Display after measurements
Before
00
After the sixth measurement, the letter P appears on the display, followed by the IOP (Intraocular
pressure) reading.
If the P is blinking, it means that the standard deviation of the measurements is greater than normal.
P_ (line down) The standard deviation of the different measurements has a slightly greater value than
normally, but the effect on the result is unlikely to be relevant.
P _ (line in the middle) The standard deviation of the different measurements is clearly greater than
normal, but the effect on the result is probably irrelevant. A new measurement is recommended if the
IOP is over 19 mmHg.
_
P
(line up) The standard deviation of the different measurements is great and a new measurement is
recommended.
