Use these calibration weights alone, or combine them to accurately calibrate your digital weighing scale.
Q: Does the weight set come with certificate of calibration?
A: Hey there Robert,No this weight set does not come with a certificate of calibration.
Q: Just want to check about tolerances: If I am combining weights for example to get 150 g and have the 100g +/- 15mg and the 50g +/- 10 mg my total error would be +/- |15+10| or +/- 25mg, right? or if I add up to 180g with the 100g, 50g, 20g, & 10g, the total error possible would be +/- |15 + 10 + 8 + 6| or +/- 39mg. Thanks.
A: Hey there mb,Yes that is correct. You have to take into account the tolerances of the weights themselves, and the tolerances of the scale being used. That doesn't mean the added weight value WILL be off by that much, but it helps to know just how far off the weight value COULD be.Take care,Brandon
