A set of kitchen scales marked to weigh in grammes.
By calibrating the instrument using a known measure.It can also be eliminated by adding measurements - or taking a measurement from a point other than 0.For example, suppose you have scales with a zero error: say of 5 grams. And you want to 100 grams of flour. If you just put flour in the scale's tray, you will get 95 grams when the scale reads 100 g. However, if you put a bowl there, take a reading m1 grams and then add flour until the reading is (m1 + 100) grams then you will have 100 grams of flour.
