7. SENSITIVITY CALIBRATION

The electronic balance measures mass by electronicity compensating for terrestrial

gravitation. Since gravitation varies slightly in different regions, span calibration (sensitivity

calibration) is required when the balance is installed. Temperature also effects balance

accuracy, and calibration must be performed whenever a significant change occurs. It is

good practice to calibrate the balance whenever the balance is moved or unexpected shock

is applied to the balance such that an article drops on the pan.
