2 Safety and operational considerations
2.1 Warnings and notes
In order to maintain the highest level of operator safety while carrying out various tests and
measurements, METREL recommends keeping your Eurotest instruments in good condition
and undamaged. When using the instrument, consider the following general warnings:
General warnings related to safety:
The symbol on the instrument means »Read the Instruction manual with
special care for safe operation«. The symbol requires an action!
If the test equipment is used in a manner not specified in this user manual, the
protection provided by the equipment could be impaired!
Read this user manual carefully, otherwise the use of the instrument may be
dangerous for the operator, the instrument or for the equipment under test!
Do not use the instrument or any of the accessories if any damage is noticed!
Consider all generally known precautions in order to avoid risk of electric shock
while dealing with hazardous voltages!
In case a fuse has blown follow the instructions in this manual in order to replace
it! Use only fuses that are specified!
Do not use the instrument in AC supply systems with voltages higher than
550 Va.c.
Service, repairs or adjustment of instruments and accessories is only allowed to
be carried out by a competent authorized personnel!
Use only standard or optional test accessories supplied by your distributor!
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 III600 V / CAT IV300 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.
All normal safety precautions must be taken in order to avoid risk of electric
shock while working on electrical installations!

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!
When an insulation resistance measurement has been performed on a capacitive object,
automatic discharge may not be done immediately! The warning message and the
actual voltage are displayed during discharge until voltage drops below 30 V.
Do not connect test terminals to external voltage higher than 600 V (AC or DC) in order
not to damage the test instrument!
Continuity functions
Continuity measurements should only be performed on de-energized objects!
Parallel loops may influence on test results.
Testing PE terminal
If phase 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!
Notes related to measurement functions:
General
The indicator means that the selected measurement cannot be performed because
of irregular conditions on input terminals.
Insulation resistance, continuity functions and earth resistance measurements can only
be performed on de-energized objects.
PASS / FAIL indication is enabled when limit is set. Apply appropriate limit value for
evaluation of measurement results.
In the case that only two of the three wires are connected to the electrical installation
under test, only voltage indication between these two wires is valid.
Insulation resistance
The standard three-wire test lead, schuko test cable or Plug / Tip commanders can be
used for the insulation test with voltages ≤ 1kV.
If a voltage of higher than 30 V (AC or DC) is detected between test terminals, the
insulation resistance measurement will not be performed.
The instrument automatically discharge tested object after finished measurement.
A double click of TEST key starts a continuous measurement.
Continuity functions
If a voltage of higher than 10 V (AC or DC) is detected between test terminals, the
continuity resistance test will not be performed.
Compensate test lead resistance before performing a continuity measurement, where
necessary.

MI 3100 s, MI 3100 SE EurotestEASI Safety and operational considerations

Earth resistance
If voltage between test terminals is higher than 30 V the resistance to earth
measurement will not be performed.
If a noise voltage higher than approx. 5 V is present between the H and E or S test
terminals,“” (noise) warning symbol will be displayed, indicating that the test result
may not be correct!
RCD functions
Parameters set in one function are also kept for other RCD functions!
The measurement of contact voltage does not normally trip an RCD. However, the trip
limit of the RCD may be exceeded as a result of leakage current flowing to the PE
protective conductor or a capacitive connection between L and PE conductors.
The RCD trip-lock sub-function (function selector switch in LOOP position) takes longer
to complete but offers much better accuracy of fault loop resistance (in comparison to
the RLsub-result in Contact voltage function).
RCD trip-out time and RCD trip-out current measurements will only be performed if the
contact voltage in the pre-test at nominal differential current is lower than the set contact
voltage limit!
The auto-test sequence (RCD AUTO function) stops when trip-out time is out of
allowable time period.
Z-LOOP
The low limit prospective short-circuit current value depends on fuse type, fuse current
rating, fuse trip-out time and impedance scaling factor.
The specified accuracy of tested parameters is valid only if the mains voltage is stable
during the measurement.
Fault loop impedance measurements will trip an RCD.
The measurement of fault loop impedance using trip-lock function does not normally trip
an RCD. However, the trip limit may be exceeded if a leakage current flows to the PE
protective conductor or if there is a capacitive connection between L and PE conductors.
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.
L and N test terminals are reversed automatically according to detected terminal voltage
(except in UK version).
Testing PE terminal
PE terminal can be tested in RCD, LOOP and LINE function selector switch positions
only!
For correct testing of PE terminal, the TEST key has to be touched for a few seconds.
Make sure to stand on non-isolated floor while carrying out the test, otherwise test result
may be wrong!
PE conductor resistance (MI 3100 SE)
The specified accuracy of tested parameters is valid only if the mains voltage is stable
during the measurement.

PE conductor resistance measurement will trip an RCD.
The measurement of PE conductor resistance using trip-lock function does not normally
trip an RCD. However, the trip limit may be exceeded if a leakage current flows to the
PE protective conductor or if there is a capacitive connection between L and PE
conductors.
Autosequence tests (MI 3100 SE)
See notes above for selected tests in Auto-sequence.

2.2 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 lower right display part. In case the battery is too weak the instrument
indicates this as shown in figure 2.1. This indication appears for a few seconds and then the
instrument turns itself off.
Figure 2.1: Discharged battery indication
The battery is charged whenever the power supply adapter is connected to the instrument. The
power supply socket polarity is shown in figure 2.2. Internal circuit controls charging and
assures maximum battery lifetime.

Warnings related to safety:
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 !
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 2100mAh 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,

MI 3100 s, MI 3100 SE EurotestEASI Safety and operational considerations
12
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.
