3.3.1 Checking of NIBP Calibration
The following section describes how to verify the NIBP calibration on a DINAMAP
™
Compact Vital Signs
Monitor. Refer also to the next section for details on re-calibration of a DINAMAP
™
Compact.
Checking of NIBP calibration is possible without disassembling the DINAMAP
™
Compact.
I. Set up the DINAMAP
™
Compact and calibration equipment as shown on page 38.
II. Switch on the DINAMAP
™
Compact and allow 10 seconds to settle.
III. Verify that the calibration pressure measurement system reads 0 mmHg (0 mBar)
IV. If the DINAMAP
™
Compact displays the language choice menu, choose “English”, then “OK”.
Reboot the DINAMAP
™
Compact by turning monitor off, and then back on.
V. Select the “Mode” button from the main menu. The Mode menu will be displayed
VI. Select the “Service” button from the mode menu
VII. Enter the Service Mode PIN code, 2 2 1 3. The Service menu will be displayed.
VIII. Select “NIBP” from the service menu. The NIBP Service menu will be displayed.
IX. Select “Check” from the NIBP service menu.
X. The DINAMAP
™
Compact now displays pressures on the systolic and diastolic displays.
XI. Check calibration of the DINAMAP
™
Compact unit is within specification at 0mmHg and
200mmHg (267mBar) applied pressure using a reference pressure measurement system.
Display Meaning Units System Range
Systolic Pressure measured at PT1
(main pressure transducer, on
Main Board)
mmHg 0-300
Diastolic Pressure measured at PT2 (on
pump assembly)
mmHg 0-330

Normal operation of the DINAMAP
™
Compact is not possible until powered off and back on.
