    • A cash till having a drawer (2) with a plurality of compartments (4) for storing coins, notes or vouchers. Each compartment (4) has an associated load cell (6), which produces a signal that is proportional to the weight of the compartment contents. The signal is provided to a monitoring apparatus (10) that takes readings from the load cell (6) whilst the till drawer (2) is closed. If a preceding reading is within a threshold amount of the current reading, then the preceding reading is stored as a verified value. The method removes jitter and drift in the signals produced by the load cells (6) of the cash till.
    • 一个现金直到有一个抽屉(2)与多个隔间(4)存储硬币,票据或凭单。 每个隔室(4)具有相关联的称重传感器(6),其产生与隔室内容物的重量成比例的信号。 该信号被提供给监视装置(10),在监视装置(10)在直到抽屉(2)关闭的同时从称重传感器(6)读取数据。 如果前面的读数在当前读数的阈值内,则前一读数被存储为验证值。 该方法消除由现金的称重传感器(6)产生的信号中的抖动和漂移。
