Zero the balance: Push the “tare” or “zero” button to reset the balance to zero while in the no-load condition. This compensates for the weight of any containers or vessels applied through the calibration system.
Performance Test: Put ten various exam weights inside the potential check here assortment in the course of the pan. Every measurement really should be within the mistake range.
