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!
Mark on your equipment certifies that it meets requirements of all
subjected EU regulations.
This equipment should 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!

MI 3152(H) EurotestXC (2,5 kV) General description

1.1.5 Notes related to measurement functions
Insulation resistance
The measuring range is decreased if using Plug commander.
If a voltage of higher than 30 V (AC or DC) is detected between test terminals, the
measurement will not be performed.
Diagnostic test
If any insulation resistance values (RISO(15 s) or RISO(60 s )) are over-ranged the DAR
factor is not calculated. The result field is blank: DAR:_____!
If any insulation resistance values (RISO(60 s) or RISO(10 min)) are over-ranged the PI
factor is not calculated. The result field is blank: PI :_____!
R low, Continuity
If a voltage of higher than 10 V (AC or DC) is detected between test terminals, the
measurement will not be performed.
Parallel loops may influence on test results.
Earth, Earth 2 clamp, Ro
If voltage between test terminals is higher than 10 V (Earth, Earth 2 clamps) or 30 V (Ro)
the measurement will not be performed.
Contactless earthing resistance measurement (using two current clamps) enables
simple testing of individual earthing rods in large earthing system. It is especially suitable
for use in urban areas because there is usually no possibility to place the test probes.
For two clamps earth resistance measurement clamps A 1018 and A 1019 should be
used. Clamps A 1391 are not supported. The distance between clamps should be at
least 30 cm.
For specific earth resistance measurements Adaptor A 1199 should be used.
RCD t, RCD I, RCD Uc, RCD Auto
Parameters set in one function are also kept for other RCD functions!
Selective (time-delayed) RCDs have delayed response characteristics. As the contact
voltage pre-test or other RCD tests influence the time delayed RCD it takes a certain
period to recover into normal state. Therefore a time delay of 30 s is inserted before
performing trip-out test by default.
Portable RCDs (PRCD, PRCD-K and PRCD-S) are tested as general (non-delayed)
RCDs. Trip-out times, trip-out currents and contact voltage limits are equal to limits of
general (non-delayed) RCDs.
The a.c. part of MI and EV RCDs is tested as general (non-delayed) RCDs.
The d.c part of MI and EV RCDs is tested with a d.c. test current. The Pass limit is
between 0.5 and 1.0 IdNDC.
The Zs rcd function takes longer to complete but offers much better accuracy of fault
loop resistance (in comparison to the RLsub-result in Contact voltage function).
Auto test is finished without x5 tests in case of testing the RCD types A, F, B and B+ with
rated residual currents of IdN = 300 mA, 500 mA, and 1000 mA or testing the RCD type
AC with rated residual current of IdN = 1000 mA . In this case Auto test result passes if all
other results pass, and indications for x5 are omitted.
Auto test is finished without x1 tests in case of testing the RCD types B and B+ with
rated residual currents of IdN = 1000 mA. In this case Auto test result passes if all other
results pass, and indications for x1 are omitted (MI 3152 only).
Tests for sensitivity Idn(+) and Idn(-) are omitted for selective type RCD.

MI 3152(H) EurotestXC (2,5 kV) General description
10
Trip out time measurement for B and B+ type RCDs in AUTO function is made with sine-
wave test current, while trip-out current measurement is made with d.c. test current (MI
3152 only).
Z loop, Zs rcd
The specified accuracy of tested parameters is valid only if the mains voltage is stable
during the measurement.
The measurement accuracy and immunity against noise are higher if I test parameter in
Zsrcd is set to ‘Standard’.
Fault loop impedance (Z loop) measurements will trip an RCD.
The Zs rcd measurement does not normally trip an RCD. However if a leakage current
from L to PE already flows or if a very sensitive RCD is installed (for example EV type)
the RCD could trip. In this case setting parameter I test to ‘Low’ can help.
Z line, Voltage drop
In case of measurement of ZLine-Line with the instrument test leads PE and N connected together
the instrument will display a warning of dangerous PE voltage. The measurement will be
performed anyway.
Specified accuracy of tested parameters is valid only if mains voltage is stable during the
measurement.
If the reference impedance is not set the value of ZREF is considered as 0.00 Ω.
The highest value of Zref, measured at different settings of the Test or Phase
parameters is used for Voltage drop (ΔU) measurement in Voltage drop single test,
Zauto single test, auto tests and Auto Sequences®.
Measuring Zref without test voltage present (disconnected test leads) will reset Zref
value to initial value.
Power, Harmonics, Currents
Consider polarity of current clamp (arrow on test clamp should be oriented toward
connected load), otherwise result will be negative!
Illumination
A 1172 and A 1173 illumination probes are supported by the instrument.
Artificial light sources reach full power of operation after a period of time (see technical
data for light sources) and should be therefore switched on for this period of time before
the measurements are taken.
For accurate measurement make sure that the milk glass bulb is lit without any shadows
cast by hand, body or other unwanted objects.
Refer to the Illuminance handbook -for more information.
Rpe
The specified accuracy of tested parameters is valid only if the mains voltage is stable
during the measurement.
Measurement will trip an RCD if the parameter RCD is set to ‘No’.
The measurement does not normally trip an RCD if the parameter RCD is set to ‘Yes’.
However, the RCD can trip if a leakage current from L to PE already flows.
IMD
It is recommended to disconnect all appliances from the tested supply to receive regular
test results. Any connected appliance will influence the insulation resistance threshold
test.

MI 3152(H) EurotestXC (2,5 kV) General description

Z line mΩ, Z loop mΩ
A 1143 Euro Z 290 A adapter is required for this measurements.
AutoTT, Auto TN(RCD), Auto TN, Auto IT, Z auto
Voltage drop (ΔU) measurement in each Auto test (except Z auto) is enabled only if ZREF
is set.
See notes related to Z line, Z loop, Zs rcd, Voltage drop, Rpe, IMD and ISFL single tests.
Auto Sequences®
Metrel Auto Sequences®are designed as guidance to tests in order to significantly
reduce testing time, improve work scope and increase traceability of the tests performed.
METREL assumes no responsibility for any Auto Sequence® by any means. It is the
user’s responsibility, to check adequacy for the purpose of use of the selected Auto
Sequence®. This includes type and number of tests, sequence flow, test parameters
and limits.
See notes related to single tests of selected Auto Sequence®.
Compensate test leads resistance before entering Auto Sequences®.
Zref value for Voltage drop test (ΔU) implemented in any Auto Sequence® should be set
in single test function.

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!

MI 3152(H) EurotestXC (2,5 kV) General description
13
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!

1.3 Battery and charging
The instrument uses six AA size alkaline or rechargeable Ni-MH battery cells. Nominal
operating time is declared for cells with nominal capacity of 2100 mAh. Battery condition is
always displayed in the upper right display part. In case the battery is too weak the instrument
will be turned off automatically.
The battery is charged whenever the power supply adapter is connected to the instrument.
Internal circuit controls charging and assures maximum battery lifetime.
Refer to chapters 3.2 Connector panel and 4.4.2 Battery indication for power socket polarity
and battery indication.
Notes
The charger in the instrument is a pack cell charger. This means that the battery cells
are connected in series during the charging. The battery cells have to be equivalent
(same charge condition, same type and age).
If the instrument is not to be used for a long period of time, remove all batteries from the
battery compartment.
Alkaline or rechargeable Ni-MH batteries (size AA) can be used. METREL recommends
only using rechargeable batteries with a capacity of 2100 mAh or above.
Unpredictable chemical processes can occur during the charging of battery cells that
have been left unused for a longer period (more than 6 months). In this case METREL
recommends repeating the charge/discharge cycle at least 2-4 times.
If no improvement is achieved after several charge / discharge cycles, then each battery
cell should be checked (by comparing battery voltages, testing them in a cell charger,
etc.). It is very likely that only some of the battery cells are deteriorated. One different
battery cell can cause an improper behaviour of the entire battery pack!
The effects described above should not be confused with the normal decrease of battery
capacity over time. Battery also loses some capacity when it is repeatedly charged /
discharged. This information is provided in the technical specification from battery
manufacturer.
