5. Configuración

5.1 Desembalaxe e inspección 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 Colocación

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 Nivelación do equilibrio

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).

Figura 5.1: Horizontal Adjustment. Adjust leveling feet until the bubble is centered. Proper leveling is essential for accuracy.

5.4 Conexión de alimentación

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 Warm-up Time

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. Instrucións de funcionamento

6.1 Encendido/apagado

  • Preme o ON/OFF button to turn the balance on.
  • Manteña premido o ON/OFF button to turn the balance off.

6.2 Pesaxe básica

To perform a basic weight measurement:

  1. Ensure the balance is level and has completed its warm-up.
  2. Preme o TARA / CERO botón para axustar a pantalla a 0.000 g.
  3. Carefully place the item to be weighed on the center of the weighing pan.
  4. Agarde a que a lectura se estabilice. Mostrarase o peso estable.

6.3 Función de tara

The tare function allows you to subtract the weight of a container, so only the net weight of the contents is measured.

  1. Coloque un recipiente baleiro na tixola.
  2. Preme o TARA / CERO 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 Conversión de unidades

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

  • Preme o UNIDADE 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 % (percentage).
  • A unidade seleccionada mostrarase na 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. Preme o PCS botón.
  3. Select the corresponding sample quantity using the UNIDADE botón.
  4. Preme 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 Porcenttage Pesaxe

O porcenttage function is useful for formulation and quality control, allowing you to measure a sample's weight as a percentage dun peso de referencia.

  1. Coloca a referencia sample na balanza.
  2. Preme o UNIDADE button until '%' is displayed. The reference weight will be set as 100%.
  3. Elimina a referencia sample.
  4. Place subsequent samples on the pan. Their weight will be displayed as a percentage do peso de referencia.

6.7 Calibración

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.

  1. Ensure the weighing pan is empty and the balance is stable.
  2. Manteña premido o CAL button until 'CAL' appears on the display.
  3. The display will then show the required calibration weight (e.g., 500.000g).
  4. Carefully place the specified calibration weight (provided) onto the center of the weighing pan.
  5. Wait for the balance to automatically calibrate. Once complete, the display will show 'PASS' or return to normal weighing mode.
  6. Remove the calibration weight.
