5 Adjust the height of the chinrest, by operating the chinrest handle, so that the tail of
the patient's eye becomes level with the height mark of the chinrest post.
Setting the Safety Stopper
1 Hold the control lever and pull the machine body towards the operator.
2 Turn the control lever and adjust the height of the measuring nozzle to the center of
the patient's cornea.
3 While holding the safety stopper knob in a pressed position, hold the control lever
and slowly push out the machine body.
Before measuring, set the safety stopper. If the safety
stopper is not set, it may cause injury to the eye that
comes in contact with the measuring window glass. Set the
safety stopper separately for the right and left eyes.
When setting the safety stopper, do it from the instrument
side (safety stopper knob side).
Setting from another position does not easily allow you to
check the positions of the measuring window glass and the
patient's eye and may cause injury to the eye that comes
in contact with the measuring window glass.
