Abstract
A single load cell 10 both (A) measures the load on a elevator hitch providing an analog elevator load signal on line 11 to an analog-to-digital converter 20 via line 18, for providing a digital elevator load signal and (B) is used for providing a dynamic tare of elevator load weighing system for calibrating the analog-to-digital converter 20 by adjusting an analog reference voltage (V.sub.ref) until the digital elevator load signal is equal to the dynamic tare.
