4. Iestatīšana
4.1. Barošanas avots
The SF-400D scale operates on two AA batteries (included) or an optional AC power adapter (not included).
- Atveriet bateriju nodalījuma vāciņu svaru apakšpusē.
- Ievietojiet divas AA baterijas, nodrošinot pareizu polaritāti (+/-).
- Aizveriet akumulatora nodalījumu.
- 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. Lietošanas instrukcijas
5.1. Pamata svēršana
- Nospiediet pogu IESLĒGTS/IZSLĒGTS 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 TĀRA pogu, lai nulli skalu.
- Nospiediet pogu REŽĪMS 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.
- Read the stable weight displayed on the LCD screen.
- Lai izslēgtu svarus, nospiediet un turiet IESLĒGTS/IZSLĒGTS button for a few seconds. The scale also features an auto shut-off function to conserve battery power.
5.2. Taras funkcija
The Tare function allows you to subtract the weight of a container, so only the contents are weighed.
- Novietojiet tukšu trauku uz svēršanas platformas.
- Pagaidiet, līdz displejs stabilizēsies un parādīsies konteinera svars.
- Nospiediet pogu TĀRA button. The display will reset to "0.00" (or "0.0").
- Pievienojiet traukā preces, kuras vēlaties nosvērt. Displejā tagad tiks rādīts tikai preču neto svars.
- To clear the tare, remove all items from the platform and press TĀRA 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.
- Turn on the scale and ensure it is zeroed.
- Nospiediet pogu PCS button. The display will show "PCS" and a sampfaila lielums (piemēram, "25", "50", "75", "100").
- Nospiediet pogu REŽĪMS 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 sampjūras līdaka.
- Place the exact number of sample items (e.g., 25 pieces) onto the weighing platform according to your selected sample lielums.
- Nospiediet pogu PCS vēlreiz, lai apstiprinātuample. 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 REŽĪMS pogu.
5.4. Kalibrēšana
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. attēls: 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.
- Nospiediet un turiet CAL pogu, pēc tam nospiediet IESLĒGTS/IZSLĒGTS 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.
