5. Configuració

5.1 Installing the Weighing Pan

1. Carefully remove the balance and all components from the packaging.
2. Place the weighing pan support onto the central pillar of the balance. Ensure it is seated correctly and securely.
3. Place the stainless steel weighing pan on top of the pan support.

5.3 Connexió d'alimentació

The balance can be powered by either an AC adapter or a 9V DC battery:

• Alimentació CA: Connect the provided AC adapter to the power input port on the back of the balance and then plug it into a standard 100-240V AC outlet.
• Potència de la bateria: For portable use, open the battery compartment on the underside of the balance and insert a 9V DC battery.

5.4 Temps d'escalfament

For optimal accuracy, allow the balance to warm up for at least 30 minutes after connecting power or if it has been off for an extended period. This stabilizes the internal components for precise measurements.

6. Instruccions de funcionament

6.1 Pesatge bàsic

1. Premeu el botó ON/OFF button to turn on the balance.
2. Ensure the display shows "0.00g" before placing any item on the pan. If not, press the TARA / ZERO botó.
3. Place the item to be weighed gently on the center of the weighing pan.
4. Read the stable weight displayed on the LCD.

6.2 Selecció d'unitats

4. Place each weight carefully and wait for the balance to stabilize before proceeding to the next step or removing the weight as instructed.
5. Once all points are calibrated, the balance will return to normal weighing mode.

6.5 Piece Counting Function

This function allows you to count a large number of identical items by weight.

1. Col·loca comample quantity of items (e.g., 10, 20, 50, 100, 200, or 500 pieces) on the pan.
2. Manteniu premut el botó PCS button until the display shows "PCS" and a number (e.g., "10 PCS").
