7.2 ADJUSTING THE MEASUREMENT POSITION

WARNING!
Do not bring the tonometer into contact with the eye or push it into the eye (the tip of the
probe should be 4-8mm, or 5/32-5/16", from the eye).
Tonometer forehead and cheek supports with adjustment wheels.
To adjust the measurement position for your patient:
1. Adjust the supports using the adjustment wheels as shown in the above figure.
2. Keep the probe horizontal and pointing perpendicularly to the center of the cornea.
3. Set the distance between the tip of the probe and the center of the cornea to be
4-8mm (5/32-5/16") as shown in the below figure.
4. Read the distance setting (forehead A•1, A•2, etc.,
cheek B•1, B•2, etc.) between the arrows on the scale
(7) of the supports , see the figure left, and write it
down on a support position tag for the patient.

7.3 AUTOMATIC EYE RECOGNITION

NOTE!
Do not cover the eye recognition transmitters or sensor during the measurement, for example
with your fingers. Keep your hand, hair etc. and objects such as pillows away from the temple
side of your eye, as they produce an infrared reflection that causes an error.
The tonometer includes an automatic eye recognition system that identifies which
eye, right or left, you are measuring. The system has two infrared LED transmitters
just below the probe base and one infrared LED sensor above the probe base, as
in the figure below. The right-hand transmitter sends invisible infrared light to the
right and the left-hand transmitter to the left. The infrared light reflects from your
nose to the sensor. The sensor knows from which transmitter the reflected infrared
light came, and thus which eye you are measuring. The resulting eye indication is
included in the data that you can transfer to a PC, as described in the section 9.
