5. Operating Instructions
5.1 Basic Weighing and Price Computing
- Turn on the scale using the power switch. Allow it to stabilize and display "0.00" in the Weight window.
- Place the item to be weighed on the center of the stainless steel platter. The Weight display will show the item's weight.
- Using the numeric keypad, enter the unit price (e.g., for $1.50/lb, enter "150"). The Unit Price display will show the entered value.
- The Total Price display will automatically calculate and show the total cost (Weight x Unit Price).
- Remove the item from the platter. The display should return to "0.00".
5.2 Tare Function
The Tare function allows you to subtract the weight of a container, so only the net weight of the product is measured.
- Place the empty container on the weighing platter. The Weight display will show the container's weight.
- Press the TARE key. The Weight display will reset to "0.00", and the tare indicator will illuminate.
- Place the product into the container. The Weight display will now show only the net weight of the product.
- To clear the tare, remove the container and product, then press the TARE key again, or turn the scale off and on.
5.3 Zero Function
The Zero function is used to reset the scale to zero when there is a small amount of residual weight on the platter or if the display drifts slightly.
- Ensure the platter is empty.
- If the display shows a small non-zero value, press the ZERO key. The display will reset to "0.00".
5.4 Price Look-Up (PLU) Function
The scale supports up to 999 Price Look-Up (PLU) codes for frequently sold items, allowing for quick recall of unit prices.
5.4.1 Storing a PLU
