A. Yes. Before taking the pH measurement of your solution, you must calibrate the pH meter. Particularly if it has been stored or used to test a pH range that vastly differs from the one you currently need to test. When you calibrate a meter, you are simply checking and fixing the pH meter and probe ensuring that is reads pH correctly.
