What to do if Netech UPM 2000 displays 'oL' error?
- MMichael BrooksAug 2, 2025
If your Netech Measuring Instruments displays an 'oL' error, it could indicate defective electronics or a damaged load cell. Immediately remove any excessive load from the load cell. Then, turn the unit off and back on to see if the error clears. If the error repeats, the unit must be returned to the factory for service. If this error occurs during a calibration check with the 100 gram check weight but the unit seems to read normally without the weight on, this indicates that the unit needs to be recalibrated.
