The Calibration Procedures compares scale readings against certified reference weights. Technicians test multiple points throughout the weighing range and adjust internal parameters to minimize error.

Calibration vs. Verification

Legal-for-Trade Compliance requires the devices to bear NTEP Certificates of Conformance and undergo rigorous testing.

Calibration Process

• Adjusts scale parameters to achieve specified accuracy
• Requires breaking security seals
• Only trained technicians should perform
• Legal-for-trade devices require licensed providers

Verification Process

• Confirms scales operate within acceptable tolerances
• Does not involve adjustments
• Uses certified test weights
• Operators can perform between formal calibrations

Facilities must maintain calibration records and implement verification schedules.

Troubleshooting Common Errors

1. Zero Drift Issues

Clean any buildup from under the platform and remove debris causing mechanical binding. Allow the system to stabilize the temperature and verify that nothing interferes with normal operation.

2. Overload Errors

Remove excess weight immediately to prevent damage. Check for mechanical obstructions and inspect load cell mounting hardware for binding. Ensure loads stay within rated capacity.

3. Communication Failures

Verify all cable connections are secure and undamaged. Ensure communication settings match between devices. Power cycle both the scale and connected equipment as needed.

4. Inaccurate Readings

Perform verification tests using certified weights across the operational range. Consider recalibration if the load cell remains sound. Contact a professional service for persistent accuracy issues.
