I bought some digital cooking scales last weekend and discovered something weird. I put a little bowl on them, zeroed the scales, and then started pouring salt into the bowl until they read 10g (the scales are meant to have a resolution of 1g). I thought the quantity looked a bit much, so I took the bowl off the scales and put it back on, and the scales read 14g. I poured the salt out of the bowl and put the bowl back on the scales, and they read 0g. I dumped the salt back into the bowl all in one go and the scales read 14g again! I tried the whole procedure several times and got the same result. What's going on here?
I tested the scales against some deli containers I'd bought which had the weights marked on the price tag and they seemed quite accurate. So what's the best way to use these scales so that I get the most accurate results? Should I limit myself to putting larger quantites of stuff in them at a time rather than pouring things in slowly?
