not give accurate results during normal operation.
Note: Do not use ZERO CAL with Hach reagents. The reagent blank value of Hach reagents (molybdate) is
measured during controlled conditions at the factory and is very accurate. To enter the reagent blank value for
Hach reagents, use the OVERRIDE CALIBRATION option (refer to
