Barometric Pressure Check X1 = difference between the reference
pressure and the measured ambient
pressure displayed on the monitor
(-12 mmHg < X1 < +12 mmHg)
PCO

: P/X1/X2/X3/X4/X5/X6/X7
or
PCO

: F/X1/X2/X3/X4/X5/X6/X7
P = passed, F = failed
X1: xx (two digits)
X2: x.x
X3: x.x
X4: xxx
X5: x.x
X6: x.x
X7: x.x
Leakage Check parts 1 and 2 X2 = value of part 1 leakage check on
flowmeter (X2 </= 4.0 ml/min)
X3 = value of part 2 leakage check on
flowmeter (X3</= 4.0 ml/min)
Pump Check X4 > 120 mmHg below the ambient
pressure
Flow Rate Check X5 = CO
2
flow rate (42.5 ml/min <X5
<65 ml/min).

value and calculated value, based
on 5% CO

cal. gas (X7<2.6 mmHg,
or 0.35 kPa)
Calibration Verification X7 = difference between measured
CO

value and calculated value, based
on 10% CO
