If you see any of these error indicators after a calibration, double-check your load cell connections and ensure the scale platform is mechanically sound.

RS232 serial output, PLC/data logger analog interfaces (4-20mA, 0-10V)

Gently place your certified calibration weights directly in the center of the platform.

The Avery Berkel L126 is a robust, label-printing scale commonly used in retail environments such as delicatessens, bakeries, and butcher shops. Over time, mechanical wear, temperature changes, or relocation can cause the scale to drift, resulting in inaccurate weights. Calibration restores the scale to factory accuracy.

Before beginning, assemble the following tools:

(often on the bottom or back) using a small tool; the display should show "DIAG". Access Calibration

Once complete, it will show a success message or display the active calibrated weight.

Move the scale to a stable bench; shield it from air currents. Err 5 / Fail Incorrect calibration weight used.

At least annually, after moving the scale, or if the scale shows inconsistent readings. Preparation: What You Need

Completely clear the scale platform of all items, hooks, debris, or moisture attachments.

The Avery Berkel L126 typically uses a "hidden" key sequence to enter the setup or calibration mode. While software versions can vary, the standard procedure is as follows:

This report outlines the step-by-step procedure for calibrating the Avery Berkel L126 digital scale. The L126 series is commonly used in food processing and industrial environments. Calibration is necessary when the scale shows inaccuracy, after moving the unit, or as part of routine maintenance schedules. This guide covers the "Zero" and "Span" calibration method using certified test weights.

Meets Weights and Measures statutory requirements for commercial trade transactions.

The display should show DIAG (Diagnostics). Press the ZERO (Red) button twice. The display should now read CAL (Calibration).

Over time, environmental factors and mechanical wear can cause a scale's accuracy to drift. Regular calibration offers several critical benefits:

By following this guide, you can ensure your delivers trustworthy performance, supporting the accuracy and reliability that industrial operations depend on every day.
