🛠️ DIY Troubleshooting for Chinese Scales

Sometimes, our trusty measurement helpers — Chinese electronic scales — can run into minor issues. Don’t worry! In most cases, you can fix them yourself at home. This article will guide you through the most common problems and how to solve them.

💡 Problem: Power indicator does not light up

If you turn on the scale and the power indicator doesn’t light up, check the following possible causes:

1. 🔌 The power cord is not connected to the scale or outlet.
2. 🔌 Loose plug connection. Try unplugging and plugging it back in.
3. ⚠️ The power cord is damaged or broken. Carefully inspect for visible defects.
4. ⚠️ The fuse has blown (if your model has one).

🛠️ Solution:

• ✅ Replace the power cord if damaged.
• ✅ Replace the fuse with an identical one if you’re sure it’s the issue.

📉 Problem: Display shows "Lb" and scale shuts down

If the display shows "Lb" with a warning signal and the scale shuts off, this usually points to power issues:

1. 🔋 Low battery charge.
2. 🔋 Prolonged use without charging may have caused deep discharge.

🛠️ Solution:

• ✅ Plug the scale into a power source and charge it for the recommended time (usually around 7 hours).
• ✅ Check the power adapter’s condition by testing with another outlet or using a known-working adapter.

⚖️ Problem: Weight readings are unstable

If weight readings keep changing and won’t stabilize, check the following:

1. 🔋 Low battery charge (especially on battery-powered models).
2. 💧 Moisture has entered the scale’s body.
3. 🔌 Loose connection between the main unit and the weighing platform.

🛠️ Solution:

• ✅ Charge the battery as recommended.
• ✅ If moisture is suspected, turn off the scale and let it dry thoroughly in a warm, dry place.
• ✅ Check and reconnect the plug between the unit and platform if needed.

🛑 Problem: Display shows "FULL" and alarm sounds

The "FULL" message usually doesn’t indicate overload, but rather a connection issue between the scale’s parts:

1. 🔌 Loose connection between the main unit and weighing platform.
2. ⚠️ Damaged cable between the main unit and platform.

🛠️ Solution:

• ✅ Check and secure the connection plug.
• ✅ Carefully inspect the cable for visible damage. Repair or replace it if needed.

🌡️ Problem: Incorrect weight readings (too high or low)

Incorrect weight readings may be caused by:

1. 🔌 Loose connection between main unit and platform.
2. ⚙️ Scale calibration is off.

🛠️ Solution:

• ✅ Check and secure the connection plug.
• ✅ Calibrate the scale according to your model’s manual. General calibration steps:
  1. Turn on the scale.
  2. Find and press the "CAL" or "MODE" button and hold it for a few seconds.
  3. "CAL" or a calibration weight value may appear on the display.
  4. Place the correct calibration weight on the platform.
  5. Wait for the calibration to complete (the display may show "PASS" or another confirmation).
  6. Remove the weight and turn off the scale.
