I use digital scales for weighing ingredients - which is fine for medium and large quantities like flour, sugar, butter etc. for baking. But when it comes to weighing smaller quantities, they aren't accurate. I place a tiny dish on the scales and zero them. Then add, for example, salt. Most bread I make requires 9g of salt to 500g of flour. But I find I can add quite a lot more salt or take some out when the scales read 9g and the weight reads the same. It also changes according to where on the scales I place the dish. What do other people do? I'm sure there must be scales specially designed for small amounts. Does anyone have a recommendation?
