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) while 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. |
