Sensor problem 12 is commonly caused by a defective membrane or dried electrolyte. This video tutorial will guide you through the steps to resolve the error message.
|Possible Cause||Recommended Action|
|Membrane related (defective or dried up electrolyte)||Change the membrane:
1) if it is damaged or missing, has a loose fit, or if there is trapped air or dry electrolyte under the membrane
2) if the ‘Sensitivity Test’ fails.
|PCO2 electrode and/ or white PO2 sensing spot contaminated||If after having changed the sensor membrane the ‘Sensitivity Test’ still fails contact qualified service personnel to clean the sensor without membrane.|
|Sentec TC Sensor defective||If the problem persists the Sentec TC Sensor is defect. Replace it with a new one.|
