Characterize NIBP
NIBP characterization sets the volume constants for the NIBP system to assure proper
cuff detection. You must characterize the NIBP system if any of the following occurs:
• Characterization test failure
• Pump failure
• Internal tubing replacement (any or all)
• Bleed valve, dump valve, or check valve replacement
• Main board replacement or repair
1. Attach a neonatal hose (008-0265-XX) to the monitor NIBP hose connector. Verify that
the hose length is 8 feet ± 4 inches (2.44 meters ± 10 cm).
2. On the monitor, navigate to the Characterize NIBP screen.

Note
Before beginning any service procedure, read the entire procedure to verify that
you have all tools and equipment needed and that you understand each step.
Caution Main board repair must be performed at the Welch Allyn Factory
Service Center. Any change to the main board requires system testing,
calibration, and verification, which can be done only at the Factory Service
Center.

equipped to perform the “Characterization test” on page 61. To complete this
test, you must have the 35-ml test syringe described in “35-ml test volume” on
