Section 3: Performance Verification
3- 11
These tests can be performed individually (in any order) or sequentially.
However, all of the tests must be performed to verify the pneumatic system
functionality. Prior to performing any of these tests, perform the following
setup procedure. If these tests are performed in sequence, this procedure
needs to be performed once prior to the first test.
1.
Turn on the Bio-Tek simulator and press the MODE button three times
to place the simulator in the tests mode. The simulator screen will
indicate “Internal Cuff” and “Pressure Gauge.”
2.
Connect the simulator hose to the hose connector on the right side panel
of the N-3100.
3.
With the N -3100 in the standby mode (off) and connected to AC power,
while simultaneously pressing and holding the UPPER ALARM LIMIT
button, the LOWER ALARM LIMIT button, and the PRINT button,
press and release the ON/STANDBY button. Continue to hold down the
UPPER ALARM LIMIT, LOWER ALARM LIMIT and PRINT buttons
until the Power-On Self-Test is complete. “SEr” will flash in the
MEAN/PULSE RATE display.
4.
Within 15 seconds, press and release the PRINT button to place the
N-3100 in the service mode steady state. “SEr” is continuously displayed
in the MEAN/PULSE RATE display.
Note:
To exit any test and return to the service mode steady state,
press the LOWER ALARM LIMIT button.
To exit the service mode steady state at any time, press the
ON/STANDBY button to turn the N-3100 off.
If there is no button activity for 5 minutes, the N -3100 will shut
itself off and exit the service mode.
3.3.2.1 Pressure Transducer Accuracy
Perform the following test to verify the pressure accuracy of the N-3100
pressure transducer. Prior to performing this procedure, the setup procedure
in paragraph 3.3.2, “Verification of Pneumatic System” must be completed.
1.
Press the UP/DOWN ARROW buttons until menu item 30 is displayed in
the SYSTOLIC display.
2.
Press the UPPER ALARM LIMIT button.
3.
Press the START/STOP button. The simulator begins to pressurize. The
current pressure in mmHg is displayed in the DIASTOLIC display.
4.
Allow 30 seconds for the pressure to stabilize.
5.
The numbers displayed by the simulator and in the DIASTOLIC display
should be within 4 mmHg of each other to successfully complete the test.
6.
Manually stop the test with the START/STOP button.
Note:
If the test is not stopped manually within 10 minutes, the
N-3100 will automatically stop the test.
7.
Return to the service mode steady state by pressing the LOWER ALARM
LIMIT button.
