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 Zs rcd function takes longer to complete but offers much better accuracy of fault
loop resistance (in comparison to the RL sub-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.
 Trip out time measurement for B and B+ type RCDs in AUTO function is made with sinewave test current, while trip-out current measurement is made with DC test current (MI
3152 only).

General description
Z loop, Zs rcd
 The specified accuracy of tested parameters is valid only if the mains voltage is stable
during the measurement.
 Fault loop impedance (Z loop) measurements will trip an RCD.
 The Zs rcd measurement does not normally trip an RCD. However, the RCD can trip if a
leakage current from L to PE already flows.
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.
Power, Harmonics, Currents
 Consider polarity of current clamp (arrow on test clamp should be oriented toward
connected load), otherwise result will be negative!
Illumination
 LUXmeter type B and LUXmeter type C 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



IMD

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.
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.
Z line mΩ, Z loop mΩ
 A 1143 Euro Z 290 A adapter is required for this measurements.
Auto Tests
 Voltage drop (dU) measurement in each Auto test sequence is enabled only if Z REF is
set.
 See other notes related to single tests / measurements of selected Auto test sequence.

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
performing live tests.
key should be used as an indicator prior to
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
11
MI 3152(H) EurotestXC (2,5 kV)
General description



If PE terminal is connected to phase voltage the warning message is displayed,
instrument buzzer is activated and further measurements are disabled in Z loop, Zs rcd,
RCD tests and Auto test sequences.
Notes
 PE test terminal is active in the RCD tests, Z loop, Zs rcd, Z line, dU and Voltage
measurements and Auto test sequences only!


For correct testing of PE terminal, the
key has to be touched for at least 2 seconds.
Make sure to stand on non-isolated floor while carrying out the test, otherwise test result
may be wrong!

General description
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.

The works with MI 3152(H) EurotestXC can be organized and structured with help of
Workspaces and Exports. Exports and Workspaces contain all relevant data (measurements,
parameters, limits, structure objects) of an individual work.
Workspaces are stored on internal data memory on directory WORKSPACES, while Exports are
stored on directory EXPORTS. Export files can be read by Metrel applications that run on other
devices. Exports are suitable for making backups of important works. To work on the instrument
an Export should be imported first from the list of Exports and converted to a Workspace. To be
stored as Export data a Workspace should be exported first from the list of Workspaces and
converted to an Export.

Communication
9 Communication
Tree structure and stored results from Memory Organizer can be transferred to a PC. A special
communication program on the PC automatically identifies the instrument and enables data
transfer between the instrument and the PC.
There are three communication interfaces available on the instrument: USB, RS 232 and
Bluetooth.
9.1 USB and RS232 communication
The instrument automatically selects the communication mode according to detected interface.
USB interface has priority.
Figure 9.1: Interface connection for data transfer over PC COM port
How to establish an USB or RS-232 link:






RS-232 communication: connect a PC COM port to the instrument PS/2 connector
using the PS/2 - RS232 serial communication cable;
USB communication: connect a PC USB port to the instrument USB connector using
the USB interface cable.
Switch on the PC and the instrument.
Run the Metrel ES Manager software.
The PC and the instrument will automatically recognize each other.
The instrument is prepared to communicate with the PC.
Metrel ES Manager is a PC software running on Windows Vista, Windows 7, Windows 8 and
Windows 8.1.
9.2 Bluetooth communication
The internal Bluetooth module enables easy communication via Bluetooth with PC and Android
devices.
How to configure a Bluetooth link between instrument and PC



Switch On the instrument.
On PC configure a Standard Serial Port to enable communication over Bluetooth link
between instrument and PC. Usually no code for pairing the devices is needed.
Run the Metrel ES Manager software.

How to configure a Bluetooth link between instrument and Android device




Switch On the instrument.
Some Android applications automatically carry out the setup of a Bluetooth connection.
It is preferred to use this option if it exists. This option is supported by Metrel's Android
applications.
If this option is not supported by the selected Android application then configure a
Bluetooth link via Android device’s Bluetooth configuration tool. Usually no code for
pairing the devices is needed.
The instrument and Android device are ready to communicate.
Notes



Sometimes there will be a demand from the PC or Android device to enter the code.
Enter code ‘NNNN’ to correctly configure the Bluetooth link.
The name of correctly configured Bluetooth device must consist of the instrument type
plus serial number, eg. MI 3152-12240429I. If the Bluetooth module got another name,
the configuration must be repeated.
In case of serious troubles with the Bluetooth communication it is possible to reinitialize
the internal Bluetooth module. The initialization is carried out during the Initial settings
procedure. In case of a successful initialization “INITIALIZING… OK!” is displayed at the
end of the procedure. See chapter 4.6.5 Initial Settings.

Appendix B – Profile Notes
Instrument supports working with multiple Profiles. This appendix contains collection of minor
modifications related to particular country requirements. Some of the modifications mean
modified listed function characteristics related to main chapters and others are additional
functions. Some minor modifications are related also to different requirements of the same
market that are covered by various suppliers.
B.1 Profile Austria (ALAJ)
Testing special delayed G type RCD supported.
Modifications in chapter 7.6 Testing RCDs
Special delayed G type RCD selection added in the Selectivity parameter in Test Parameters /
Limits section as follows:
Selectivity
Characteristic [--, S, G]
Time limits are the same as for general type RCD and contact voltage is calculated the same as
for general type RCD.
Selective (time delayed) RCDs and RCDs with (G) - time delayed characteristic demonstrate
delayed response characteristics. They contain residual current integrating mechanism for
generation of delayed trip out. However, contact voltage pre-test in the measuring procedure
also influences the RCD and it takes a period to recover into idle state. Time delay of 30 s is
inserted before performing trip-out test to recover S type RCD after pre-tests and time delay of 5
s is inserted for the same purpose for G type RCD.
Table 7.1: Relationship between Uc and IN changed as follows:
