What to do if the Hach Measuring Instruments reading flashes?
- Z
  Zachary GilesJul 27, 2025
  If the reading is less than the instrument range, ensure the instrument cap is fully installed over the cell holder. Measure a blank; if it's not zero, set the instrument to zero again. Alternatively, light blockage in the cell holder may be the issue; check for and remove any blockage. Dilute the sample and re-run the test. For factory-calibrated programs, note that maximum and minimum values cannot be changed.

Why does my Hach POCKET COLORIMETER II show E-1 error?
- G

How to fix E-6 error on Hach POCKET COLORIMETER II Measuring Instruments?
- L
  Lauren BanksAug 11, 2025
  The E-6 error appears when the absorbance value is incorrect, or the user-entered calibration curve has fewer than two points. Enter or measure the absorbance value again to fix this.

What to do if Hach Measuring Instruments shows E-7 error?
- M
  Molly KeithAug 16, 2025
  The E-7 error indicates the standard solution concentration matches another already in the user-entered calibration curve. Enter the correct standard concentration to resolve this.

How to resolve E-0 error on Hach POCKET COLORIMETER II Measuring Instruments?
- D
  Donald MeyersAug 21, 2025
  The E-0 error occurs in user calibration mode when a standard solution was measured before setting the instrument zero. To fix this, measure a blank solution to set the instrument to zero.
