1 General description
1.1 Warnings and notes
Read before use
1.1.1 Safety warnings
In order to reach high level of operator safety while carrying out various measurements using
the EurotestXC instrument, as well as to keep the test equipment undamaged, it is necessary to
consider the following general warnings:
Read this Instruction manual carefully, otherwise the use of the instrument may
be dangerous for the operator, the instrument or for the equipment under test!
Consider warning markings on the instrument (see next chapter for more
information).
If the test equipment is used in a manner not specified in this Instruction manual,
the protection provided by the equipment could be impaired!
Do not use the instrument or any of the accessories if any damage is noticed!
Regularly check the instrument and accessories for correct functioning to avoid
hazard that could occur from misleading results.
Consider all generally known precautions in order to avoid risk of electric shock
while dealing with hazardous voltages!
Always check for the presence of dangerous voltage on PE test terminal of
installation by touching the TEST key on the instrument or by any other method
before starting single test and Auto Sequence® measurements. Make sure that
the TEST key is grounded thorough human body resistance without any insulated
material between (gloves, shoes, insulated floors, pens,...). PE test could
otherwise be impaired and results of a single test or Auto Sequence® can
mislead. Even detected dangerous voltage on PE test terminal cannot prevent
running of a single test or Auto Sequence®. All such behaviour is regarded as
misuse. Operator of the instrument must stop the activity immediately and
eliminate the fault/connection problem before proceeding with any activity!
Use only standard or optional test accessories supplied by your distributor!
In case a fuse has blown follow the instructions in this manual in order to replace
it! Use only fuses that are specified!
Service, calibration or adjustment of instruments and accessories is only allowed
to be carried out by a competent authorized person!
Do not use the instrument in AC supply systems with voltages higher than 550
Va.c.
Consider that protection category of some accessories is lower than of the
instrument. Test tips and Tip commander have removable caps. If they are
removed the protection falls to CAT II. Check markings on accessories!
cap off, 18 mm tip: CAT II up to 1000 V
cap on, 4 mm tip: CAT II 1000 V / CAT III 600 V / CAT IV 300 V

The instrument comes supplied with rechargeable Ni-MH battery cells. The cells
should only be replaced with the same type as defined on the battery
compartment label or as described in this manual. Do not use standard alkaline
battery cells while the power supply adapter is connected, otherwise they may
explode!
Hazardous voltages exist inside the instrument. Disconnect all test leads, remove
the power supply cable and switch off the instrument before removing battery
compartment cover.
Do not connect any voltage source on C1/C2 inputs. It is intended only for
connection of current clamps. Maximal input voltage is 3 V!
1.1.2 Markings on the instrument
Read the Instruction manual with special care to safety operation«. The
symbol requires an action!
Do not use the instrument in AC supply systems
with voltages higher than 550 Va.c.!
Mark on your equipment certifies that this equipment meets
requirements of all subjected EU regulations.
This equipment shall be recycled as electronic waste.
1.1.3 Warnings related to safety of batteries
When connected to an installation, the instruments battery compartment can contain
hazardous voltage inside! When replacing battery cells or before opening the
battery/fuse compartment cover, disconnect any measuring accessory connected to the
instrument and turn off the instrument,
Ensure that the battery cells are inserted correctly otherwise the instrument will not
operate and the batteries could be discharged.
Do not recharge alkaline battery cells!
Use only power supply adapter delivered from the manufacturer or distributor of the test
equipment!
1.1.4 Warnings related to safety of measurement functions
Insulation resistance
Insulation resistance measurement should only be performed on de-energized objects!
Do not touch the test object during the measurement or before it is fully discharged! Risk
of electric shock!
Continuity functions
Continuity measurements should only be performed on de-energized objects!

1.2 Testing potential on PE terminal
In certain instances, faults on the installation's PE wire or any other accessible metal bonding
parts can become exposed to live voltage. This is a very dangerous situation since the parts
connected to the earthing system are considered to be free of potential. In order to properly
check the installation against this fault the key should be used as an indicator prior to
performing live tests.
Examples for application of PE test terminal
Figure 1.1: Reversed L and PE conductors (plug commander)
Figure 1.2: Reversed L and PE conductors (application of 3-wire test lead)
Warning!
Reversed phase and protection conductors! The most dangerous situation!
If dangerous voltage is detected on the tested PE terminal, stop all measurements
immediately and ensure the cause of the fault is eliminated before proceeding
with any activity!

Test procedure
Connect test cable to the instrument.
Connect test leads to the object under test, see Figure 1.1 and Figure 1.2.
Touch test probe for at least 2 seconds.
If PE terminal is connected to phase voltage the warning message is displayed, display
is yellow coloured, instrument buzzer is activated and further measurements are
disabled in RCD tests, Rpe, Z loop, Zs rcd, Z auto, AUTO TT, AUTO TN, AUTO TN (rcd)
and Auto Sequences®.
Notes
PE test terminal is active in the RCD tests, Rpe, Z loop, Zs rcd, Z auto, Z line, ΔU,
Voltage, AUTO TT, AUTO TN, AUTO TN (rcd) measurements and Auto Sequences
only!
In case of detection of phase voltage on PE terminal in IT earthing system, the tests can
be enabled/disabled according to setting of parameter ‘Ignore PE warning (IT)’.
For correct testing of PE terminal, the key has to be touched for at least 2 seconds.
Make sure that the TEST key is grounded thorough human body resistance without any
insulated material between (gloves, shoes, insulated floors, pens, ...). PE test could
otherwise be impaired and results of a single test or Auto Sequence® can mislead. Even
detected dangerous voltage on PE test terminal cannot prevent running of a single test
or Auto Sequence®. All such behaviour is regarded as misuse. Operator of the
instrument must stop the activity immediately and eliminate the fault/connection problem
before proceeding with any activity!
