Explanation:
Detailed explanation-1: -Weighing directly requires that the balance be carefully zeroed (reads zero with nothing on the balance pan) in order to obtain accurate results. A clean piece of weighing paper is placed on the balance and weighed.
Detailed explanation-2: -The pan balance is a useful tool to check the relative weights of any two cubes.
Detailed explanation-3: -The Zero function should only be used when there is nothing on the scale, but the reading doesn’t display Zero. This is a permanent recalibration of your scale to remove unwanted weight from dust, rust or other build up.
Detailed explanation-4: -Types of balance Top-pan balance (200g – 0.001g) Analytical balance (320g – 0.0001g) Microbalance (6g – 0.000001g)
