5.1 Osnovno tehtanje

1. Pritisnite VKLOP/IZKLOP button to turn on the scale. The display will show "88888" and then "0.00" (or "0.0" depending on the unit).
2. If the display does not show zero, press the TARA gumb za ničlo lestvice.
3. Pritisnite NAČIN button to select your desired weighing unit (g, oz, ct, dwt, gn, T).
4. Gently place the item(s) to be weighed on the center of the stainless steel platform.
5. Odčitajte stabilno težo, prikazano na LCD-zaslonu.
6. Za izklop tehtnice pritisnite in držite VKLOP/IZKLOP button for a few seconds. The scale also features an auto shut-off function to conserve battery power.

5.2. Funkcija tare

The Tare function allows you to subtract the weight of a container, so only the contents are weighed.

1. Na tehtalno ploščad postavite prazno posodo.
2. Wait for the display to stabilize and show the container's weight.
3. Pritisnite TARA gumb. Prikaz se bo ponastavil na "0.00" (ali "0.0").
4. Add the items you wish to weigh into the container. The display will now show only the net weight of the items.
5. To clear the tare, remove all items from the platform and press TARA again if the display does not return to zero automatically.

5.3. Piece Counting Function (PCS)

This function is useful for counting multiple identical items.

1. Turn on the scale and ensure it is zeroed.
2. Pritisnite PCS button. The display will show "PCS" and a sample size (e.g., "25", "50", "75", "100").
3. Pritisnite NAČIN button to cycle through the available sample sizes (25, 50, 75, 100 pieces). Select the sample size that matches the number of items you will place on the scale for sampling.
4. Place the exact number of sample items (e.g., 25 pieces) onto the weighing platform according to your selected sample velikost.
5. Pritisnite PCS ponovno pritisnite gumb za potrditevample. The display will now show the number of pieces.
6. You can now add more items of the same type, and the scale will display the total count.
7. To exit the counting mode, press the NAČIN gumb.

5.4. Umerjanje

Calibration ensures the accuracy of your scale. It is recommended to calibrate the scale periodically or if you suspect inaccurate readings. You will need a known calibration weight (e.g., 500g) for this process.

Slika 4: SF-400D display showing "CAL" during calibration mode. This image illustrates the scale's screen indicating it is in calibration mode, prompting the user to place a calibration weight.

1. Ensure the scale is on a stable, level surface and turned off.
2. Pritisnite in držite KAL in nato pritisnite VKLOP/IZKLOP button simultaneously. Release both buttons when the display shows "CAL".
3. The display will then show a flashing weight value (e.g., "500.00g"). This is the required calibration weight.
4. Place the exact calibration weight (e.g., 500g) onto the center of the weighing platform.
5. Wait for the display to stabilize and show "PASS" or return to normal weighing mode. This indicates successful calibration.
6. Remove the calibration weight. The scale is now calibrated and ready for use.
7. If "FAIL" or an error message appears, repeat the calibration process.

6. Vzdrževanje

6.1. Čiščenje

• Površino tehtnice obrišite z mehko, rahloamp krpo.
