FOREWORD
The purpose of this manual is to provide the Customer with all possible information on the SKINFOLD CALIPERS, as well as the use and main-
tenance instructions to help maintain its performance and efciency over time.
The user manual must be kept in good condition and stored in a place where it is accessible for quick reference.
INTENDED USE
These skinfold calipers are used to measure in mm, with a measuring range between 0 and 40 mm (± 0.2mm) and a pressure of 10g/mm2 (± 10%),
the thickness of a skinfold with its substratum of body fat.
INSTRUCTIONS FOR USE
Before using the skinfold calipers, their operating pressure must be checked using the dynamometrical shell supplied, in the following way:
a) loosen the knob on the dial and adjust the dial so that the indicator is on 0, then retighten the knob (gure 1).
b) open the skinfold calipers and insert the dynamometrical shell from the elastic part between the two side plates of the skinfold calipers, keeping
the outer part of the shell strictly near the inner edge of the skinfold calipers (gure 1).
c) 2mm ± 0.2mm should be read on the dial; if this measurement does not correspond, adjust the Allen screw on the skinfold calipers spacer in
order to tighten the springs until 2mm ± 0.2 mm is read on the dial.
d) the skinfold calipers are ready for use.
NB: for correct use, it is recommended to repeat the operation daily.

HOW TO MEASURE SKINFOLDS
The skinfold calipers are applied on the skinfold after bringing the two edges of the skinfold close to the fat substrate to be measured
Fig. 2
1) To measure skinfolds, rmly grasp a skinfold between the tip of the thumb and index nger of your non-dominant hand and lift it. In this way,
the skin and the subcutaneous fat will be lifted and separated from the underlying muscles.
2) Hold the jaws of the skinfold calipers with your other hand and, after opening them by squeezing the handle, they will be released transversally
on the skinfold itself, right below (about 1 cm) the ngers that lifted it, so that the thickness can be measured. The values are read in millimetres directly on the graduated scale (dial) of the skinfold calipers right after the skinfold calipers have been released, in order not to cause a
progressive and excessive crushing of the soft parts
3) The value to be reported will be an arithmetic average of two successive measurements if the difference between them is not greater than 5%;
if the difference is greater, it is necessary to make a third accurate measurement and calculate the average between the latter and the closest
of the previous ones; in case of doubt, it is possible to carry out a greater number of counter-tests.
Sometimes, especially in women, it may be difcult to lift the skinfolds due to the fact that the subcutaneous tissue is often integral with the underlying muscle, to which it adheres rmly. In this case, it is advisable to pinch and release the skin fold several times before using the skinfold
calipers

SKINFOLDS TO BE MEASURED:
- Tricipital and subscapular in men (g.3)
- Tricipital and front thigh in women (g.4-5)
6
(g. 3)
Tricipital:
Vertical skinfold measured along the mediotricipital line halfway between the olecranon (elbow) and coracoid apophysis (shoulder).
Subscapular: Oblique skinfold at 45°, in the direction from the upper-medial to the lower-lateral, measured just below the tip of the scapula (shoulder).
(g. 4)
Tricipital:
Vertical skinfold measured along the mediotricipital line halfway between the olecranon (elbow) and coracoid apophysis (shoulder).
(g. 5)
Front thigh:
Vertical skinfold on the front midline of the thigh, halfway between the kneecap and the
upper margin of the iliac crest.
TABLE FOR ESTIMATING FAT PERCENTAGES IN MEN
1) Add up the thicknesses of the TRICIPITAL and SUBSCAPULAR skinfolds after measuring them with the skinfold calipers
2) In the column indicating the patient's age, slide down until you nd the value measured.
3) Using a ruler, move to the right towards the OBESITY and DIAGNOSIS columns and determine the values.

WARNINGS/MAINTENANCE
The SKINFOLD CALIPERS must be used by qualied personnel only.
Do not use the device if it is damaged. Do not repair it yourself; contact the manufacturer if necessary.
The skinfold calipers must be cleaned using a cloth dampened with substances that do not damage steel and it must always be stored in its case
in a dry place.
Cleaning agents can be, for example, alcohol or glass cleaner.
These SKINFOLD CALIPERS are designed to last: it is resistant to most chemicals, except for methyl ethyl ketones (M.E.K.), thinners and nail
polish removers.
