5.2 Conversió d'unitats

To change the weighing unit (g, mg, ct, oz), press the UNITAT repetidament fins que es mostri la unitat desitjada.

5.3 Piece Counting Function

  1. Zero the balance.
  2. Premeu el botó ON button several times continuously until "COU" is displayed.
  3. Premeu O / T per entrar i utilitzar ON to select the desired quantity (e.g., 5, 10, 20, 50, 100, 200 pieces).
  4. Place the corresponding quantity of samples on the pan and press O / T to confirm. The balance will now be in counting mode.
  5. Col·loca el sample to be counted on the pan and read the value.
  6. Premeu ON i O / T to return to the weighing page.

5.4 per centtage Weighing Function

  1. Zero the balance.
  2. Premeu el botó ON button several times continuously until "PCT" is displayed.
  3. Premeu O / T per entrar.
  4. Col·loca la referència sample on the pan after "PCT 100PCT" is displayed and confirm by pressing O / T.
  5. Posa el sample to be weighed on the pan after "100.00 PCT" is displayed and read the percentage valor.

6. Calibració

Regular calibration ensures the accuracy of your analytical balance. The USS-DBS48 supports both internal and external calibration.

6.1 Internal Calibration

  1. Ensure the balance is stable and zeroed.
  2. Premeu el botó CAL button. The display will show "CAL-INT".
  3. The balance will automatically perform internal calibration. Wait until the process is complete and the balance returns to weighing mode.
