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 MultiServicerXD 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 use of the instrument may be
dangerous for the operator, for the instrument or for the equipment under test!
Consider warning markings on the instrument!
If the test equipment is used in manner not specified in this Instruction manual the
protection provided by the equipment may be impaired!
Do not use the instrument and 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!
All normal safety precautions have to be taken in order to avoid risk of electric
shock when working on electrical installations!
Use only standard or optional test accessories declared for this instrument and
supplied by your distributor!
Only test equipment provided or approved by Metrel should be connected to test
and communication connectors.
Only correctly earthed mains socket outlets shall be used to supply the
instrument!
In case a fuse has blown refer to chapter 10.2 Fuses to replace it!
Instrument servicing and calibration is allowed to be carried out only by a
competent authorized person!

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!
1.1.2 Warnings related to safety of measurement functions
1.1.2.1 HV AC, HV AC programmable
A dangerous voltage up to 5 kV a.c. is applied to the HV instrument outputs during
the test. Therefore special safety consideration must be taken when performing this
test!
Only a skilled person familiar with hazardous voltages can perform this
measurement!
DO NOT perform this test if any damage or abnormality (test leads, instrument) is
noted!
Never touch exposed probe tip, connections equipment under test or any other
energized part during the measurements. Make sure that NOBODY can contact them
either!
DO NOT touch any part of test probe in front of the barrier (keep your fingers behind
the finger guards on the probe) –possible danger of electric shock!
It is a good practice to use lowest possible trip-out current.
1.1.2.2 Differential leak., Ipe leak., Touch leak., Power, Leak’s &
Power
Load currents higher than 10 A can result in high temperatures of fuse holders! It is
advisable not to run tested devices with load currents above 10 A for more than 15
minutes. Recovery period for cooling is required before proceeding with tests!
Maximum intermittent duty cycle for measurements with load currents higher than 10
A is 50 %.
1.1.2.3 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!
1.1.2.4 Continuity functions (Rlow, Continuity)
Continuity measurement should only be performed on de-energized objects!

MI 3325 MultiServicerXD General description

1.1.3 Notes related to measurement functions
Insulation resistance (Riso)
If a voltage of higher than 30 V (AC or DC) is detected between TP1 test terminals, the
measurement will not be performed.
R low
If a voltage of higher than 10 V (AC or DC) is detected between TP1 test terminals, the
measurement will not be performed.
Parallel loops may influence on test results.
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 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.
Tests for sensitivity Idn(+) and Idn(-) are omitted for selective type RCD.
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 DC test current.
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 lowest 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
and Auto Sequences®.
Measuring Zref without test voltage present (disconnected test leads) will reset Zref
value to initial value.

MI 3325 MultiServicerXD General description
11
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.
Z line mΩ, Z loop mΩ
A 1143 Euro Z 290 A adapter is required for this measurements.
Z auto
See notes related to Zline, Zloop, Zs rcd and Voltage drop single tests.
Auto Sequences®
Auto Sequences® mode allows building custom-defined test sequences.
See notes related to single tests in the 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.
1.1.4 Markings on the instrument
Read the Instruction manual with special care to safety operation«. The
symbol requires an action!
Dangerous high voltage is present on terminals during the test. Consider
all precautions in order to avoid risk of electric shock.
Do not use in distribution systems with voltages higher
than 440 V.
Mark on your equipment certifies that it meets European Union
requirements for EMC, LVD, and ROHS regulations.
This equipment should be recycled as electronic waste.

1.2 Testing potential on TP1-PE terminal for installation tests
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. The instrument checks
the voltage between mains PE and PE terminal of TP1 connector.
Figure 1.1: Reversed L and PE conductors (application of 3-wire test lead)
Warnings!
Reversed line and PE conductors is the most dangerous situation!
If dangerous voltage is detected on TP1-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.
Test is automatically done after entering appropriate test function1)
If hazardous live voltage is detected between mains PE and PE terminal of TP1 connector and
three-phase rotary field is not detected, instrument displays warning icon , display is yellow
coloured, instrument buzzer is activated and further measurements are disabled: RCD tests,
Rpe, Z loop, Zs rcd, Z auto, Voltage drop ΔU and Auto Sequences®.
Notes:
1)The test on TP1-PE terminal is active in the Voltage, Rpe, RCD tests, Z loop, Zs rcd, Z
auto, Z line, ΔU and Auto Sequences only!
Make sure that the power supply socket for MI 3325 is properly grounded. PE test could
otherwise be impaired and results of a single test or Auto Sequence®can mislead.
1.3 Standards applied
