The precautions for using multi-channel weighing scales mainly include the following aspects:
1. Installation and environmental requirements
Ensure that the four corners of the weighing scale are stable and free from shaking, and that the conveyor scale platform is installed correctly without interference from other components.
The installation location should avoid interference from strong air convection (such as direct blowing from fans or air conditioners) to avoid affecting weighing accuracy.
The workspace should have low vibration, avoid temperature changes and direct sunlight, and maintain a constant room temperature.
2. Calibration and Testing
Static and dynamic calibration is required before use, and standard weights are used to detect static weight deviation, and the accuracy is verified through multiple dynamic tests.
Regularly manually inspect the materials in the non-conforming product storage bin and the qualified product collection container to verify the reliability of the removal action.
3. Parameter settings
Verify whether the device parameter settings are correct, including product length, standard values and upper and lower limits, belt speed, etc.
Ensure that the removal device is set correctly, including removal selection, action time, and delay.
4. Operating standards
Before starting, check if the weighing display is reset to zero. If it cannot be reset, clean the foreign objects on the weighing platform and reset to zero.
If the light blocking time is too long or the weight of the machine continues to be too large during work, the equipment will automatically stop and sound an alarm. Follow the prompts to handle it.
Overloading operation is strictly prohibited to avoid staying on the weighing platform for a long time.
5. Maintenance and upkeep
Regularly inspect the surfaces in contact with materials to ensure cleanliness and absence of residue.
Keep the windproof cover intact to avoid airflow interference with the weighing results.
For multi-channel weighing scales, it is necessary to regularly check the weighing units and rejection units of each channel to ensure their independent and normal operation.
6. Safety precautions
Operators need to maintain a safe distance from suspended objects to avoid accidental falling and causing injury.
It is prohibited to perform welding operations on the weighing platform or use it as a grounding wire.
By following the above precautions, the accuracy and reliability of the multi-channel weighing scale can be ensured, while extending the service life of the equipment.
