Notes:
1. The
Counts column shows typical digital counts from the computer with the expected ( range ) shown in parenthesis.
2. The Actual column shows current values in real time with inputs in their baseline state.

Range Comments
Inspiratory Flow 2050
(1800-2300) 0.000 L/min -120 to 120 L/min Zero Offset Reading (nominal 2050 Counts)
Increased flow = more counts/more positive
Expiratory Flow 2050
(1800-2300) 0.000 L/min -120 to 120 L/min Zero Offset Reading (nominal 2050 Counts)
Increased flow = less counts/more negative
Airway Pressure 800
(550-1050) 0.000 cmH2O -20 to 120 cmH2O Zero Offset Reading (nominal 800 Counts)

Battery Voltage 3609 7.215 Volts 0 to 8.220 Volts > 8 Volts (10 sec) = Battery Failure High
< 5.65 Volts = Low Battery Voltage
< 2 Volts = Battery Failure Low
Battery Current 997 -0.008 Amps -2 to 6.190 Amps < -750 mA = Battery Charger Fail
-330 to -700 mA (1 min) = Battery charging
