Completely remove the physical calibration weights from the platform. Press the button one final time.
There are two main methods for the L126. Method A (Dip Switch) is for older units; Method B (Keypad) is for newer firmware. Try Method B first.
If the procedure fails, you are not alone. Here are the most frequent issues:
Do not place weights on the scale during the zero calibration stage. Ensure the platform is completely clean and free of debris. avery berkel l126 calibration
Place a weight representing roughly 1/3 of max capacity on each of the four corners of the platter. The readings should match within a minute tolerance fraction. Troubleshooting Common Calibration Errors Error Code / Symptom Possible Cause ERR 0 or CAL ERR Unstable environment or vibration. Relocate to a solid bench; eliminate drafts. Scale won't register weight changes Defective or disconnected load cell. Check internal cable connections to the PCB. FAIL during Span Incorrect weight value entered. Ensure the value typed matches the weights on the pan. Settings don't save Hardware calibration switch is locked. Toggle the internal calibration jumper/switch back to open.
: The display will show a default weight value (such as 160.1 ). If this does not match your intended calibration weight, use the Zero button to adjust it and confirm with the Test button .
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. Completely remove the physical calibration weights from the
: 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" .
You did not exit calibration mode properly, or there is a weak internal battery (RTC battery). Fix: Repeat the calibration, but after pressing "ENTER" or "PRICE 2", wait 10 seconds before turning off the power. If the issue persists, replace the CR2032 battery on the main PCB.
Place the scale on a flat, rigid, and vibration-free surface. Method A (Dip Switch) is for older units;
If the scale allows for alternative weight values, use the keypad to adjust the displayed value to match your physical weights.
