Checking Accuracy
Accuracy of the monitor pressure readings should be checked annually. Recalibration is necessary only if the unit
is not within the accuracy limits.
Required Equipment
1. A full-size mercury sphygmomanometer or aneroid gauge.
• Ensure the mercury sphygmomanometer or aneroid gauge is calibrated and indicates "0" with
!
no pressure.
En
2. T-tube (P/N 016-0040-00).
3. A pressure cuff and a rigid cylinder sized to fit the pressure cuff.
Accuracy Procedure
To check the accuracy of the monitor:
1. Disconnect the cuff hose from the monitor. Connect the T-tube splitter to the monitor Luer-Lok connector and
the sphygmomanometer.
2. Wrap the pressure cuff around the rigid cylinder, and fasten the cuff. Connect the cuff hose to the remaining
connection on the T-tube splitter. The test setup should appear as shown below.
3. Press START/STOP on the monitor; the monitor should read approximately 165. Compare the readings on the
monitor and the manometer as the pressure bleeds down. The monitor reading should be within three
millimeters of the manometer reading or 2% of the reading, whichever is greater (+ the accuracy of the
manometer).
• If the monitor pressure values fall outside of the allowed tolerance call your local Customer
!
Service Representative or Spacelabs Medical for servicing.
4. At the end of the procedure, the monitor displays an event code indicating that no dynamic blood pressure
measurements were obtained.
