Symptom Solution
No output Check wiring. Ensure power supply meets
requirements.
Pressure reading error
Verify control panel software is configured for
correct output scaling.
Verify switch settings
Verify tubing is not pinched or leaking.
Possible contamination. Ensure sensor is used
only on dry air or nitrogen.
