| Symptom / Error Type | Common Cause(s) | Troubleshooting / Potential Solution(s) | | :--- | :--- | :--- | | | Power supply disconnected, blown fuse | Check all power connections. Inspect and replace any blown fuses. Ensure the facility's circuit breaker hasn't tripped. | | Inaccurate or Unstable Weight | Mechanical binding, load cell malfunction, environmental vibration, incorrect calibration | Ensure the scale is free from mechanical obstructions. Check the load cell connections and perform a load cell test. Use the TraxDSP™ filter to dampen vibrations, or recalibrate the scale. | | Communication Error (Serial) | Incorrect serial port settings, faulty cable | Verify the baud rate, data bits, parity, and stop bits match the connected device. Test with a known-good cable or inspect the existing one for damage. | | "ERR 1" Error Code | Issue related to calibration | The user manual recommends checking the calibration setup. Often, a recalibration procedure can resolve this error. | | "ERR 2" Error Code | Typically indicates a sensor malfunction or other system error | Refer to the user manual's error code table. A system reboot may clear temporary issues. | | Controller Freezing / Locking Up | Software glitch or hardware conflict | The most common first step is to perform a power cycle (reboot). If the issue persists, contact qualified service personnel. |
