Mode Of Use; Caution - PASI Polares 32 User Manual

3. Mode of use

Caution

The electrical imaging system for tomography POLARES 32 is a very sophisticated
instrument, but at the same time quite simple to use.
It should be remembered that the instrument uses potentially lethal electrical voltages and
currents; this means that the POLARES 32 instrument must be used by specially trained
personnel who have the necessary knowledge of the theoretical principles and methods
of measuring electrical resistivity in the soil, whether by quadripole or multi-electrode
tomographic methods.
In order not to leave room for improvisation, before using the instrument in the field it is
strongly recommended to read this manual carefully and to be familiar with the theory
(electrical engineering and geophysics) relating to the principles underlying the
methodology.
Before proceeding with field measurements, please do not hesitate to contact PASI
technical support to clarify any doubts.
Always bear in mind that there are physical limits to the application of the method, once
these limits are exceeded (resistivity too high or too low) the measurement is not possible,
even if the instrument is fully operational.
The instrument is protected - to the maximum of current technical possibilities - against
all foreseeable incorrect operations (indicated as such by the instrument itself); however,
the execution of incorrect operations may lead to damage to the instrument or danger to
the operator.
In these cases, only PASI's authorised technical support will decide whether or not the
fault falls within the scope of the warranty provided with the instrument. Any sending of
damaged or malfunctioning instruments to our laboratories must always be authorised in
advance by PASI technical support and must be performed according to the instructions
that will be communicated by PASI when necessary.
