For Trade Use: If your L126 is used for trade (charging customers by weight), it is likely a "Legal for Trade" device. In most jurisdictions, only certified technicians with calibrated traceable weights can perform official calibrations. Unauthorized calibration may violate weights and measures laws and result in fines.
Before beginning the calibration process, ensure the following:
Most L126 units have a calibration switch located inside the base. To access it:
Most modern retail scales like the L126 utilize a multi-point calibration (linearization) to ensure accuracy across the entire weighing range. avery berkel l126 calibration
Step A: Zero Point Calibration
Step B: Span Calibration (Gain)
Step C: Additional Points (If Applicable) Some configurations may request a mid-range weight (e.g., 3kg). If the display prompts a different number, place that specific weight and confirm. For Trade Use: If your L126 is used
↑/↓ and press Enter.To extend the time between calibrations on your Avery Berkel L126, follow this schedule:
| Frequency | Action | | :--- | :--- | | Daily | Clean the platter and housing. Check for level using the bubble vial. | | Weekly | Perform a corner load test (place a weight in each quadrant). | | Monthly | Check the internal battery (replaces the real-time clock and calibration RAM). A low battery can cause calibration loss. | | Annually | Full recertification by a third-party metrology lab. |
It is crucial to distinguish between Calibration Verification (checking) and Calibration Adjustment (changing). Most L126 units have a calibration switch located
Most retailers can perform a Daily Verification using a legal-for-trade test weight:
Calibration Adjustment (the process described in Part 3) should only be done by a "Weights and Measures Certified" technician or an in-house service department with traceable weights.
If the procedure fails, you are not alone. Here are the most frequent issues:
