The "Range" setting might be too low if the straylight value of the patient is much
increased.
In this case, there are too many 0 responses and not enough 1 responses
(Example 5).
In both cases, repeating the measurement with the same "Range" setting will not
yield a lower esd value.
You can only improve reliability by choosing a different "Range" setting.

Note
It is not always clear if the chosen range was too low (Example 6). In such a case it is
anyway a good idea to choose a higher "Range" setting, because the test will be easier to
perform then.
(Example 7) shows that the patient from Example 6 is perfectly able to do the mea-
surement. The chosen range in Example 6 was apparently too low.
