An electronic balance includes circuit means for providing a plurality of electrical pulses representing the weight of an object positioned on the balance. Storage and comparator means are provided to selectively store tare weight representative signals and to control the application of the electrical pulses to a display circuit such that only the pulses corresponding to a weight exceeding the stored tare weight are applied to the display. The system, therefore, can automatically compensate for an unknown tare weight of a sample holder by storing the weight of the sample holder and provide a read-out of only the weight of the sample then positioned in the sample holder.
