Preparing the calibrator
To prepare the Terumo CDI Model 540 Calibrator to perform a tonometered calibration
of the sensors, you need the CDI Model 540 Calibrator, one Terumo CDI Gas A bottle
(Model CDI506), and one Terumo CDI™ Gas B bottle (Model CDI507).
To install the gas bottles in preparation for calibration:
1 Connect the calibrator cable to the calibrator cable port on the back of the
CDI550 monitor by aligning the red dots.
2 Press the system mode and press the or keys until the calibrate mode
is highlighted. Press the √ key to enter the calibrate mode. Advance to the
screen where the gas bottle level indicators are shown.
3 Check the expiration date on the gas bottles. Each gas bottle has a shelf life
indicated by an expiration date printed on the bottle label.
4 Remove the caps from the calibration gas bottles.
5 Place the bottle of Gas A into the corresponding Gas A slot (orange sleeve)
on the calibrator, and turn the bottle clockwise until the gas bottle level indica-
tor on the “Calibrate” screen shows that the bottle has been engaged. After
engagement, give an additional one-half turn to the bottle.
6 Repeat step 4 with the bottle of Gas B into the corresponding Gas B slot (blue
sleeve) on the calibrator.
For the calibration procedure, you can hang the calibrator securely on the monitor
pole clamp arm (CDI Model CDI517 only), or rest it on a flat surface.
Warning
• Protect gas bottles from sunlight and do not expose to temperatures
exceeding 50°C (122°F). Do not pierce or burn, even after use. Do not
spray on a naked flame or any incandescent material.
