Calibration Diagnostics and Calibration Procedure
WARNING: If there is an external mercury column connected, the test
may exceed the pressure rating of the mercury column.
b. Highlight the Overpressure Test Option and press the SELECT key to start the test.
When this option is selected the pump is started in an attempt to pump up to a
pressure of 395 mmHg. The test indicates the maximum pressure reached and
indicates whether the overpressure sensor was activated as shown in Figure 7-7.
c. Press the RECORD key to obtain a printout of the test results.
d.
Press the DEFLATE key and then the SELECT key to repeat the OVERPRESSURE TEST,
or press the DEFLATE key to quit the test and return to the NIBP Pneumatic Test Menu.
NOTE: Neonate overpressure test will occur in units with Rev TA
software only.
NOTE: The NIBP hose with a safety leak fitting cannot be used,
otherwise the test results are invalid.
7.5.1.2 Pulse Channel Test
The purpose of this test is to measure the DC offset and average noise in the pulse channel of
the NIBP module for each of the three possible gain settings. During the test the cuff
connector should be open.
a.
Highlight the Pulse Channel Test option from the NIBP DIAGNOSTICS menu and
press the SELECT key to start the test. The test results will be displayed as shown in
Figure 7-8.
b.
Press the RECORD key to obtain a printout of the test results
c.
Press the DEFLATE key and then the SELECT key to repeat the PULSE CHANNEL TEST,
or press the DEFLATE key to quit the test and return to the NIBP Pneumatic Test Menu.
7.5.1.3 Pressure Calibration
The purpose of this test is to adjust the sensitivity of the transducer circuit for optimal accuracy
and for checking the linearity at three separate pressure points.
