Cct 

Connected breathing circuit identification: 
  “S“ = Standard inspiratory heater connected 
  “C” = Coaxial inspiratory heater connected 
  “E” = Expiratory heater connected 
  “---” = No heaters detected while under heater wire control 
Non-Heater Wire Operation 
To enable non heater wire operation, press and hold both the mute and mode 
buttons simultaneously for 1 second.  The display will show ‘nhh’ and the humidifier 
will confirm with an audible beep.  Ensure that no heated breathing circuit is 
connected to the humidifier otherwise the humidifier won’t change operation. 
To disable non-heater wire mode, repeat the above process or connect a heater 
breathing circuit.   

CSP 

Chamber set point, in 0.1 °C resolution eg: 37.0 
Invasive mode: range 35.5 to 42 °C. 
Non-Invasive mode: range 31.0 to 36.0 °C. 

Cdc 

Chamber Duty Cycle (%) 
During selection of this menu and while a chamber probe out test is active the 
chamber probe indicator will light. 

CHP 

Chamber Power / Flow ratio (W/LPM) 

hP 

Heater Plate Temperature (1 °C) 

Flo 

Gas Flow Rate (0.1 LPM) 
  “---“ = Unknown Flow (flow measurement not started) 

FLr 

Gas Flow Rate Range: 
  “---“ = Unknown Flow (flow measurement not started) 
  “no” = No flow, ( Stand-by ) 
  “Lo” = Low flow, ( < 3 LPM ) 
  “In”  = Intermediate flow, ( 2 to 17 LPM ) 
  “Hi”  = High flow, ( > 13 LPM ) 
  “  -“  = Ventilated flow detected 

ASP 

Airway temperature set point (0.1

 

°C) 

Adc 

Airway Duty Cycle (%) 
During selection of this menu and while an airway probe out test is active the airway 
probe indicator will light. 

H2O 

Water out number, used to detect the presence of chamber water, calculated from, 
chamber power / (heater plate temp. – chamber temp.). 
During selection of this menu the water out indicator will light if the water out 
number falls below a dry chamber threshold.   

LAS 

Last Alarm State, the display will blank, and the humidifier’s last alarm will be shown 
on the indicators.  To clear LAS, press and hold the mute and mode buttons for 1 
second.  The humidifier will beep when LAS has been cleared. 

LFS 

Last Fault State, refer to section 6.3.  To clear LFS, press and hold the mute and 
mode buttons for 1 second.  The humidifier will beep when LFS has been cleared. 

SoF Software 

version 

End 

Press the mute button to cycle to the start of the menu, or the diagnostic menu will
