List four things to avoid doing when using the balance.

Some of the things to avoid when using the balance are as follows:

1. Do not open the balance casing unless the chemical to be weighed will be put in. This is to avoid excessive moisture from entering the system.

2. Wait for the weight reading to stabilize before clicking the "tare" button.

3. Do not carry the balance when a sample is inside.

4. Do not weigh samples beyond the recommended capacity of the balance.
