    5. OPERATING INSTRUCTIONS 5-1 Turbidity Calibration The meter has been factory calibrated. For best accuracy and regulatory compliance, re-calibration is recommended at least once every month. In addition, it is recommended to use the prepared calibration standard vials daily as check standards prior to the measurement of samples.
  • Page 9 Also, do not store in freezing temperature will cause irreversible shrinkage of the standards particles thus resulting to inaccurate calibration and measurements. 5-1-2 Index Mark The United States Environmental Protection Agency (US EPA) recommends that vials used for turbidimeter calibration or sample measurement be indexed. Insert the calibration standard vial to the meter sample well so the diamond or orientation mark aligns with the raised orientation index mark in front of the sample well.
