4b Tests and Calibration 1.X/3.X Software
4b-16 05/04 1006-0453-000
Notes:
1. These columns show the acceptable range where possible.
2. The A/D count and displayed value shown for Airway Pressure, Manifold Pressure, Inspiratory Flow, and Expiratory Flow are the zero
pressure values. These readings should be taken with the flow sensors disconnected by removing the circuit module.
3. The count range and displayed value shown for GIV Current Sense is with the GIV turned on. If the GIV is turned off, the off count range
is 0 to 259 Counts.

Battery Voltage 1740-3976 7 to 16 Volts 0 to 16.48 Volts <7V = Low battery voltage failure.
<11.65V = Low battery voltage warning.
>16 Volts (10 Sec) = High battery voltage
failure.
Battery Current 700-4000 -600 mA to 6 Amps -2 to 6.19 Amps -150 to -600 mA = Battery charging.
-601 mA to -2 Amps = Charge current out of
range.
>300 mA = Operating on battery.
