7.9 With the Run Compressor option still highlighted, press the
output will increase to level "10", indicated by the (10) on the LCD display, and the Output
Pressure shown on the LCD display should rise and then stabilize.
7.10 Compare the value of the Output Pressure on the LCD display with the value shown on the
external pressure meter:
7.10.1 If the value of the Output Pressure on the LCD display is within ±5 mmHg of the value
shown on the pressure meter, then continue with the test. Go to Para 7.11.
7.10.2 If the value of the Output Pressure on the LCD display is NOT within ±5 mmHg of the
value shown on the pressure meter, then do the following:
7.10.2.1
7.10.2.2
7.10.2.3
7.11 Repeat Para 7.9 and Para 7.10 six more times, for compressor output levels "15", "20", "25",
"30", "31" and "32". After the final check of the compressor output at level "32", continue the test
at Para 7.12.
Note: Levels 30, 31 and 32 are used to check that the compressor is at its maximum output,
and therefore the output pressure may not vary significantly between levels 30 and 32.
7.12 The calibration check of the pressure transducer is now complete, and the pump is able to
provide accurate therapy. To end the test, do either of the following:
7.12.1 With the Run Compressor option still highlighted, press the
compressor.
