Introduction

XS Instruments, globally recognized as a leading brand in the field of electrochemical measurements, has

developed this new line of professional bench instruments, which is completely produced in Italy, finding

the perfect balance between performance, attractive design and ease of use.

The perfect balance between the high performance of the instrument, a modern and attractive design

and the user-friendliness make this series of instruments the ideal solution for electrochemical

measurements in 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 made 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 Conductivity, it is possible to work with 3 different cell constants and

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 using an XS Sensor electrochemical

electrode with an XS Instruments device and perform the calibrations with XS Solution certified

calibration solutions.

Safety information

Details of the words and symbols of warning

The safety information in this manual is very important to avoid personal injury, damage to the instrument,

malfunctions or incorrect results due to failure to comply with them. Read this manual carefully in its

entirety and make sure you familiarize yourself with the tool before putting it into operation and starting to

work with it.

This manual must be kept in the vicinity of the instrument, so that the operator can consult it 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, if not avoided, can cause material

damage, data loss or minor or medium-sized accidents.

ADVICE for important product informations.

NOTE for useful important informations.

Warning symbols:

Attention

This symbol indicates a potential risk and warns you to proceed with

caution.

Attention

The instrument must be used following the indications of the reference

manual. Read the instructions carefully.

Advice

This symbol draws attention to possible damage to the instrument or

instrumental parts.

Note

This symbol highlights further information and tips.

Attention

This symbol draws attention to a possible danger from electric current.

Rev. 1 20.12.2019

Additional documents that provide safety information

The following documents can provide the operator with additional information to work safely with the

measuring system:

operating manual for electrochemical sensors;

safety data sheets for buffer solutions and other maintenance solutions (ex 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 outside them is to be considered unauthorized.

This instrument has been manufactured and tested in compliance with EN 61010-1 safety standards for

electronic instruments and has left the factory in perfect technical conditions (see test report in each

package) and safety.

The regular functionality of the device and the operator’s 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 safe use

The regular functionality of the device and the operator's safety are guaranteed only if all the following

indications are respected:

the instrument can only be used in accordance with the specifications mentioned above;

if using the instrument with the power supply, use only the model supplied. 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;

the only part of the instrument that can be opened by the user is the battery compartment.

Carry out other operations only if explicitly authorized by the manufacturer.

Unauthorized use

The instrument must not be put into operation if:

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 with 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 procedure.

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 and disconnected from the power supply and only by

expert and authorized personnel.

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).

Rev. 1 20.12.2019

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 only original spare parts. 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

as such 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.
