Oxygen signal not responding
From Bioblast
Problems
- The oxygen signal remains at or close to zero even at high oxygen levels.
- The signal at air saturation is abnormally low.
Test and Solutions
The oxygen signal is very low at air saturation and less responsive than expected.
- Solution 1: Check the gain setting for the affected oxygen channel.
- The gain setting was too low, and the oxygen signal increases to the expected level after increasing the gain.
- The gain was correct: Locate the problem using the procedure described in Locating a problem and Sensor test.
