6.4.7.4 Leak Test (250mmHg, 150mmHg, 50mmHg)
The purpose of the leak test is to verify the leak rate of the pneumatic components.
1. Connect the dummy cuff / test chamber to the side panel fitting.
2. Rotate the control knob to highlight the leak test. Once the leak test is highlighted press
the control knob to activate the test.
3. The chamber will inflated to 250, 150 or 50 mmHg of pressure. After ten seconds the
pressure on screen the pressure is released. During this ten second period the monitor
will determine the leak rate and display the total drop in pressure for that period.
