Your Weighmax NJ800 scale is factory calibrated. However, if you notice inaccuracies over time, recalibration may be necessary.

Please refer to the specific calibration instructions that may be printed on the scale itself or contact customer support for detailed guidance, as calibration procedures can vary slightly between models.
