FOREWORD
1. This manual is integral part of the shipment and it is supplied with the product even if not listed
in the invoice.
This manual can also be sent during purchase negotiations on Buyer’s request provided that the
Buyer states end application of the Product.
Except as expressly requested by the Buyer, only one copy of this manual may be attached to
shipments consisting of more than one unit of the Product.
Additional or updated copies of this document may be found on our web site at the following
address: www.dseurope.com
2. The products, which are the subjects of this manual, are designed and manufactured for general
use; therefore, being not possible to specify limits of use for all applications, the Buyer shall
introduce safety measures in order to avoid personal injuries, damages to property or damages
due to plants stoppage etc.
In case of use that can cause risk of damages, the Buyer shall immediately a notice the Supplier
in order that It can suggest safety solutions or can decide to reject the order and not deliver the
Product.
3. Series Pitagora instruments are not certified instruments; it is Buyer’s responsibility to check
instrument suitability to the requirements of the specific application.
4. Series Pitagora instruments, even when connected to transducers or other equipment, are only
parts of more complex systems and plants; they are sold in thousands pieces. Every year, for
most different applications which shall meet as many different norms that are not always known
to the Supplier.
For these reasons, DS Europe is obliged to disclaim all responsibility concerning the use of the
instrument; however, a list of most elementary and basic precautions for the correct use of the
instrument is given in this manual.
Besides, the need of a complete and specific insurance is highlighted, especially when systems
and machinery are to be installed in Countries like United States or Canada.
5. Series Pitagora instruments are designed and manufactured by DS Europe conforming to the
highest quality standards; the instruments are rugged and designed to the highest possible
safety and reliability: limitations and precautions listed in this manual are aimed to draw
Buyer’s attention to the importance of avoiding damage.
6. During manufacturing process, series Pitagora of instruments are submitted to several
intermediate tests and to a final test including performance test of all functions.
Electrical, temperature and mechanical sampling tests are periodically carried out to check
conformity of manufactured items to Product specifications.
For the above mentioned reasons, It is hereby certified that the delivered Product is
completely operating.
