5. Operating Instructions

Learn how to use your scale for accurate measurements:

• Power On/Off: Press the yellow 'on/off/tare' button briefly to turn the scale on. To turn the scale off, press and hold the 'on/off/tare' button until the display turns off.
• Zeroing the Scale: Before placing any item on the scale, ensure the display reads '0.0'. If it does not, press the 'on/off/tare' button briefly to zero the scale. This ensures accurate measurement.
• Weighing an Item: Gently place the item to be weighed on the center of the scale platform. Wait for the digital display to stabilize and show the final weight.
• Tare Function: To weigh items in a container, first place the empty container on the scale. Press the 'on/off/tare' button to zero the display. Then, place the items to be weighed into the container. The display will now show only the net weight of the items, excluding the container's weight.
• Unit Conversion: The scale can measure in pounds (lb) or kilograms (kg). The display will indicate the current unit. If a dedicated unit conversion button is present (not explicitly visible in the main image), press it to switch between 'lb' and 'kg'.

6. Maintenance

Proper care will extend the life and accuracy of your scale:

• Cleaning: Clean the scale with a soft, slightly damp cloth. Do not use abrasive cleaners, solvents, or immerse the scale in water.
• Storage: Store the scale in a dry, cool place away from direct sunlight and extreme temperatures when not in use.
• Power Adapter: Periodically inspect the power adapter and its cable for any signs of damage. Discontinue use if damage is found and replace with an approved adapter.

7. Troubleshooting

If you encounter issues with your scale, refer to the following common problems and solutions:

• Scale does not turn on:
  • Ensure the power adapter is securely connected to both the scale and a working electrical outlet.
  • Check if the power outlet is functional by plugging in another device.
• Inaccurate or fluctuating readings:
  • Verify that the scale is placed on a completely stable, level, and vibration-free surface.
  • Ensure no objects are touching the scale platform or the display unit other than the item being weighed.
  • Perform a zeroing operation before weighing.
• Display shows 'Err' or 'OL':
  • This typically indicates an overload. Remove the item from the scale immediately. The scale's maximum capacity is 310 pounds.
  • If the error persists after removing the item, power cycle the scale (turn off, then on).
