Regularly calibrate all measuring instruments before conducting experiments.

Answer 1

The phrase "Regularly calibrate all measuring instruments before conducting experiments" means that you should consistently check and adjust the accuracy of the tools and devices used to take measurements (like scales, thermometers, or sensors) to ensure they provide correct and reliable data. Calibration is the process of comparing the instrument's measurements to a known standard and making necessary adjustments. By doing this regularly before any experimentation, you help ensure that the results you obtain are valid and accurate.
