- Eight Common Causes and Corresponding Solutions:
- Cause 1: Sensor Failure (Most Common) → Phenomenon: Weighing data fluctuates and has large errors; Solution: Use a multimeter to measure the sensor resistance (input resistance 380±20Ω, output resistance 350±5Ω). If the resistance is abnormal, replace the sensor; Weight Worth provides original sensors of the same model (complying with OIML standards) and supports fast delivery overseas (arrival in most regions within 7-15 days) to ensure accuracy matching.
- Cause 2: Expired Instrument Calibration → Phenomenon: All weighing values are generally high or low; Solution: Calibrate according to the instrument manual (taking the WEIGHT WORTH instrument as an example: long press the "Calibration" key → enter the password → load the standard weight → confirm calibration, supporting English operation interface), or contact the local metrology agency (WEIGHT WORTH can recommend cooperative overseas metrology agencies) for verification to ensure compliance with local standards.
- Cause 3: Foreign Object Jamming in the Weighbridge Body → Phenomenon: Unstable weighing value and difficulty in returning to zero; Solution: Regularly clean the stones and soil between the weighbridge body and the foundation (clean once a week in sandy and windy overseas areas), and check whether the limit device is too tight (2-3mm gap should be reserved); if the limit device is rusted, anti-rust oil can be applied.
- Cause 4: Junction Box Damp/Oxidation → Phenomenon: Data drift and large corner errors; Solution: Open the junction box, dry it with a hair dryer on cold air (desiccant can be placed in the junction box in humid overseas areas and replaced once a month), polish the oxide layer on the terminal blocks with sandpaper, and apply conductive paste (to ensure conductivity, complying with international electrical standards).
- Cause 5: Unstable Power Supply Voltage → Phenomenon: The instrument display flickers and the weighing is inaccurate; Solution: Install a voltage stabilizer (output voltage 220V±5%, complying with overseas voltage standards, such as selecting the corresponding model for 110V areas), and avoid sharing the same power supply with high-power equipment (such as cranes and electric welders); a high-precision voltage stabilizer should be selected in some overseas regions with large voltage fluctuations.
- Cause 6: Instrument Failure → Phenomenon: Garbled display and no response; Solution: Restart the instrument, and if it is ineffective, replace the instrument main board; WEIGHT WORTH provides original instrument accessories (supporting English interface), and overseas customers can replace them by themselves (a video tutorial is provided) or have the cooperative service team replace them on-site.
- Cause 7: Vehicle Eccentric Loading → Phenomenon: Different weighing values of the same vehicle at different positions; Solution: Guide the driver to park the vehicle in the center of the weighbridge body to ensure that the wheels are completely on the weighbridge; in overseas multi-language environments, multi-language signboards (such as English and local languages) can be set beside the weighbridge to remind drivers to park correctly.
- Cause 8: Environmental Interference → Phenomenon: Data fluctuates, and there are high-magnetic field equipment nearby; Solution: Stay away from equipment such as transformers and electric welders, or install electromagnetic shielding devices (complying with IEC electromagnetic compatibility standards); if there are high-magnetic field equipment in overseas factories, the weighbridge installation location should be planned in advance to avoid interference.
- Quick Troubleshooting Skills: First check simple factors (foreign objects, power supply, vehicle position), then check complex factors (sensors, junction boxes, instruments); the "replacement method" (replacing with spare sensors for testing) can be used to determine the fault point; WEIGHT WORTH provides an English fault troubleshooting manual, and overseas customers can troubleshoot step by step according to the manual to improve efficiency.
- Preventive Measures: Clean foreign objects on the weighbridge body every month, check the waterproofing of the junction box and the status of sensors every quarter (increase the inspection frequency in harsh overseas environments), and conduct a comprehensive calibration every year; WEIGHT WORTH can provide a "regular maintenance package" (including overseas on-site maintenance services) to reduce the failure rate and extend the service life of the equipment.
