Calibrating dynamic checkweighers on the production line is a crucial step to ensure their accuracy and reliability. Below is a general calibration process that can be adjusted according to the specific model and guidelines provided by the manufacturer:
Step One: Preparation
- Check Equipment Status: Ensure the dynamic checkweigher is in normal working condition without any damages or abnormalities.
- Clean Workspace: Clear the weighing platform and the surrounding area, ensuring no debris or dirt that could affect measurements.
Step Two: Zero Load Calibration
- Remove All Objects: Ensure there are no objects on the weighing platform, leaving the dynamic checkweigher in an unloaded state.
- Perform Zero Calibration: Select the zero calibration option in the device menu or control panel to adjust the dynamic checkweigher to zero.
Step Three: Calibrate System Parameters
- Input Standard Values: Input standard mass values into the dynamic checkweigher system based on the manufacturer’s specifications.
- Perform Calibration: Initiate the calibration procedure, allowing the system to automatically adjust internal parameters to match standard values.
Step Four: Verify Calibration Results
- Place Standard Objects: Position objects with known masses on the weighing platform.
- Compare Results: Check if the displayed weight on the dynamic checkweigher matches the actual mass of the standard objects. Calibration should minimize differences between measurement results and actual mass.
Step Five: Adjust and Repeat
- Adjust Parameters: If any discrepancies are detected, follow the manufacturer’s instructions to adjust parameters and reduce differences.
- Repeat Calibration: Repeat the above steps until the dynamic checkweigher provides accurate measurements for various mass values.
Step Six: Record and Certification
- Record Calibration Data: Document the date, time, standard mass values used, and adjustment parameters for each calibration.
- Generate Calibration Certificate: Create a calibration certificate document, detailing the calibration process and results, in accordance with relevant standards and regulations.
Considerations:
- Regular Calibration: Establish a regular calibration schedule based on equipment usage frequency and manufacturer recommendations.
- Follow Manufacturer Guidelines: Strictly adhere to the calibration guidelines provided by the manufacturer to ensure the effectiveness and compliance with specified standards.
- Training for Operators: Ensure operators receive proper training on how to correctly operate and calibrate dynamic checkweighers.
- External Professional Services: For complex dynamic checkweighers, consider periodically hiring external professional services for calibration to ensure the highest level of accuracy and performance.
By following the above steps and considerations, you can ensure that dynamic checkweighers on the production line maintain a high level of accuracy, providing reliable weight measurements for the production process.
