Abstract

To start a metering process, the operator enters the desired weight value into a display control. The display contains a container shaped figure which is "filled" as material is added to the balance. The rate at which the container fills relative to the rate at which the substance is being applied to the instrument changes during the metering process. It is slow during the coarse starting phase and more rapid during the final fine metering phase. The shape of the bottle preferably corresponds to the "fill" rate, i.e. it is relatively wide at the bottom and has a narrow neck at the top. The display is controlled by a microcomputer.
