Reliable Measured Values through Calibration at Regular Intervals

DIN EN ISO 9001-9004 stipulates test equipment monitoring, if such equipment is relevant for product quality or is used for the preparation of assessments. This test equipment must be calibrated at regular intervals and traced back to national standards. Calibration involves the ascertainment and documentation of meter display deviation, traced back to a specific standard using a specified procedure. Depending upon how the respective device is used, a calibration interval of between 12 and 24 months is recommended. A combination including receiving report, adjustment and final report is also possible for GOSSEN meters.
