What to do if Respironics Measuring Instruments shows E03 error?
- MmmartinAug 17, 2025
If the Respironics Measuring Instruments displays 'E03' error, it could be due to the Disposable Tip being removed between calibration and measurement, or excessive ambient light. First, press and release F1 and F2 simultaneously. Then, remove the BiliCal, replace the tip, and recalibrate. If the error persists despite not removing the tip, the ambient light may be too high; move to a lower light environment and press F1 and F2 buttons together.
