Hand mode (the hand holding probe) cannot work well.
Cause 1
In case of the hand holding probe, it’s hard to meet
all measurement conditions without any clue or ex-
perience.
Remedy
It is not necessary to continue to take data in
until automatic freeze is reached. If measure-
ment is difficult, you can stop measurement
and print or save data.
Remedy
For stable measurement, have the patient lay
himself, which helps you hold the probe
stable and control the probe angle. It is also
recommended to take measurement in such
a manner as applying the probe weight
against the probe, which does not harm the
eye.
Remedy
Lightly touch your hand holding the probe to
the patient forehead or cheek to secure the
position and posture of your probe holding
hand.
