PREFACE
Thank you!
Thank you very much for your investment in DEWETRON's unique data acquisition systems. These are top-quality
instruments which are designed to provide you years of reliable service. This guide has been prepared to help you
get the most from your investment, starting from the day you take it out of the box, and extending for years into the
future.
This guide includes important startup notes, as well as safety notes and information about keeping your DEWETRON
system in good working condition over time.
We strongly suggest that you read this entire manual, especially the safety and care sections, as well as to avoid
damaging your DEWETRON system.
What is PU[REC]?
PU[REC] stands for PURE RECORDING and is your portable and reliable data acquisition system for field tests,
troubleshooting and maintenance in various application areas. The 16 available analog input channels support +/- 10 V
directly and with the use of one (or more) of the nine available types of Modular Smart Interfaces (MSI) in front of the
analog input, you can acquire almost any signal. The option of adding quasi-static channel expansion modules to the
PU[REC] provides additional measurement inputs for voltage, current, temperature or resistance.

Calibration
Every instrument needs to be calibrated at regular intervals. The standard norm across nearly every industry is
annual calibration. Before your DEWETRON data acquisition system is delivered, it is calibrated at our DEWETRON
headquater. Each of this system is delivered with a certificate of compliance with our published specifications.
Detailed calibration reports from our calibration system are available for purchase with each order. We retain them
for at least one year, so calibration reports can be purchased for up to one year after your system was delivered.
Support
DEWETRON has a team of people ready to assist you if you have any questions or any technical difficulties regarding
the system. For any support please contact your local distributor first or DEWETRON directly.

SAFETY INSTRUCTIONS
Your safety is our primary concern! Please be safe!
> Use this system under the terms of the specifications only to avoid any possible danger. If the unit is used
in a manner not specified by the manufacturer the protection can be impaired!
> Ths product is intended for use in industrial locations. As a result, this product may cause interference
if used in residential areas. Such use must be avoided unless the user takes special measures to reduce
electromagnetic emissions to prevent interferences to the reception of radio and television broadcasts.
> Maintenance will be executed by qualified staff only.
> During the use of the system, it might be possible to access another parts of a more comprehensive
system. Please read and follow the safety instructions provided in the manuals of all other components
regarding warning and security advices for using the system.
> With this product, only use the power cable delivered or defined for the host country.
> DO NOT connect or disconnect sensors, probes or test leads, as these parts are connected to a voltage
supply unit.
> The system is grounded via a protective conductor in the power supply cord. To avoid electric shocks,
the protective conductor has to be connected with the ground of the power network. Before connecting the input
or output connectors of the system, make sure that there is a proper grounding to guarantee
potential free usage. For countries, in which there is no proper grounding, please refere to your local
legally safety regulations for safety use.
DC systems: Every DC system has a grounding connected to the chassis (yellow/green safety banana
plug).
> Please note the characteristics and indicators on the system to avoid fire or electric shocks. Before
connecting the system, please carefully read the corresponding specifications in the product manual.
> The inputs are not, unless otherwise noted (CATx identification), for connecting to the main circuits of
category II, III and IV. The measurement category can be adjusted depending on module configuration.
> The power cord separates the system from the power supply. Do not block the power cord, since it has to
be accessible for the users.
> Supply overvoltage category is II.
> DO NOT use the system if equipment covers or shields are removed.
> If you assume the system is damaged, get it examined by authorised personnel only.
> Any use in wet rooms, outdoors or in adverse environmental condition is not allowed!
Adverse environmental conditions are:
> Moisture or high humidity
> Dust, flammable gases, fumes or dissolver
> Thunderstorm or thunderstorm conditions (except assembly PNA)
> Electrostatic fields, et cetera.
> Any direct voltage output is protected with a fuse against short cut and reverse-polarity, but is NOT
galvanically isolated (except it is explicit marked on the system).
> The system must be connected and operated to an earthed wall socket at the AC mains power supply
only (except for DC systems).
> Any other use than described above may damage your system and is attended with dangers like shortcut,
fire or electric shocks.
