When all measurement cycles (1, 3 or 5) have been made, the average of the measurements is
shown on the display. Use the buttons at the cycle counter (D) to select the specific measures for
each cycle.
A further feature is the extraction of the U-values (E) from the suction/retraction curve. These
values may be used for a more comprehensive analysis of the curve as explained in:

The figure shows how the U-values are extracted from the elasticity measurement. The immediate
deformation or skin extensibility (Ue), delayed distension (Uv), final deformation (Uf), immediate retraction
(Ur), and total recovery (Ua) are indicated in the figure together with point 0 (start), a (time at maximum
elongation), and b (final elongation after returning to normal pressure). The Ue is the elongation 0.1 s after
point 0 while Ur is the change in elongation 0.1 s after point a. The total recovery (Ua) is the difference
between the elongation in point a and b.

Use Measurement Name (F) in case you want to name/label the measurement for future
reference. This name will be archived in the saved- or printed measurements.
The Clear Result button clears all measurements.

8.4 Maintenance

Except for keeping the probe clean there is no preventive maintenance associated with the use of
the elasticity probe. To clean the probe front, simply wipe it off using a dry cloth. Should more
thorough cleaning be necessary, a drop of isopropyl alcohol may be applied to the cloth to remove
residual glue.
CAUTION: Only use a dry cloth to clean the interior surfaces of the measurement chamber.
Probe cables are delicate. Do not apply any unnecessary force stretching the cable (e.g. do not
pull the probe off the skin by pulling the cable or similar).
