Service Manual Calibration 51
Noninvasive Blood Pressure calibration
1. Connect the cuff, digital pressure meter, bulb, and the Encore together with the cuff
calibration kit. Using T-connectors from the kit, connect the cuff, pressure meter, and
bulb.
2. Connect this NIBP test setup to the pressure transducer at PT1 on the Analog board.
3. Wrap the adult cuff around the black tube volume or a cylindrical object about the size
of an adult’s arm.
4. Press SETUP > MORE > MORE > SERVICE > YES > NIBP TEST > NIBP CAL. Use
the bulb to inflate the system pressure to 250 mmHg, as read on the pressure meter.
5. Watching the value of PR1 on the monitor screen, adjust RP2 until the service screen
reading matches the pressure meter.
6. Manually change the system pressure to check linearity tolerances at the following
levels:
7. Deflate the pressure to 0 mmHg.
8. Disconnect the tube from the transducer.
9. Set the oscilloscope to ac-coupled, bandwidth limited.
10. Connect the oscilloscope probe to TP47 on the Analog Board.
Note If testing takes more than 10 minutes, NIBP CAL will cancel. Press NIBP CAL
again and resume testing.
