To calibrate an Avery Berkel L126 digital scale, you must access the internal service mode and use a certified calibration weight (typically 10 lbs or its metric equivalent). Calibration Steps
Enter Diagnostic Mode: Locate the SW1 button (calibration switch) on the bottom of the scale. Use a pen or small screwdriver to press it. The display should read "DIAG".
Access Calibration: Press the Zero button twice until the screen displays "CAL". Press the Test button to select this mode.
Select Units: Use the red Zero button to scroll through units until your preferred measure (e.g., "ounce" or "kg") appears. Confirm by pressing the blue Test button.
Set Capacity: The display will show a default capacity (like "160.1"). If this is incorrect for your model, use the Zero button to adjust it and confirm with the Test button.
Zero Calibration (No Load): Ensure the scale is empty and on a flat surface. When the screen says "Load Zero", press the Test button. The scale will register the empty weight.
Span Calibration (Apply Weight): The display will prompt for a weight (e.g., "Load 10"). Gently place the 10 lb calibration weight in the center of the platform. Press the Test button.
Finalize: The screen will briefly show it is calibrating and then display "Done". Remove the weight and press the Test button to restart the scale in normal weighing mode. Essential Equipment
Calibration Weight: A known, certified mass is required for accuracy.
Small Tool: A screwdriver or pen to trigger the recessed SW1 switch.

Master Guide: Calibrating the Avery Berkel L126 Weight Indicator
In high-stakes retail and industrial environments, accuracy isn't just a preference—it's a requirement. The Avery Berkel L126
is a robust, stainless steel, waterproof digital indicator built for harsh environments, but even the toughest hardware requires regular calibration to maintain its 6,000 division performance.
This guide breaks down the technical steps to calibrate your
, ensuring your business stays compliant and your measurements remain precise. 1. Preparation and Tools
Before starting, ensure your scale is on a flat, hard surface to avoid uneven weight distribution. You will need: A small screwdriver or pen to access the internal switch.
Standardized calibration weights (typically 10 lbs or as specified by your maximum capacity). A clear platform with no items or debris. 2. Step-by-Step Calibration Procedure
uses a specific sequence to enter its internal diagnostic and calibration modes.
Access Setup Mode: Locate the SW1 button on the bottom of the scale. Use your screwdriver to press it. The display should read "D I A G" (Diagnose).
Select Calibration: Press the Zero button twice until the display changes to "C A L". Confirm this selection by pressing the Test button.
Choose Units: Use the Zero button to scroll through units (e.g., "ounce", "lb", "kg"). Once your preferred unit appears, select it with the Test button. To calibrate an Avery Berkel L126 digital scale,
Confirm Capacity: The scale may display a capacity value (e.g., "160.1"). If it is incorrect, use the Zero button to adjust it and the Test button to confirm.
Set Zero Point: The display will prompt "load zero". Ensure the platform is completely empty and press the Test button.
Load Calibration Weight: The display will then read "load 10" (or another specific weight value). Gently place your standard calibration weight on the center of the platform and press the Test button.
Finalize: The scale will process the weight. Once it displays "done", remove the weight and press the Test button to restart the scale in normal weighing mode. 3. Troubleshooting Common Issues
Error 999: Often seen on related models like the L115, this indicates a lock-up. Resolving it typically requires entering setup mode to clear existing errors before attempting a full recalibration. Drifting Readings
: Ensure the scale is away from strong vibrations or air currents. If readings fluctuate, check the load cell connections for moisture, even though the is IP67-rated.
Incorrect Increments: You can adjust the scale increments and maximum capacity within the Service Set-up Mode if the standard calibration does not yield the required precision. 4. Professional Maintenance
For businesses requiring legal-for-trade certification, manual calibration is often just the first step. You may need to Log a Service Call with Avery Berkel Technical Support to have a certified technician seal the device.
Calibration Guide: Avery Berkel L126 Scale
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.
This guide provides an informative overview of the calibration process for the Avery Berkel L126. The display will usually flash 0 or prompt
Most modern retail scales like the L126 utilize a multi-point calibration (linearization) to ensure accuracy across the entire weighing range.
Step A: Zero Point Calibration
0 or prompt for a zero calibration.Step B: Span Calibration (Gain)
6000 or 15000). This represents the required test weight in grams.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.
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. |
To reduce how often you need to perform an avery berkel l126 calibration, adopt these habits:
It is crucial to distinguish between Calibration Verification (checking) and Calibration Adjustment (changing).
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.
While the steps above are straightforward, there are times to put the screwdriver down:
A professional service usually costs $150-$250, which includes cleaning, calibration, and a certificate of conformance. Given the cost of a new L126 (~$800-$1200), this is often worth it.
