How to calibrate the light meter
Although calibration is different from verification, the personnel who perform the calibration should also undergo effective assessment and obtain the corresponding certificate of conformity. Only the certificate holder can issue the calibration certificate and calibration report, and only such certificates and reports are considered valid. . For calibration, you can find a local measurement institute or a third-party calibration unit, all of which must have the CNAS measurement qualification issued by the state.
