Make sure it is clean (if your sample will come in contact with it) and functioning properly.
Other than that, it depends very much on what type of equipment you are specifically referring too. Some instruments need to warm up before use, glassware should be cleaned and dried, and you may want to weigh certain flasks and beakers if you will need to later know the mass of what is inside.
Alchemy was the first.
The one that discovered Chemistry is Democritus.
To do 10th chemistry practicals, first carefully read and understand the given experiment. Then gather all the required chemicals, apparatus, and safety equipment. Follow the step-by-step instructions provided in the experiment, making sure to record observations and results accurately. Finally, clean and store the apparatus properly after completing the experiment.

Length comes first in measure quadrilaterals.
Any test equipment that your life may depend on when using it must first be tested before being used. These types of test equipment usually have internal apparatus that can verify that the equipment is working perfectly before it is used by personnel. Linesmen use this type of test equipment before working on primary voltage lines.
You should check first your measuring devices before you use it for a true and accurate measures.
You must read first the instructions in the manual before operating the new equipment to avoid errors.

the answer to this question is who do you think made the first measuring cup?
Laboratory research in applied chemistry is the first step to industrial chemistry.
Artificial intelligence is a computer programming objective; it is not directly related to chemistry. It does require knowledge of chemistry in order to be able to build computers in the first place, but the computers are already built before you begin to study artificial intelligence.
We can consider that chemistry begin with the apparition of the first Homo sapiens.
Fahrenheit created the first thermometer for measuring temperature. Before he created his thermometer, people did not have a precise way to describe temperature.
