5. Configuració

5.1 Desembalatge i inspecció inicial

Carefully remove the balance from its packaging. Inspect all components for any signs of damage. If any damage is found, do not use the balance and contact customer support immediately.

5.2 Col·locació

Place the balance on a firm, level, and stable surface. Ensure the location is free from vibrations, drafts, direct sunlight, and rapid temperature fluctuations, which can affect measurement accuracy.

5.3 Leveling the Balance

The balance must be perfectly level for accurate readings. Use the adjustable feet at the bottom of the balance to center the bubble in the integrated level indicator (refer to Figure 4.4).

5.4 Connexió d'alimentació

Connect the provided power cord to the balance and a suitable power outlet (100-240V). Alternatively, the balance can be powered by a 9V battery for portable use.

5.5 Temps d'escalfament

After connecting power, allow the balance to warm up for at least 30 minutes before taking measurements. This stabilizes the internal components and ensures optimal accuracy.

6. Instruccions de funcionament

6.1 Encès/Apagat

  • Premeu el botó ON/OFF button to turn the balance on.
  • Manteniu premut el botó ON/OFF button to turn the balance off.

6.2 Pesatge bàsic

To perform a basic weight measurement:

  1. Ensure the balance is level and has completed its warm-up.
  2. Premeu el botó TARA / ZERO button to set the display to 0.000g.
  3. Carefully place the item to be weighed on the center of the weighing pan.
  4. Wait for the reading to stabilize. The stable weight will be displayed.

6.3 Funció de tara

La funció de tara permet restar el pes d'un recipient, de manera que només es mesura el pes net del contingut.

  1. Col·loqueu un recipient buit al plat de pesatge.
  2. Premeu el botó TARA / ZERO button. The display will reset to 0.000g.
  3. Add the material to be weighed into the container. The display will show the net weight of the material.

6.4 Conversió d'unitats

The balance supports multiple weighing units. To change the unit:

  • Premeu el botó UNITAT button repeatedly to cycle through available units: g (grams), ct (carats), oz (ounces), ozt (troy ounces), lb (pounds), gn (grains), t (metric tons), dwt (pennyweights), kg (kilograms), dr (drams), tlT (Taiwan Tael), N (Newtons), and % (percentagi).
  • La unitat seleccionada es mostrarà a la pantalla.

6.5 Parts Counting (PCS)

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

  1. Place a known quantity of items (e.g., 10, 20, 50, 100, 150, 200, 250, 500) on the pan.
  2. Premeu el botó PCS botó.
  3. Select the corresponding sample quantity using the UNITAT botó.
  4. Premeu PCS again to confirm. The balance is now in counting mode.
  5. Add more items, and the display will show the total count.

6.6 per centtage Pesatge

El percentatgetage function is useful for formulation and quality control, allowing you to measure a sample's weight as a percentage d'un pes de referència.

  1. Col·loca la referència sample a la safata.
  2. Premeu el botó UNITAT button until '%' is displayed. The reference weight will be set as 100%.
  3. Elimina la referència sample.
  4. Place subsequent samples on the pan. Their weight will be displayed as a percentage del pes de referència.

6.7 Calibració

Regular calibration ensures the accuracy of your balance. It is recommended to calibrate the balance upon initial setup, after relocation, or if you suspect inaccurate readings.
