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.
