In Auto mode there is a valve open initially and while the test is idle so that pressure
equalizes to zero.
Place the monitor in the calibration or service mode. (See your NIBP Monitors Service
Manual for instructions on how to enter calibration or service mode.) Please check all
connections.
Press the <Start> key. The valve closes and the pump will run. During this time the
screen will indicate "Inflation In Progress".
After the pressure stabilizes at the target test value, the test will begin automatically. The
screen indicator changes to "Test In Progress". The starting pressure is captured and the
timer begins counting.
At the end of the preset time (60 seconds default) the screen indicates "Test Complete".
The final difference from the start pressure is locked in as the Leak Rate. The valve does
not automatically open, so the user can continue troubleshooting if more time is needed
by observing the manometer value. The user can release the pressure by pressing reset
once without losing the results.
Manual Leak Test
In Manual mode the title bar does not indicate a target start pressure.
Figure LT2 shows the Leak Test Manual mode.
The valve is closed immediately so that the user has total control of the pressure in the
system.
In manual mode pressure in the system must be greater than 10mmHg for <Start> to
trigger a timed measurement. The timer runs for the preset time indicated in the title
bar and the result is locked in at the end. The internal valve does not open, the user
must release the system pressure.
Pressing Reset while running a manual test will stop the timer and clear the current
result. If pressure is not released from the system, pressing <Start> will begin a new
test starting at the current system pressure.
Leak Test Configuration Menu
Three user configured test sets are permanently stored for reduced setup time on
repeated operations.
This provides the user with flexibility to choose the test conditions that suit their needs.
F1-F3 (Set1 through Set3) select the settings to use or configure.
Left / Right arrow keys select the parameter to adjust.
Up / Down arrow keys adjust the value of the highlighted parameter.
Target Pressure range is 50 – 300 mmHg
Test Time range is 20 – 120 seconds
Changes are saved immediately.
In manual mode the time of the current set will be used.
Target pressure has no meaning in manual mode.
OverP Test (Over Pressure)
This mode is used to verify operation of, and determine the pressure at which, a
monitor's over pressure safety functions. For this test, the system is inflated and the
AccuPulse Plus graphs the pressure. When the overpressure valve releases, the
AccuPulse reports the maximum pressure achieved to the user on the screen in a pop
up window.
Both manual and automatic modes are provided. Some NIBP monitors have auto-inflate
to self-test their Over Pressure protection, manual mode may be used when this is the
case. In auto mode the AccuPulse internal pump will provide the system inflation.
Fig. LT2
F1 (Toggle) will toggle display of the final result window, allowing the user to review the
plot.
F2 (Reset) will reset the Leak Test and clear any results.
F3 (Start) start the automatic Leak Test.
F4 (Auto) / F4 (Manual) toggles between automatic using the internal pump, or manual
mode using the inflation bulb.
The button label states the current mode, Auto is the default.
The Up/Down arrow buttons cause the pressure scale to shift between 200, 350 and 450
mmHg max.
If the system pressure should exceed 400mmHg the AccuPulse unit will release the
pressure to protect itself and any attached equipment. This status will be indicated as
"> 400mmHg"
If the test time exceeds 120 seconds the status will be indicated as "Time Out" and no
result will appear.
Auto Over Pressure

state for the OverP
Test Mode.
