Instrucións de funcionamento
Pesaxe Básica
- Turn on the scale. Wait for the display to show "0.00".
- Place the item(s) to be weighed on the center of the weighing pan.
- Read the weight displayed on the "WEIGHT" LCD screen.
- To change units (g/kg/lb), press the UNIDADE botón.
Función Tara
The tare function allows you to subtract the weight of a container, so only the net weight of the contents is measured.
- Coloque un recipiente baleiro na tixola.
- Preme o TAREAR button. The display will reset to "0.00", indicating the container's weight has been tared.
- Add items to the container. The display will show the net weight of the items.
- To clear the tare, remove the container and press TAREAR de novo.
Función de conteo
This scale can count items based on a sample unit weight.
- Asegúrese de que a escala estea en cero.
- Place a known quantity of sample items (e.g., 10, 20, 50, 100 pieces) on the weighing pan.
- Introduza o sample quantity using the numeric keypad (e.g., "10" for 10 pieces).
- Preme o SMPL (Sample) button. The scale will calculate and store the unit weight, and the "TOTAL COUNT(PCS)" display will show the sampa cantidade.
- Elimina o sample items. The "TOTAL COUNT(PCS)" display should return to zero.
- Place the items to be counted on the weighing pan. The "TOTAL COUNT(PCS)" display will show the total number of items.
Calibración manual
Regular calibration ensures the accuracy of your scale. This scale features an easy manual calibration mode.
- Refer to the specific calibration procedure outlined in the full product manual or contact customer support for detailed steps. Typically, this involves entering a calibration mode, placing a known calibration weight, and confirming the reading.
- Ensure you use certified calibration weights for the best accuracy.
