Before weighing anything on the analytical balance you must make sure that it is leveled and zeroed.
To check the leveling on the balance, look at the leveling bubble on the floor of the weighing chamber. If it is not centered, center it by turning the leveling screws on the bottom toward the back of the balance.
Once the balance is leveled, close all the chamber doors and press the control bar on the front of the balance. After a few seconds, a row of zeros will appear. This indicates that the balance is zeroed and ready for use.
These substances must always be weighed using an appropriate weighing container.
If the object you need to weigh is a solid object, you can weigh it directly on the pan. Be sure the balance is zeroed. Open the chamber doors, carefully place the object on the balance pan, close the doors, and read the mass of your object.
When you are done with the balance, make sure you have properly cleaned
up any chemicals that may have spilled on the balance. At the end of the
day, the balance can be turned off by lifting up gently on the control bar.
