5.2 FULL AUTO/AUTO Measurement
– 22 –
Start measurement
Tell the examinee that the mea-
surement is going to be per-
formed and ask the examinee to
open his/her eye wide.
Press
START
switch.
♦
How to stop auto alignment
Press any switch or turn the roller or trackball. The measurement head will stop.
However, if the measurement head is in a position where measurement can be
made, measurement will be performed if the
START
switch is pressed during auto-
matic alignment (compulsory measurement). Measurement error may occur, how-
ever, if the positioning is not accurate.
♦
When a warning message “[1] EYE CANNOT BE FOUND PRESS START
SW AGAIN” is displayed, or when alignment does not end
When automatic alignment cannot be performed within a specified time, the mea-
surement head stops moving and a warning message “
[1] EYE CANNOT BE
FOUND PRESS START SW AGAIN ” will be displayed. Also, in some cases, auto-
matic alignment does not end, due to the condition of examinee’s eye. In this case,
take the measures indicated below according to the cause.
[Cause 1]
The position of examinee’s eye is off the automatic alignment
range.
[Remedy 1]
Move the position of examinee’s eye displayed on the monitor
toward the center a little more using the roller and trackball. Then,
press the
START switch. Adjust the height of the examinee’s eye
with the height of the chin rest as required.
[Cause 2] Examinee’s eye is moving restlessly.
[Remedy 2]
Have him/her look at the eye fixation lamp. Or, if two bright dots
are displayed on the monitor, measurement will be performed if the
START switch is pressed timely during automatic alignment (com-
pulsory measurement).
NOTE: Measurement error may occur if the positioning is not
accurate. Perform compulsory measurement only when
measurement must be done even when the examinee’s eye
is not fixed.
