Abstract

A balance is provided with a digital readout, a display device and transfer device for transferring measured values to the display device at a selected frequency. The frequency can be varied. An accessory circuit is provided for modifying at least the last digit appearing on the display device in response to an arrest criterion or a condition of the balance, such as an open measuring chamber or position of a draft shield. The criterion can be developed from comparing successive measured values.
