🛠️ Troubleshooting and Calibrating OXI, ACS, TCS Scales (30–600 kg) at Home
⚠️ Common Issues with OXI, ACS, TCS Scales and How to Fix Them
Let’s go over some typical problems that may occur with your OXI, ACS, or TCS scales (30kg to 600kg capacity) and how you can troubleshoot them yourself.
🔌 Power Indicator Doesn't Light Up
- Check if the power cord is securely connected to the scale and power outlet.
- Make sure the plug and socket are not damaged.
- Inspect the power cord for breaks or bends.
- Check the fuse (if your model has one).
Solution: a. Try using a known working power cord. b. Replace the fuse with one of the same specifications.
🔋 Display Shows "Lb" and Shuts Down
- The battery might be low and needs recharging.
- Prolonged use without charging may have deeply discharged the battery.
Solution: a. Plug the scale into the power outlet and charge it for the recommended time (usually 7 hours). b. Check the power supply for proper voltage output.
⚖️ Unstable Weight Readings
- Check battery level — low voltage can cause instability. Also, ensure the scale is not in a humid environment.
- Inspect the connector between the head unit and platform for loose contact or dirt.
Solution: a. Charge the battery for 7 hours. b. Disconnect and reconnect the connector, ensuring a firm fit. Clean the contacts if needed.
🛑 "FULL" Message and Alarm Sound
- Check the connection between the head unit and the weighing platform.
- The cable may be damaged or disconnected.
Solution: a. Carefully inspect the cable for damage and ensure tight connector contact.
📉 Weight Reading Too High or Too Low
- Check the connection between the head unit and the platform.
- Calibration may have been lost.
Solution: a. Check connection integrity. b. Perform scale calibration (see instructions below).
⚙️ Calibration of OXI, Planeta Vesov, Tandem Scales (Code Selection)
OXI, Planeta Vesov, and Tandem scales come in various versions, but they often use similar processors. Calibration codes may differ, so you need to try the right one from the list below. The rest of the calibration procedure is usually the same.
🔑 Calibration Codes (Possible Options):
3658, 2068, 2069, 7247, 8818, 8518, 5867, 1068, 7561, 9848, 2038, 1589 (for lower models)
and with a dot (for higher models): 36.58, 20.68, 20.69, 72.47, 88.18, 85.18, 58.67, 10.68, 75.61, 98.48, 20.38, 15.89
📝 Calibration Instructions:
- Turn on the scale. The main display should show "0.000".
- Enter a calibration code (try codes from the list in order).
- Press the TARE button. A half-zero "0" may appear in the top-right corner of the second display (indicating entry into calibration mode).
- Press the 1 button.
- Press the TARE button again. The third display may show "----".
- Place an accurate calibration weight (50–100 kg) on the platform.
- Enter the exact calibration weight value (e.g., 50.00 if using a 50kg weight).
- Press the TARE button.
- Enter the maximum capacity of your scale (e.g., 100.00 or 300.00). In some models, the decimal point may be omitted.
- Press the TARE button.
- Enter the graduation value (usually 05).
- Press the TARE button.
- Turn off the scale.
- Remove the calibration weight.
- Turn the scale back on and verify calibration accuracy.
Note: Be careful when entering zeros and decimal points. Incorrect input may lead to inaccurate calibration.
