8.10 To start the test, scroll down the list of options to Run Compressor, and select it using the
button. The compressor will start running at output level "5", indicated by the (5) on the LCD
display, and the Output Pressure shown on the LCD display should rise and then stabilize
(Refer to Figure 27).
8.11 With the Run Compressor option still highlighted, press the
compressor output will increase to level "30", indicated by the (30) on the LCD display, and the
Output Pressure shown on the LCD display should rise and then stabilize.
8.12 Compare the value of the Output Pressure on the LCD display with the value shown on the
external pressure meter:
8.12.1 If the value of the Output Pressure on the LCD display is within ±2 mmHg of the value
shown on the pressure meter, then:
8.12.1.1
8.12.1.2
8.12.2 If the value of the Output Pressure on the LCD display is NOT within ±2 mmHg of the
value shown on the pressure meter, then adjust the gain calibration factor of the pump
as follows:
8.12.2.1
8.12.2.2
8.12.2.3
8.12.2.4
8.12.2.5
8.12.2.6
8.13 Run the test to check the calibration of the pressure transducer (Refer to Page 7, Section 7).
