Step 4 — Programme the Scale

Using the scale's front panel or USB programming tool (refer to your scale's own manual), enter a PLU entry for each item. The PLU number must be the same as what you entered in Step 3 on the item record.

Daily Use

Once setup is complete, the cashier's process is simply:

Customer places a weighed item on the counter.
Cashier scans the barcode label.
The item appears in the cart with the weight and price filled in.
Proceed to payment as normal.

What the Barcode Contains

If you are curious, here is what the scale encodes inside its 13-digit barcode:


Part of the Barcode	What It Holds
First digit	Scale prefix (e.g. 2) — tells PH POS this is a scale barcode
Next 5 digits	PLU number — identifies which item this is
Next 5 digits	Weight in grams or total price — depending on Scale Rule mode
Last digit	A check digit — PH POS uses this to confirm the barcode was read correctly
