Avery Berkel L126 Calibration Guide: A Step-by-Step Walkthrough
The Avery Berkel L126 is a staple in the weighing industry, known for its reliability in industrial and retail environments. However, like any precision instrument, it requires periodic calibration to maintain accuracy and compliance with weights and measures regulations.
Whether you are troubleshooting "drift" or performing routine maintenance, this guide covers the essential steps for calibrating your Avery Berkel L126 indicator. Prerequisites Before You Begin
Calibration isn't just about pressing buttons; it’s about environment and equipment. Ensure you have the following:
Certified Test Weights: You will need weights roughly equal to the scale’s maximum capacity (e.g., if it’s a 15kg scale, have 15kg of certified weights ready).
Stable Surface: Ensure the scale is on a level, vibration-free surface.
Warm-up Time: Power on the unit for at least 15–30 minutes to allow the internal electronics to stabilize. Step 1: Entering Calibration Mode
To prevent accidental changes, the L126 usually requires a specific key sequence or a physical "cal-switch" adjustment.
Locate the calibration security switch (usually found behind a lead seal or a small panel on the underside/back of the indicator). Move the switch to the ON or CAL position.
Turn the scale on. The display should enter a setup menu (often indicated by a message like SETUP or F1). Step 2: Setting Capacity and Increments
Before the actual weight test, ensure the scale parameters are correct: Capacity: Set the maximum weight the scale should measure.
Division (d): Set the scale’s readability (e.g., 0.005kg or 0.01lb). Units: Choose between Kilograms (kg) or Pounds (lb).
Navigate through these settings using the TARE (to cycle) and ZERO (to confirm) keys. Step 3: Zero Calibration (Deadweight)
The scale needs to know what "zero" looks like with nothing on the platform. Ensure the scale platform is empty and clean. Select the Zero Calibration option from the menu.
Press ZERO to confirm. The display will usually countdown or flash while it captures the deadweight of the platter. Step 4: Span Calibration (Loading Weights) This step teaches the scale how to measure actual weight.
When the screen prompts (often showing LOAD or a flashing weight value), place your certified test weights on the center of the platform. avery berkel l126 calibration
Use the keypad to enter the exact value of the weights you have placed on the scale. Press ZERO or ENTER. The scale will process the "Span."
Once finished, the display should show a PASS or END message. Step 5: Exiting and Sealing Remove the weights from the platform.
Return the physical calibration switch to the OFF or LOCK position. The scale will reboot into normal weighing mode.
Test the accuracy: Place a known weight back on the scale to ensure the reading matches perfectly. Troubleshooting Common Issues
Error "Err 4": This often indicates that the calibration weight used was too small. Try using a weight closer to the scale's full capacity.
Unstable Readings: Check for drafts, vibrations, or the scale touching a nearby wall or object.
Inconsistent Spans: If the scale won't hold calibration, the load cell may be damaged or "binding" (hitting a mechanical stop). Important Regulatory Note
If you are using the Avery Berkel L126 for "Legal for Trade" applications (selling products by weight), calibration must be verified and sealed by a licensed weights and measures official or a certified service technician.

The Avery Berkel L126 is a robust, waterproof stainless steel digital indicator designed for basic weighing in harsh or hygienic environments. Calibrating this unit ensures it maintains its 6000-division performance accuracy. Calibration Pre-Check Before starting, ensure the following:
Stability: Place the scale on a flat, hard surface. Avoid carpet or uneven flooring.
Weights: You will need a certified calibration weight (commonly 10 lb or 5 kg, depending on your specific configuration). Cleanliness: Clear the platform of all debris or items. Step-by-Step Calibration Procedure Enter Calibration Mode:
Locate the SW1 button on the bottom of the scale unit. Use a pen or small screwdriver to press it. The display should show DIAG (Diagnose).
Press the Zero button twice until the display shows CAL (Calibration). Select this mode by pressing the Test button. Configure Units & Capacity:
Choose your unit of measure (e.g., ounces or kilograms) by pressing the Zero button until your desired unit appears. Confirm with the Test button.
The display may show a capacity value (like 160.1). If incorrect, use the Zero button to adjust and confirm with Test. Zero Calibration (Deadweight): The screen will read LOAD ZERO.
Ensure the platter is empty and press the Test button. Wait for the scale to stabilize. Span Calibration (Span Weight):
The display should now show LOAD 10 (or the equivalent weight for your setup).
Gently place the required calibration weight in the center of the scale platform.
Press the Test button. The scale will process the calibration for several seconds. Finalize: When the display reads DONE, remove the weight.
Press the Test button to restart the scale and return to normal weighing mode. Troubleshooting & Maintenance Warning: Do not place weights on the scale
Error Messages: If calibration fails, ensure the load cells are not obstructed and the platform moves freely.
Verification: After restarting, place a known weight on the scale to verify the reading is now accurate.

Are you calibrating the scale for legal-for-trade use, or is this for internal weight checks? L126 - Eltak
Cause: Load cell wear or corner loading errors. Fix: Perform a Corner Adjustment . Place the test weight on each corner of the platform. If one corner is significantly off, the load cell is physically bent. If all corners are off equally, redo the span calibration with a smaller weight (e.g., 5kg) first, then the full weight.
This procedure covers a "Hard Calibration" (Span Calibration) for the Avery Berkel L126. It assumes you have physical access to the internal PCB.
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 initiating the calibration sequence, gather the following:
Warning: Do not place weights on the scale during the zero calibration stage. Ensure the platform is completely clean and free of debris.
Once the weights have been accepted:
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
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.
Q: Can I use a dumbbell or a bag of rice for calibration? A: No. Household weights are never accurate enough. The L126 is precise to 2g or 5g. You need certified Class M1 or F2 test weights.
Q: My L126 shows "0" when empty, but -50g when I turn it on the next day. A: This is temperature drift. If a warm-up zero doesn't fix it, you need to perform the "Zero Calibration" step again in the ambient operating temperature.
Q: What is the difference between Calibration and Configuration? A: Calibration sets the physical weight-to-electronics ratio. Configuration sets the scale’s ID, baud rate, and price lookups. Do not confuse the calibration menu with the "FUNC" configuration menu.
Q: I lost the calibration manual. Can I find the factory default values? A: The L126 does not have "default values" because every load cell is different. You must perform the calibration procedure with physical weights. There is no shortcut code.
