Why does Dräger Test Equipment say 'Not Allowed'?
- KKayla WhitakerSep 12, 2025
If your Dräger Test Equipment displays 'Not Allowed', it indicates that the breath sample delivery occurred at a not permitted time, meaning the instrument wasn't ready for measurement (reblow). Instruct the person being tested on the correct delivery of the breath sample, then start a new measurement.
