Mass balance reset to zero. This mass balance has been reset to zero after the glass beaker was placed on it. This makes it easier to measure the mass of a liquid or other chemical added to the beaker. The beaker's weight is called the tare weight, or unladen weight. The reset-to-zero button is at lower right (yellow).
