Why is the reading unstable during Crison Multimeter calibration?
To address unstable readings during calibration of your Crison Multimeter, ensure the probe is fully immersed in the sample. Inspect the probe, cleaning both it and the membrane, and verify there are no air bubbles present in the membrane. Then, repeat the calibration process.
What to do if Crison 44 Multimeter measurement is out of range?
If your Crison Multimeter displays a measurement out of range, examine the probe, clean it thoroughly, and inspect the cable for any damage. Replace the probe or cable if necessary.
How to fix 'worn out' electrode or contaminated buffer solutions on Crison 44?
If your Crison Multimeter's electrode is worn out or the buffer solutions are contaminated, examine the probe, clean or regenerate it, and replace if necessary. Also, examine the buffer solution, ensuring it matches the buffer specified in the configuration and that the temperature specification in configuration is correct. Replace the buffer solution if needed.
What to do if Crison 44 does not recognize buffer/standard solution?
If your Crison Multimeter displays a 'Buffer / Standard solution not recognized' message, examine the buffer solution. Ensure that the buffer used matches the buffer specified in the configuration. Replace the buffer solution. Also, ensure that the temperature specification in configuration is correct.
What to do if Cl measurement out of range on Crison Multimeter?
If the Cl measurement is out of range on your Crison Multimeter, verify the Cl sensor and clean it. Also, check the cable and replace it if necessary.
What to do if alarm relay is activated on Crison 44 Multimeter?
If the alarm relay is activated on your Crison Multimeter, verify the programmed limit value and the process evolution. After solving the problem, push the LEFT key for more than 3 seconds to restart the regulation.
Why is the alarm relay activated with sensor problems on Crison Multimeter?
If the alarm relay is activated with sensor problems on your Crison Multimeter, check the sensor and replace it if necessary. Verify any possible flow drop and the process evolution. Once the problem is solved, push the LEFT key for more than 3 seconds to restart the regulation.
How to troubleshoot DO channel probe sensor on Crison 44?
If you encounter a DO channel probe sensor issue with your Crison Multimeter, verify the DO sensor and replace it if necessary. Also, verify the cable and replace it if needed.
Why standard used in 2/3 point calibration is identical to precedent on Crison Multimeter?
To resolve the issue of the standard used in a 2 or 3 point calibration being identical to the precedent one on your Crison Multimeter, examine the buffer solution. Ensure that the buffer used matches the buffer specified in configuration, replace the buffer solution if needed and make sure of the temperature specification in configuration.
What to do if Crison Multimeter measured value is out of programmed limits?
If the measured value is out of the programmed limits on your Crison Multimeter, verify the programmed limit value and the process evolution.
