is
performance and efficiency. The operating instructions manual should be kept in good state and be
easily accessible for quick consultation. The skinfold caliber is subject to up-datings and therefore
different items may be assembled to it than those depicted. This possibility does not prejudice in any

USE
The skinfold caliber may be used by professional medical staff and as such it is marked with the CE
0476
certificate, which denotes a class I medical device that has the function of measuring in accordance
with CEE directive 93/42.
PURPOSE OF THE DEVICE
The skinfold caliber is an instrument that has the function to measure in mm with a pressure of 10gr/
mm
2
(±
10
%) the thickness of a layer of skin tissue with its substratum of body fat.
INSTRUCTIONS OF THE DEVICE
Before using the skinfold caliber the calibration of the exercised pressure by its vice needs to be
verified with the supplied dynamometrical shell, proceeding in the following manner:
a)
Loosen the knob
(see fig. 5-12 )
on the quadrant and regulate the quadrant in the way that
the indicator is positioned on 0. After this tighten the knob again.
b)
Open the vice of the skinfold caliber and interpose the dynamometrical shell (see fig. 5-
(
11
) ,
pag.17
) on its elastic part between the two cheeks of the skinfold caliber, keeping the outer part of the
shell strictly nearby the inner side of the skinfold calibersí vice (see fig. 5
,
).
c)
On the quadrant it should read 2 mm +/- 0,2 mm. If this measure doesnít appear you should
regulate the allen screw (see fig. 5-13
,
) that is positioned on the spacer (fig. 5-3) of the skinfold
caliber, so that the springs are tightened until the measure of 2+/-0,2mm can be read on the
instruments quadrant.
d)
The skinfold caliber is ready for use.
N.B. for a correct use we suggest repeating the above operation every day.
HOW TO VALUE THE LAYERS OF SKIN TISSUE (fig. 1)
The skinfold caliber is applied on the layer of skin tissue after that you have drawn up the two ends of
the skin layer with its substrata of fat that has to be measured.
fig. 1
1) To value the layers of skin tissue, firmly grasp a layer of skin between the tip of the thumb and the
tip of the forefinger of your non-dominant hand and lift it. In this way the skin and the fat underneath
will be lifted and separated from the underlying muscular layers.
