Introduction
XS Instruments, globally recognized as a leading brand in the field of electrochemical measurements, has
developed this new line of portable instruments completely produced in Italy, finding the perfect balance
between performance, attractive design and ease of use.
The robustness and integrity of the case, the integrated brightness sensor and the practical carrying case
make this instrument ideal for measurements directly in the field.
Thanks to the triple power supply and the ability to manually change the contrast and brightness of the
display, this instrument is also suitable for use in the laboratory.
The innovative high definition colour LCD display shows all the necessary information, such as the
measurement, the temperature, the buffers used for the last calibration (also custom), the condition of
stability.
Everyone can use these tools thanks to the instructions that appear directly on the display. The calibration
is guided step by step and the instrument configuration menu is easy to consult. In addition, a LED
indicates the status of the system to the user.
Up to 3 pH calibration points can be carried out between 8 automatically recognized values and 5 points
for Conductivity; in addition, buffers chosen by the operator can be used.
It is also possible to perform mV calibration for Redox sensors.
For an accurate measurement of the conductivity value, it is possible to work with 3 different cell
constants and to modify the compensation coefficient and the reference temperature.
It is possible to consult the calibration data anytime and the representation makes the calibration process
more efficient, through the icons of the buffers used.
The ideal solution for an accurate and precise measurement is to use an XS Sensor electrochemical
electrode with an XS Instruments device and perform the calibrations with XS Solution certified
calibration solutions.

2. Safety information
•Definition of warning words and symbols
This manual contains extremely important safety information, in order to avoid personal injury, damage to
the instrument, malfunctions or incorrect results due to failure to comply with them. Read entirely and
carefully this manual and be sure to familiarize with the tool before starting to work with it.
This manual must be kept near to the instrument, so that the operator can consult it easily, if necessary.
Safety provisions are indicated with warning terms or symbols.
•Reporting terms:
ATTENTION for a medium-risk hazardous situation, which could lead to serious injury or death, if
not avoided.
ATTENTION for a dangerous situation with reduced risk which can cause material damage, data loss
or minor or medium-sized accidents, if not avoided.

•Additional documents for safety
The following documents can provide the operator with additional information to work with the measuring
system safely:
•operating manual for electrochemical sensors;
•safety data sheets for buffer solutions and other maintenance solutions (e.g. storage);
•specific notes on product safety.
•Use according to destination
This instrument is designed exclusively for electrochemical measurements both in the laboratory and
directly in the field.
Pay attention to the technical specifications shown in the INSTRUMENT FEATURES / TECHNICAL DATA table;
any other use is to be considered unauthorized.
This instrument has been manufactured and tested in compliance with EN 61010-1 safety standards relating
to electronic instruments and has left the factory in perfect technical and safety conditions (see test report
in each package).
The regular functionality of the device and the operator safety are guaranteed only if all the normal
laboratory safety standards are respected and if all the specific safety measures described in this manual
are observed.
•Basic requirements for a safe use
The regular functionality of the device and the operator safety are guaranteed only if all the following
indications are respected:
•the instrument can be used in accordance with the specifications mentioned above only;
•use the supplied power supply only. If you need to replace the power supply, contact your local
distributor;
•the instrument must operate exclusively in the environmental conditions indicated in this manual;
no part of the instrument can be opened by the user.
Do this only if explicitly authorized by the manufacturer.
•Unauthorized use
The instrument must not run, if:
•it is visibly damaged (for example due to transportation);
it has been stored for a long period of time in adverse conditions (exposure to direct light, heat sources or
places saturated by gas or vapours) or in environments with conditions different from those mentioned in
this manual.
•Device maintenance
If used correctly and in a suitable environment, the instrument does not require maintenance procedures.
It is recommended to occasionally clean the instrument case with a damp cloth and a mild detergent. This
operation must be performed with the instrument off, disconnected from the power supply and by
authorized personnel only.
The housing is in ABS / PC (acrylonitrile butadiene styrene / polycarbonate). This material is sensitive to
some organic solvents, for example toluene, xylene and methyl ethyl ketone (MEK).

If liquids get into the housing, they could damage the instrument.
In case of prolonged non-use of the device, cover the BNC connectors with the special cap.
Do not open the instrument housing: it does not contain parts that can be maintained, repaired or replaced
by the user. In case of problems with the instrument, contact your local distributor.
It is recommended to use original spare parts only. Contact your local distributor for information. The use
of non-original spare parts can lead to malfunction or permanent damage to the instrument. Moreover, the
use of spare parts not guaranteed by the supplier can be dangerous for the user himself.
For the maintenance of the electrochemical sensors, refer to the documentation present in their packaging
or contact the supplier.
•Responsibility of the owner of the instrument
The person who owns and uses the tool or authorizes its use by other people is the owner of the tool and
is responsible for the safety of all users of the tool and third parties.
The owner of the instrument must inform users of the use of the same safely in their workplace and on the
management of potential risks, also providing the required protective devices.
When using chemicals or solvents, follow the manufacturer's safety data sheets.
