Calibration Ask HOZAN dealer for calibration and adjustment. We are able to issue test data, calibration certificates and traceability charts on request. You can perform calibration (judging if the unit is correct) and adjustment by yourself, but it is not recommended for precise measuring and we are not able to guarantee its result.
