vPad-A1 OPERATORS MANUAL
4.7.3 Pressure Source and Manometer
The Pressure Source and Manometer (Pressure) feature can be used to verify the
pressure transducers in a NIBP monitor, or other pressure-measuring devices.
Pressure parameters are not active during setup. Access the feature setup page by
swiping right from the NIBP Simulation page (
Figure 76
) or swiping left from the
Over Pressure page (
Figure 88
), then press when ready.
4.7.3.1 Mode
The
Pressure module has three Modes of operation.
• Auto - Inflates and regulates system pressure
• Manual - Passively measures system pressure
• Step - Inflates pressure in regular steps until it reaches the target pressure
4.7.3.2 Maximum Pressure
The Maximum Pressure parameter refers to the highest target pressure for Auto and Step regulation.
It can be set from 10 to 400 mmHg, in 1 mmHg increments. Parameter controls are disabled in
Manual Mode, since users and/or the DUT are in control of system pressure.
4.7.3.3 Delay Time
The
Delay Time controls the pause duration between intermediate pressure
levels in Step Mode. It can be set from 1 to 600 seconds, in 1 second
intervals. Parameter controls are disabled in Auto and Manual Mode.
4.7.3.4 Pressure Step
The Pressure Step parameter sets the size of each intermediate pressure
interval in Step Mode. It can be set from 10 to 400 mmHg, in 1 mmHg
increments. Parameter controls are disabled in Auto and Manual Mode.
For example, in
Figure 83
, the setup page is in Step Mode. Once the test is
started, A1 will inflate system pressure from zero to the Maximum Pressure
of 100 mmHg. In the process it will pause for 5 seconds Delay Time at
every 20 mmHg Pressure Step.
