<p>Digital price determination scales have force/frequency transducer, calculator, multiplier, indicator, register, price input, control unit and tare compensation device. The transducer is connected to the calculator which supplies the indicator and register. The control inputs of the calculator are connected to the control unit which is switched to the control input of indicator and register. The tare compensation device (22) removes the tare from the calculation of the price. It sets the scales to zero and comprises a tare counter. The counter input (26) is in connection with the frequency output (3) of the force/frequency transducer (2) via AND gates (23).</p> |
