Pressing the Deflate key at any time during the test causes the NIBP module to open all valves and ends the test. Pressing and holding the Deflate key for three seconds clears the MAP display and exits test. The Cufflink simulator must be exited separately. NOTE: The reading and setting accuracy will be dependent on the accuracy of the Cufflink calibration and the Accutorr Plus condition. The Cufflink standard dynamic pressure simulation may produce Systolic / Mean / Diastolic read outs on the Accutorr Plus outside of the specified limits. The pressure simulation results may not be accepted as a measure of the Accutorr Plus clinical performance. 7.5.14 Over Pressure Transducer Verification (12c, 12a, 12b) This test verifies that the over-pressure transducer is calibrated correctly. Calibration is checked in the Low level pressure mode so that the limit displayed in the MAP window should say 158 mmHg (±1). If it does not, the transducer needs to calibrated by proceeding to 7.5.16 Over-pressure Transducer Calibration. The over-pressure transducer should also be verified in the High and Mid level pressure modes. 1. Select diagnostic test “12” (Room) “a” (Bed). Low Limit 2. Press the Start NIBP key to start the test. 3. Verify that the over-pressure value displayed in the MAP LEDs is 158 mmHg (±1). 4. Repeat steps 1 through 3, but select test “12” “c” to check over-pressure limit, 315 mmHg (±15); and test “12” “b” for Mid level over-pressure limit, 210 mmHg (±10). 5. Press the Deflate key to exit this test. 7.5.15 Main Pressure Transducer Calibration NOTE: This procedure should only be performed in the event that there was a failure in 7.5.12 Main Pressure Transducer Verification. This is the procedure for calibrating the main pressure transducer in the event that there is a disagreement between the UUT and the external pressure gauge in the proceeding test. The device is calibrated by comparison with the Cufflink simulator at 158 mmHg (±1) and then by adjusting R40 on the 0670-00-0584-01 PCB. 1. Connect the Cufflink simulator to the Accutorr Plus cuff connector, and connect a 700 cc test chamber to the open port of the simulator. Select the manometer function of the simulator. 2. Select diagnostic test “11” (Room) “d” (Bed). 3. Press the Start NIBP Key to start HIGH calibration procedure. 7-12 Revised 9/20/07 Accutorr Plus Service Manual Chapter 7 - Calibration
4. Pump up the Cufflink simulator to 158 ±1mmHg. 5. Allow pressure to stabilize for 10 seconds. Read the pressure in the MAP display. 6. Adjust R40 on the 0670-00-0584-01 PCB until the MAP readout is the same as the simulator’s manometer reading. 7. Press the Deflate key to exit this test. 8. Repeat 7.5.12 Main Pressure Transducer Verification. 7.5.16 Over Pressure Transducer Calibration NOTE: This procedure should only be performed if a failure occurred in steps 1 through 3 of 7.5.14 Over-Pressure Transducer Verification. This is the procedure for calibrating the over-pressure transducer in the event that the display does not read 158 mmHg during the test for Low pressure mode in 7.5.14 Over Pressure Transducer Verification. The transducer is calibrated using R4,on the 0670-00-0584-01 PCB. 1. Adjust R4, on the 0670-00-0584-01 PCB until MAP read out is 158 mmHg. 2. Repeat 7.5.14 Over Pressure Transducer Verification. 7.5.17 Battery Selection (13) This section will allow the user to configure the unit for a Sealed Lead Acid or Lithium Ion battery. 1. Select diagnostic test (Room) “13”. 2. Press the Start NIBP to enable the selection process. The pump will NOT start up. 3. The Diastolic display will show the currently configured battery type. Sealed Lead Acid will be represented by “La” and Lithium Ion will be represented by “Li”. 4. Using the Patient Info Up/Down arrow keys, select the appropriate battery type. 5. Press the Deflate key to confirm your choice. If the Deflate key is not pressed, the change will not take effect. Accutorr Plus Service Manual Revised 9/20/07 7-13 Chapter 7 - Calibration
