SAM4s SPS-300 Series Operators Manual.pdf

Scale OperationsThe SPS-300 can be interfaced to an optional load-cell scale. The scale interface allowsdirect entry of an item's weight using the SCALE function. You can also choose "manualentry" scale operation if you are working with a standalone scale that is not interfaced to thecash register.PLUs must be set to "scaleable" status to allow scale multiplication. If youattempt an entry into a PLU that has been programmed "scaleable", an error tonewill sound and the message “REQ. SCALE ENTRY” will display.PLUs can be set to "auto scale" status to speed up scale entries by automaticallyretrieving the weight on the scale and multiplying it times the amount entered.A tare is the amount of weight accounted for by the container or packaging. By entering atare weight (as required by law in some areas) the weight of the container is subtracted andonly the true weight of the product is measured on the scale. By entering the tare number (1-5) the operator can automatically subtract the predetermined container weight when a productis on the scale.PLUs can be set to "auto tare" status to automatically subtract one of thepreprogrammed tare weights when the PLU is registered.Refer to the "Service Mode Programming" and "Program Mode Programming" chapters to setyour scale options. See:"Function Key Assignment" to place SCALE and TARE keys on the keyboard."RS232C Port Options" to attach a scale to one of the ports."Function Key Programming" to set options for the SCALE and TARE keys."PLU Programming" to set scaleable, auto scale, or auto tare status.84 • Operations SAM4s SPS-300 Operator's & Programming Manual v1.2
