accuracy Check

Perform the following accuracy check monthly. Note that this procedure
is a check only. If you would like IOPI® Medical or an authorized electronics
shop to check the calibration rigorously, contact IOPI® Medical or your local
distributor for instructions.
NOTE: Practice this process a few times until the timing is smooth before
you record your readings. The exact starting and ending positions
are important.
1. Connect the Connecting Tube to the Pressure Port on the IOPI®.
2. Turn on the IOPI® and press the Peak button.
3. Set the front edge of the plunger of the syringe just touching the
back edge of the 30 ml mark (see Figure 1).
4. Leave the plunger in this position and connect the syringe tubing to
the metal end of the Connecting Tube.
5. Over a period of about 5 seconds, depress the plunger so that its front
edge ends up just touching the back edge of the 15 ml mark
(see Figure 2).
6. Note the peak pressure reading on the IOPI®.
7. Disconnect the syringe tubing from the Connecting Tube and push
the Reset button on the Peak function.
8. Repeat Steps 3–7 several times. Discard readings if you know you
pushed the plunger past the ideal position, or if the depression time
was too slow or too fast. If there is variability in the readings, this is
due to variability in your method. Repeat until your reading
stabilizes (±1 kPa).
9. Using the altitude at your location, compare this pressure reading
to Figure 3 (for altitude in meters) or Figure 4 (for altitude in feet).
10. If the pressure reading does not fall within the shaded region
of Figure 3 or 4, contact IOPI® Medical or your local distributor.
