An example of a special laboratory tool is an analytical balance, which is used by scientists in laboratories to measure the weights of various objects to a high degree of precision.
At, you have to ensure that your scales are correct; the also applies to the analytical balances scientists use and must check often. To calibrate means to ensure that we have set the balance up
In lab, scientists weigh various things such as powders, liquids, or tiny crystals on an analytical balance. This allows them to do accurate calculations and mix the appropriate quantities of each
Analytical balances have sensors within that detect how much force an object is pushing down on the platform when you place an object onto it. This force is then converted to a weight that is displayed
The analytical balance should be handled according to some simple rules. First, ensure the balance is on a stable surface, as one might find on a table, and is far away from anything that shakes (or moves)
