Abstract

An electronic balance with a digital display for the exact display of the weighing result, with an quasi analog display for the estimated display of the balance (gross) load, whereby the a quasi analog display consists of at least one horizontal band of activatable points (7), and with a taring operation, that suitable activatable segments (8, 10) be located within, directly above or directly below the first horizontal band of activatable points (7) with which such suitable segments a "T" symbol (9) can be activated at a plurality of positions along the first horizontal band and that the "T: symbol be activated during taring at the horizontal position which corresponds to said tare weight on the horizontal band (7) of the quasi analog display while a horizontal bar formed by suitable activation of activatable points indicates gross weight. This makes it possible to display in a simple manner the relative position at which taring was performed. Still other segments (8, 10') can also be used in an advantageous manner as a scale for the quasi analog display.
