Measure the other eye.
Slide the stage to the right side and measure the left eye.
1. Left eye selected
After both eyes are measured, pupil distance (PD) will be displayed on the monitor.
If stage is slid to the right eye again without pressing the [Print] button, the last measurement will
be displayed. And when measuring button is pressed, the new value will be added to them.
Safety information about infrared light radiation for measurement:
As light sources for measurement, this instrument adapted two type of infrared LED. It was chosen
to satisfy the amount of energy exiting from the instrument never exceed the limit value
recommended by the international standard ISO 15004. This condition is satisfied even when the
instrument is operating at maximum light intensity and maximum aperture. (Maximum intensity is
the highest brightness the instrument is capable of delivering, including the highest brightness
achievable if over voltage is provided).
Detailed radiation information at normal usage of this instrument is like bellows.

. Keratometry @ 770nm (LED type IWL-BR30F):
-
Output < 0.03 mW/cm²
(Group 1 limit≤20mW/cm² for unweighted corneal and lenticular infrared radiation
irradiance, EIR-CL @ wavelength of 770 to 2500nm, acc. To ISO15004-2:2007, 5.4.1.4)
2
. Refractometry @ 880nm (LED type HE8807SG):
-
Output < 0.15 mW/cm²
(Group 1 limit≤0.7mW/cm² for weighted retinal visible and infrared radiation thermal
hazard, EVIR-R @ wavelength of 380 to 1400nm, acc. To ISO15004-2:2007, 5.4.1.6 a)
Print.
Press the [Print] button. The selected data in the [Setup] mode will be printed. (See chapter VII - Other
modes > Setup mode > Keratometry).
Lift the printing paper from one side and give it a sharp tug to tear it off after printing is completed. Fill
the name of the examinee in the [Name] box if necessary.
