Calibration - Hoffrichter CPAP User Manual

CALIBRATION

Calibration guarantees an optimum performance of the automatic func-
tion and mask test. It must be performed when:
•
the device is used initially,
•
the mask has been changed,
•
there is a change within the therapy system. If a bacterial fi lter or a
humidifi er is added/removed the calibration has to be redone.
Ex factory, the point 2 is pre-calibrated for using with a Cirri Comfort nasal
mask (size M) without humidifi er and without bacterial fi lter.
Calibration is only possible during mains operation not in battery mode.
Calibrating the device
1. Connect the mask, the therapy tube and, if applicable, the humidifi er or
bacterial fi lter to the device.
Ensure that the air and exhalation openings in the mask are clear and
the tube is not kinked. Do not put the mask on.
