A square frame around the number means the pen, the eyelid or the eye moved, so take the reading again. Separate symbols show a pressure below 7 or above 50 mmHg.

Line the upper eyelid edge up with the upper edge of the cornea, place the rod 2 to 3 mm from the lid edge and lower the pen smoothly by 2 to 3 mm, keeping the buffer ring clear of the eyelid. A beep 1 to 2 seconds later means the reading is on the display; if there is no beep, or it comes after more than 3 seconds, measure again. Do not let the eyelid slip onto the cornea.
