Alignment and Measurement
MEMO
It is recommended that you do intraocular pressure measure- ments several times. Since the intraocular pressure varies by heart beats and tears, often it is not possible to obtain exact measurement values by measuring only once or twice.
The alignment operation can be performed with the control lever.
Moving the machine body by the control lever
•When the machine body needs to be moved slightly back and forth or right and left, move the control lever in each direction.
Operating the control lever (back and forth, right and left)
Never insert your fingers under the measuring head.
CAUTION ∗ Inform the patient of this, too.
Careless insertion of fingers may cause injury by pinching.
•To move the measuring head vertically, turn the control lever right for raising and left for lowering.
