1. Power On/Off:
   • Press the Power button () to turn the scale ON. The display will show "88888" then "0.0" with the current unit.
   • Press and hold the Power button for 3 seconds to turn the scale OFF.
2. Unit Selection (Kg/Lb/N):
   • With the scale ON and displaying "0.0", press the HOLD/UNIT button to cycle through the available weighing units: Kilograms (kg), Pounds (lb), and Newtons (N).
3. Tare Function:
   • To weigh items in a container, first hang the empty container on the hook.
   • Press the TARE button. The display will reset to "0.0".
   • Add the items to be weighed into the container. The display will show the net weight of the items.
4. Hold Function:
   • While weighing a load, press the HOLD/UNIT button to lock the current weight reading on the display. The "HOLD" indicator will appear.
   • Press the HOLD/UNIT button again to release the hold function and return to live weighing.
   • Note: This function holds the weight displayed at the moment the button is pressed, not necessarily the maximum weight achieved during the lift.
5. Weighing Procedure:
   • Ensure the scale is ON and displaying "0.0" in your desired unit.
   • Carefully attach the item to be weighed to the bottom hook.
   • Allow the load to stabilize. The display will show the weight. The reading stable time is typically less than 10 seconds.
   • Remove the load once the reading is taken.
6. Auto Power Off:
   • The scale will automatically turn off after approximately 3 minutes of inactivity to conserve battery life. This feature cannot be adjusted or disabled.

Maintenance

• Cleaning: Wipe the scale with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and electronic components. Avoid getting water inside the unit.
• Storage: Store the scale in a dry, cool place away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries to prevent leakage.
• Battery Replacement: When the battery indicator appears on the display, replace both AAA batteries promptly to ensure accurate readings and proper operation.

Troubleshooting

Scale does not turn on:

Check battery installation. Ensure batteries are inserted with correct polarity and are fully charged. Replace batteries if necessary. Ensure battery contacts are clean and free from corrosion.

Inaccurate readings:

Ensure the scale is suspended stably and not swinging. Verify the load is not touching any other surfaces. Check if the scale has been overloaded. Perform a tare operation before weighing.

Scale turns off unexpectedly:

This may be due to the 3-minute auto-off feature if no activity is detected. If it turns off during active weighing, check battery contact and ensure batteries are securely seated and not loose.

Display shows "O-Ld" or similar:

This indicates an overload condition. Remove the load immediately to prevent damage to the scale. Do not exceed the 300 kg / 600 lbs capacity.
