Balance with counting scale
First Claim
1. Balance with counting scale with a tare key (7) for setting the display to zero and with a transfer key (8) which can bring about the transfer of the weight of a certain number of pieces into a memory (16) of the built-in electronic circuitry for determination of the average individual weight, characterized in that a comparator (14) is present in the built-in electronic circuitry which is actuated when the transfer key (8) is pressed and which frees the transfer of the weight into the memory (16) and the determination of the average individual weight when a set threshold is exceeded, while, when this threshold is dropped below, it does not free the transfer of the weight into the memory and increases the resolution of the balance by a given factor.

Abstract
The invention indicates a balance with counting scale in which the resolution of the balance with counting scale can be increased in the determination of the reference weight of light pieces without an additional switching key operated from the outside. To this end, a comparator (14) is present in the built-in electronic circuitry which is actuated when the transfer key (8) is pressed and which frees the transfer of the weight into the memory (16) and the determination of the average individual weight when a set threshold is exceeded, while, when this threshold is dropped below, it does not free the transfer of the weight into the memory and increases the resolution of the balance by a given factor.
