4. Konfigurazioa
4.1. Elikatze-iturria
The SF-400D scale operates on two AA batteries (included) or an optional AC power adapter (not included).
- Open the battery compartment cover on the underside of the scale.
- Sartu bi AA pila, polaritate zuzena ziurtatuz (+/-).
- Itxi bateriaren konpartimendua.
- Alternatively, connect a compatible AC power adapter (6V, amperage not specified in product details, consult manufacturer if needed) to the power port.
4.2. Placement and Leveling
For optimal accuracy, the scale must be placed on a stable, flat, and level surface.
- Place the scale on your desired weighing surface.
- Observe the integrated bubble level.
- Adjust the four adjustable legs on the bottom of the scale by rotating them until the bubble is centered within the level indicator.
5. Funtzionamendu-argibideak
5.1. Oinarrizko pisaketa
- Sakatu ON/OFF button to turn on the scale. The display will show "88888" and then "0.00" (or "0.0" depending on the unit).
- If the display does not show zero, press the Tare botoia eskala zerorako.
- Sakatu MODUA button to select your desired weighing unit (g, oz, ct, dwt, gn, T).
- Gently place the item(s) to be weighed on the center of the stainless steel platform.
- Irakurri LCD pantailan bistaratzen den pisu egonkorra.
- Balantza itzaltzeko, sakatu eta eutsi botoiari ON/OFF button for a few seconds. The scale also features an auto shut-off function to conserve battery power.
5.2. Tara funtzioa
The Tare function allows you to subtract the weight of a container, so only the contents are weighed.
- Jarri ontzi huts bat pisatzeko plataforman.
- Wait for the display to stabilize and show the container's weight.
- Sakatu Tare button. The display will reset to "0.00" (or "0.0").
- Add the items you wish to weigh into the container. The display will now show only the net weight of the items.
- Tara garbitzeko, kendu elementu guztiak plataformatik eta sakatu Tare again if the display does not return to zero automatically.
5.3. Pieza zenbaketa funtzioa (PCS)
This function is useful for counting multiple identical items.
- Turn on the scale and ensure it is zeroed.
- Sakatu PCS button. The display will show "PCS" and a samptamaina (adibidez, "25", "50", "75", "100").
- Sakatu MODUA 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.
- Jarri s kopuru zehatzaample items (e.g., 25 pieces) onto the weighing platform according to your selected sample tamaina.
- Sakatu PCS botoia berriro sakatu s baieztatzekoample. The display will now show the number of pieces.
- You can now add more items of the same type, and the scale will display the total count.
- To exit the counting mode, press the MODUA botoia.
5.4. Kalibrazioa
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.

4. irudia: 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.
- Ensure the scale is on a stable, level surface and turned off.
- Eduki sakatuta CAL botoia, eta sakatu ON/OFF button simultaneously. Release both buttons when the display shows "CAL".
- The display will then show a flashing weight value (e.g., "500.00g"). This is the required calibration weight.
- Place the exact calibration weight (e.g., 500g) onto the center of the weighing platform.
- Wait for the display to stabilize and show "PASS" or return to normal weighing mode. This indicates successful calibration.
- Remove the calibration weight. The scale is now calibrated and ready for use.
- If "FAIL" or an error message appears, repeat the calibration process.
6. Mantentzea
