2) Make sure that the cursor is positioned at the
‘DPT_A’.
(Usually the cursor is at this position but if it is not,
move the cursor to the ‘DPT_A’ with ‘DOWN’ switch.)
3) Input the indicated value of the model eye in ‘DPT_A’ by pressing ‘+’ or ‘－’.
(Input ‘-0.100’ in case that the indicated value of the model eye is S: -0.1D.)
4) Align with the mode eye equivalent to 0D (align in
such a way that the Kerato ring becomes the thinnest)
and press the measurement start switch. After 10
times of continuous measurement, the values are
input in ‘AXS_A’, ‘CYL_A’ and ‘SPH_A’ automatically.
5） Press ‘Exit’ switch. The screen returns to the selection screen of ‘REF CALIBRATION’
and the calibration contents (values) are stored.
This is the end of calibration of the model eye equivalent to 0D.
When conducting calibration of the model eyes equivalent -10D, 10D and -5D, select
‘MODEL EYE B to F’ and follow the same procedures.
If the alignment moves during a measurement, the accuracy of the input
values is lowered. Prevent the alignment from moving during a measurement.
If turning off the power without pressing ‘Exit’, the contents of calibration
are not stored. Make sure to return to the ‘REF CALIBRATION’ screen.
