What to do if Hach Measuring Instruments show 'Over range!'?
If the Hach Measuring Instruments display 'Over range!', it means the concentration exceeds the upper limit of the current method. To resolve this, dilute the sample and repeat the reading.
What to do if Hach DR 1900 show 'Absorbance > 3.5!'?
If the Hach Measuring Instruments display 'Absorbance > 3.5!', it indicates that the measured absorbance is more than 3.5. Dilute the sample and repeat the reading to resolve this issue.
What to do if Hach DR 1900 display 'Under range!'?
If the Hach Measuring Instruments display 'Under range!', it means the concentration is less than the lower limit of the current method. Examine the sample to fix this.
What to do if Hach Measuring Instruments show 'Failed in sending data!'?
If the Hach Measuring Instruments display 'Failed in sending data!', ensure that the module is inserted and latched correctly.
What to do if Hach DR 1900 Measuring Instruments show 'Please attach the module!'?
If the Hach Measuring Instruments display 'Please attach the module!', it means the module is not found when data is sent. Insert a module to resolve this.
What to do if Hach DR 1900 Measuring Instruments show 'Initializing Failed!'?
If the Hach Measuring Instruments display 'Initializing Failed!', it means the instrument failed while initializing. Set the instrument to off and then to on.
