BASIC OPERATIONS
If the result is a figure in parentheses or ERR, do the measurement again, making
sure the patient does not blink and eyelashes do not get in the outer alignment mark.
If OVER is displayed, switch the measuring range to 0-60 and do the measurement
again.
Adjust the height of the automatic instrument table so that correct
measurement values can be obtained by allowing the patient to un-
dergo measurements in a comfortable position.
Make the patient relaxed so as to secure correct measurement val-
ues; make sure the patient does not hold his breath or remain tense.
