Calibration Diagnostics and Calibration Procedure
1. Motor Pump Test
The purpose of this test is to determine if the output of the pump is adequate.
a. Connect the dummy cuff/test chamber to the side panel luer fitting.
NOTE: The dummy cuff/test chamber must be used for this test,
otherwise the test results are invalid.
b. Highlight the Motor Pump Test option and press the SELECT key to start the test. The
pump will start and inflate the chamber to 250 mmHg, then pressure is released.
During the inflation/deflation cycle the current pressure is displayed in the pressure
window. The time required to reach the target pressure will be displayed in units of
xx.x seconds as shown in Figure 7-4.

2.
Bleed Rate Test
The purpose of this test is to determine if the solenoids and orifices are performing properly.
a. Connect the dummy cuff/test chamber to the side panel luer fitting.
NOTE: The dummy cuff/test chamber must be used for this test,
otherwise the test results are invalid.
NOTE: The NIBP hose with a safety leak fitting cannot be used,
otherwise the test results are invalid.
b.
Highlight the Bleed Rate Test option and press the SELECT key to start the test.
Selecting this option causes the pump motor to inflate the test chamber to 170
mmHg. The largest orifice is then opened. The time required for the pressure to drop
from 150 mmHg to 130 mmHg is counted. The test is repeated for the middle and
smallest orifice. The chamber is then inflated to 250 mmHg. This time the dump valve
is opened and the time required for the pressure to drop from 250 mmHg to 20
mmHg is counted. The pressure is then released and the bleed rate for each orifice is
displayed in units of xx.x mmHg/sec. The current pressure is displayed in the
pressure window during the entire test. The format for displaying the test results is
shown in Figure 7-5.
