Human NIBP Nano
Owner’s Guide
To perform a pressure check:
1. Ensure the Wrist Unit is connected to the Human NIBP Nano
Interface as described in Connecting the Wrist Unit on page 16.
2. Connect a finger cuff to C1 of the Wrist Unit by its cuff connector but
do not attach
the air outlet connector.
3. Connect a calibrated precision manometer to air outlet C1 of the
Wrist Unit (see Figure 2–23).
4. Launch LabChart and open the Human NIBP Settings dialog (
Setup
> NIBP Settings...
).
5. Next, select
Test mode...
and choose the
Steady pressure
option,
in which the generated pressure wave fluctuates around the
baseline pressure by a fixed off set of ± 50 mmHg (see Figure 2–19
on page 34).
6. Click
Start
in LabChart, and the click
Sample
in the Warning dialog
that appears. It will take around 20 seconds for the Human NIBP
Nano Interface to settle into the chosen
Steady pressure
level.
7. Click
Stop
to stop sampling and reopen the Human NIBP Test Mode
dialog to select a diff erent pressure level.
8. At each pressure level the precision manometer reading should be
within 3 mmHg (1% full scale) of the selected pressure level.
9. If the indicated pressures are not within tolerance, contact your
local ADInstruments representative to check the device.
Note:
There is no need to open the instrument for inspection or
maintenance, and doing so within the warranty period will void the
warranty.
