Calibration
Zeroing recommended when changing Airway adapter. No
span calibration required for the IR bench.
Room air calibration of oxygen sensor performed
automatically when changing airway adapter (<5s)
Warm up time
Concentrations are reported and the automatic agent
identification is running within 10s. Full accuracy within 20s
for IRMA AX+.
