Scale Operations
The SPS-300 Series can be interfaced to an optional load-cell scale. The scale interface allows direct
entry of an item's weight using the SCALE function. You can also choose "manual entry" scale
operation if you are working with a standalone scale that is not interfaced to the cash register.
• PLUs must be set to "scalable" status to allow scale multiplication. If you attempt an entry
into a PLU that has been programmed "scalable", an error tone will sound and the operator
will be prompted to make a scale entry.
• PLUs can be set to "auto scale" status to speed up scale entries by automatically retrieving
the weight on the scale and multiplying the amount entered.
A tare is the amount of weight accounted for by the container or packaging. By entering a tare weight
(as required by law in some areas) the weight of the container is subtracted and only 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 product is on the scale.
• PLUs can be set to "auto tare" status to automatically subtract one of the pre-programmed
tare weights when the PLU is registered.
Refer to the Manual to set your scale options. See:
• Service Mode Programming, Function Key Assignment to program SCALE and TARE
keys on the keyboard.
• Service Mode Programming, RS232C Port 1,2,3 or 4 Options to program a scale to one of
the ports.
• Program Mode Programming, Function Key Programming to set options for the SCALE
and TARE keys.
• Program Mode Programming, PLU Programming to set scalable, auto scale, or auto
tare status on the PLUs.
NOTE: Decimal point key is only used for weight (kg) entry, never for dollar amount.
