Functional verification and calibration must be performed each time the device is disassembled or
more frequently if your facilty's procedures require a full calibration on a specified basis. If you have
just replaced a Main PCA board, your first step before performing a full verification and calibration is
to initialize the NIBP Board.
1. Set up the equipment for full functional verification as shown earlier in this section.
2. Log in to the Welch Allyn Service Tool, highlight your device in the Device list, and click
Select.
This action opens the

subtab. Depending on your
configuration, it could take 30-45 seconds to populate this subtab.

Verify and calibrate
subtab.
