Practice Mode
When using the practice mode, the application operates in the
same manner as in the regular measurement mode described in
Chapter 8, "Patient SOS Measurement‚" page 8-1, except for
the following differences:
•
After the user carries out the second measurement, the
application calculates and provides the Coefficient of Vari-
ance (CV) value and measurement results by means of
a
score, according to a CV- score (precision-score) table (see
below). From that point on, following each new measure-
ment, the application provides the recalculated CV score.
•
The CV score is given per measurement site, and the CV
score is site dependent, accordingly.
CV score is a function of the Standard Deviation and your aver-
age measurements values. Your CV score should fall in the
range stated in the column labeled “Good”, in Table 14.1, for
each skeletal site before you start measuring patients.

•
The user can print the practice session results or data, but
these cannot be saved. If the
Save
button is pressed, a pop-
up dialog box opens, reading: “The Practice results/data
cannot be saved”.
