This application note provides instructions on how to calibrate the NIBP100A with AcqKnowledge software.
The NIBP100A is a noninvasive blood pressure monitor that uses a pressure sensor placed on the wrist over the radial
artery. This device uses a "sweep technique" which applies a varying force on the radial artery. The counter-pressure in
the artery produces a signal which is digitized and used to calculate blood pressure parameters. With just a few easy
calibration steps, the NIBP100A and an MP System with AcqKnowledge work together to provide automated, continuous,
noninvasive blood pressure measurements.
NOTE In normal conditions, the sensor should be at heart level; if the study requires that the arm is placed elsewhere,
adjust the sensor height on the NIBP100A to compensate for the difference by doing the following:
A. Press “setup” button on NIBP100A twice.

Screen should read SENSOR HEIGHT.
B. Press button on NIBP100A corresponding to ON.
C. Adjust the sensor height by pressing the touchpad below the SENSOR.

SENSOR  to raise sensor height.

SENSOR to lower sensor height.

USING DA100C
Hardware Setup
1. Connect the DA100C to the UIM100 module of the MP1XX.
2. Connect the TCI105 to the front of the DA100C.
3. Connect the NIA V-Line Interface to the TCI105 via phone jack.
4. Connect the parallel cable from the NIA V-Line Interface to the back of the NIBP100A at the "Data Port" location.
5. Set the Gain setting on the DA100C to 1000.
6. Connect the sensor to the back of the NIBP100A at the port marked "Patient Cable" and hang sensor properly on
cradle.
7. Turn the NIBP100A on via the switch on the back of unit.
8. Press Test when prompted.
o
This sensor test occurs each time the unit is powered on.
Software Setup for the MP1XX
1. Under the MP1XX menu select Setup Channels and enable one analog channel; make sure to correlate this with
the channel you selected on the top of the DA100 module.
2. Click the Scaling... button to generate the Change Scaling parameters dialog:
3. On the NIBP100A, push the "setup" button twice. The screen should be title SENSOR HEIGHT:
4. In the Scaling dialog, click Cal 1 and enter a Cal 1 Scale Value of 50.
5. On the NIBP100A, push the "setup" button twice. The screen should be titled SET CLOCK:
