- Ddana11Sep 12, 2025
If W. BLOCKED appears on your Hach Measuring Instruments, check the measuring path and complete a wiper test.
What to do if W. BLOCKED appears on Hach NITRATAX plus sc?
If W. BLOCKED appears on your Hach Measuring Instruments, check the measuring path and complete a wiper test.
Why is the EM TOO HIGH in my Hach Measuring Instruments?
The EM may be too high in your Hach Measuring Instruments because of high turbidity, organic content, or nitrate concentration, which exceeds the measuring range. To resolve this, check the measurement in the laboratory.
What to do if CONC. TOO HIGH in Hach Measuring Instruments?
If the concentration is too high in your Hach Measuring Instruments, it is because the nitrate concentration is too high, exceeding the measuring range. Check the measurement in the laboratory to resolve this.
