (500 gram calibration weight required), and holds its calibration and accuracy without any issues. Very convenient and easy to use.
My son is diabetic and all his food must be weighed. This little scale is perfect for keeping in his supply pack and taking with us to visit friends, to restaurants, etc. I weighed a nickle with it when it arrived - 5 grams just the way it should be. It even weighs in tenth of grams so I know if I want to round up or down on the carb counts.
this is a very nice and easy to use scale. Easy to use to weigh anything. I bought it just to play with my coins and to see their weight. Seems to be very accurate. I purchased a set of calibration weights so I had something to zero my scale with.
Answer: you need to calibrate with something if you want to have a scale that measures properly; 1 of the 3 scales i've bought similar to this weighed accurately from the factory; one was 1.5% off the other was 3-4% off. I was able to calibrate one of my scales using 100ml and 200ml of water; however i was able to use a scale I knew was accurate to measure that water (since it really was maybe 95ml water and 5g of plastic cup). the nickel =5g does work pretty well but it would take 100 to get 500g; i've seen a batch of nickels off quite a lot but on average in my tests they come out very close to 5.0g (example 7 nickels should be 35g and was 33.5g but by the time I got to 10 it was 49.8g or 50.1g for example). You can get a few rolls of nickels or you can just buy a 500g weight for about the same price.
