7.3 Funzjoni tat-tara
Il-funzjoni Tare tippermettilek tnaqqas il-piż ta' kontenitur, biex b'hekk jitkejjel biss il-piż nett tal-kontenut.
- Place an empty container onto the weighing pan. The display will show its weight.
- Agħfas il- TARE buttuna. Id-displej jerġa' lura għal "0.00" (jew "0.000").
- Add the items to be weighed into the container. The display will show the weight of the items only.
7.4 Konverżjoni tal-Unità
The scale supports multiple units of measurement.

Agħfas il- MODALITÀ Agħfas il-buttuna ripetutament biex tgħaddi mill-unitajiet disponibbli:
- Lira (lb)
- Uqija (oz)
- Kilogramma (kg)
- gramma (g)
- Karat (ct)
- Tael (tl)
- Piece Counting (pcs)
7.5 Piece Counting (PCS)
This function allows you to count a large number of small, uniform items.
- With the scale on and showing "0.00", place a sample quantity of items (e.g., 10, 20, 50, or 100 pieces) on the weighing pan.
- Agħfas u żomm il- PCS Agħfas il-buttuna sakemm jidher "PCS" fuq id-displej.

- Agħfas u żomm il- MODALITÀ buttuna, imbagħad agħfas il- ON/OFF Agħfas il-buttuna simultanjament. Itlaq iż-żewġ buttuni meta jidher "CAL" fuq id-displej.
- The display will show a flashing weight value (e.g., "200.00g" or "500.00g"), indicating the required calibration weight.
- Carefully place the exact calibration weight (not included) corresponding to the displayed value onto the center of the weighing pan.
- Wait for the display to show "PASS" and then return to normal weighing mode. This indicates successful calibration.
- Neħħi l-piż tal-kalibrazzjoni.
Nota: Use a high-quality, certified calibration weight for best results.
8. Manutenzjoni
- Tindif: Wipe the scale surface and weighing pan with a soft, damp cloth. Do not use abrasive cleaners or immerse the scale in water. The stainless steel weighing pan is removable for easier cleaning.
- Ħażna: When not in use for extended periods, store the scale in a dry, cool place, away from dust and extreme temperatures. Remove batteries if storing for a long time to prevent leakage.
