4-7-1 For Proper Measurement
▼ If the right/left eyes are not properly discriminated
● To ensure proper operation of the automatic right/left eye discrimination, note the
following:
•
When extending your hands between the patient's face and the main unit to
stabilize the main unit, do not touch the right/left eye sensors.
(See “2-1 Main Unit”)
•
Take measurement squarely in front of the patient's face as shown below. The
discrimination may fail if measurement is taken at an angle upward or sideways.
● If you follow the above main unit but the right/left eye discrimination still does not
work properly (for example, the measuring window is brought near the left eye, but
the right/left eye indicator remains “R”), switch to the manual right/left eye
discrimination.
The right/left eye discrimination can fail if:
•
The patient is wearing a mask.
•
The patient has a great deal of hair on either cheek.
•
The face is small, in the case of a child or baby.
