What to do if the signal is not in range and calibration value is very different from last calibration value on Hach Measuring Instruments?

  If the signal is not in range and the calibration value is very different from the last calibration value on Hach Measuring Instruments: * Open the sample flow adjustment valve completely. * Ensure the calibration gas doesn't have too much oxygen; use a quality 50 N2 or CO2 bottle. * Check for oxygen leaks between the reference bottle and instrument by increasing the gas flow rate and checking for a partial pressure (mbar) decrease.

  To address measurement spiking in Hach Measuring Instruments, ensure all tubing is tightly and correctly connected to the sample inlet and outlet connections. Additionally, remove any residual air bubbles from the sample line by turning the sample inlet/outlet valve to the PURGE position for 5 seconds.

What to do if stability is not reached and signal is not stable on Hach Orbisphere 3100?
- J
  John RobertsAug 23, 2025
  If the signal is not stable on Hach Measuring Instruments, wait for stability and check the reference gas or liquid flow rate. Also, check for the presence of liquid on the LDO membrane. If there is liquid in the flow meter, dry it by injecting 20 mL of ethanol (EtOH), then use N2 gas for 5 minutes.

  urobinsonSep 5, 2025
  If the signal is not stable and stability isn't reached, wait for stability and check the reference gas or liquid flow rate. Also, check for the presence of liquid on the LDO membrane, especially in the flow meter. If liquid is found, dry it by injecting 20 mL of EtOH followed by 5 minutes of N gas.

  If the signal is not in range and the calibration value is very different from the last calibration value, fully open the sample flow adjustment valve. Ensure that the calibration gas does not contain too much oxygen; use a quality 50 N or CO bottle. Check for oxygen leaks between the reference bottle and the instrument by increasing the gas flow rate and monitoring for a decrease in partial pressure (mbar).
