There are some tips on how to adjust or regulate the dissecting microscope. First of all, the user must ensure to start with the microscope on the lowest magnification power just like to start with 7x instead of 10x. The user must put the specimen on stage. Then the light of the microscope must be switched on. The light is generally situated underneath the stage of the microscope. If the light is not located under the stage, then the microscope must be utilizing an external light source. In such case, the user must position the light at the specimen though maintain the light as distant from the specimen as possible to prevent it from overheating the specimen. Regulate the eyepiece so that they have the correct gap apart for the user to view through them. Such is being performed by gently drawing them apart or thrusting them together. Instruct the students to view through the eyepiece to look if the student is able to observe the specimen at all.

Try to move the eyepiece a little bit to obtain a better view. Also ensure to regulate the level of light going to the specimen. It is best to utilize as modest light as it possibly can to provide better contrast of the specimen that will make it simpler to view. In case the light is extremely bright or overly dark then the student might not be able to view the specimen extremely well. Gradually modify the coarse adjustment while watching at the specimen through the eyepiece. The student or the operator must perform this starting at the upper portion of the microscope known as the objective as near to the specimen as possible without touching it. Utilize the coarse adjustment knob to turn the objective distant from the specimen until it comes into proper focus. As the student of the operator gradually moves the adjustment knob, he or she will notice the image will become clearer and clearer. Stop regulating when the specimen is at its most clear picture. When the specimen has been fully focused with the coarse adjustment the microscope can be moved up to a higher magnification power by adjusting the magnification control knob. The operator must ensure to only adjust the knob up by one magnification at a time and then stop to view through the eyepiece.

There are also guidelines or policies to make use of when utilizing a microscope. First, students must be instructed to be cautious and gentle each time they operate a dissecting microscope or any other kinds of microscope. The microscopes are sensitive and costly. If every kind of material from the specimen like water gets into any portion of the microscope, make sure that it will be wiped off instantly and cautiously. When transferring or transporting the microscope, grasp it beneath the stage at all times and hold the arm firmly with another hand. Do not bring the microscope by its cord or without any support to the stage area. At all times regulate the coarse adjustment with the microscope on the lowest energy. In such manner it will make it simpler to focus on the specimen and not destroy any parts of the microscope.
