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 CE MultiTesterXA 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!
Use only standard or optional test accessories supplied by your distributor!
Only test adapters provided or approved by Metrel should be connected to TC1
(test and communication) connectors.
Use only earthed mains outlets to supply the instrument!
In case a fuse has blown refer to chapter 8.2 Fuses in this Instruction manual to
replace it!
Instrument servicing and calibration is allowed to be carried out only by a
competent authorized person!
Metrel is not responsible for the content of the user-programmed Auto
Sequences®!
1.1.2 Warnings related to safety of measurement functions
1.1.2.1 HV AC, HV DC, HV AC programmable, HV DC programmable

MI 3394 CE MultiTesterXA General description
8
A dangerous voltage up to 5 kVAC or 6 kVDC 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 Diff. Leakage, Ipe Leakage, Touch Leakage, Power, Leak’s & Power
Load currents higher than 10 A can result in high temperatures of fuse holders and
On/Off switch! 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
Do not touch the test object during the measurement or before it is fully discharged!
Risk of electric shock!
1.1.3 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.
Mark on your equipment certifies that this equipment meets the requirements
of the all applicable EU (European Union) regulations.
This equipment should be recycled as electronic waste.

4.3 Safety checks
At start up and during operation the instrument performs various safety checks to ensure
safety and to prevent any damage. These safety pre-tests are checking for:
Correct input mains voltage
Presence of input PE connection,
Any external voltage against earth on mains test socket
Excessive leakage currents through measuring I/Os,
Too low resistance between L and N of tested device,
Proper operation of safety relevant internal electronic circuits
If a safety check fails, an appropriate warning message will be displayed and safety
measures will be taken. The warnings and safety measures are described in chapter 4.4
Symbols and messages.
4.4 Symbols and messages
Supply voltage warning
Possible causes:
No earth connection.
Instrument is connected to an IT earthing
system. Press YES to continue normally or NO
to continue in a limited mode (measurements are
disabled).
Warning:
The instrument must be earthed properly to work
safely!
Resistance L-N > 30 kΩ
In pre-test a high input resistance was measured.
Possible causes:
Device under test is not connected or switched
on
Input fuse of device under test is blown.
Select YES to proceed with or NO to cancel
measurement.
Resistance L-N < 10 Ω
In pre-test a very low resistance of the device under test
supply input was measured. This can result in a high
current after applying power to the device under test. If
the too high current is only of short duration (caused by
a short inrush current) the test can be performed
otherwise not.
Select YES to proceed with or NO to cancel
measurement

MI 3394 CE MultiTesterXA Instrument operation
14
Resistance L-N < 30 Ω
In pre-test a low input resistance of the device under
test was measured. This can result in a high current
after applying power to the device. If the high current is
only of short duration (caused by a short inrush current)
the test can be performed, otherwise not.
Select YES to proceed with or NO to cancel
measurement.
Warning for improper supply voltage condition. If
pressing OK instrument will continue to work in a limited
mode (measurements are disabled).
In pre-test an external voltage between C1/P1 and
C2/P2 terminals was detected. The measurement was
cancelled. Press OK to continue.
In pre-test a too high external voltage was detected
between P and PE terminals. The measurement was
cancelled. Press OK to continue.
In pre-test a too high external voltage was detected
between ISO/SUB and PE terminals. The measurement
was cancelled. Press OK to continue.
In pre-test a possible high leakage current was
detected. It is likely that a dangerous leakage current
(higher than 3.5 mA) will flow after applying power to the
device under test.
Select YES to proceed with or NO to cancel
measurement.
The measured leakage (Idiff, Ipe, Itouch) current was
higher than 20 mA. Measurement was aborted. Press
OK to continue.

MI 3394 CE MultiTesterXA Instrument operation
15
The load current exceeded the highest upper limit of 10
A for the Discharging time test. Measurement was
aborted. Press OK to continue.
The load current continuously exceeded 10 A for more
than 4 min (moving average) in Power and Leakage
tests. Measurement was stopped for safety. Press OK
to continue.
The load current exceeded the highest upper limit of 16
A for the Power and Leakage tests. Measurement was
aborted. Press OK to continue.
Warning for restart of the instrument to set new Ethernet
settings. This message appears on exit from Settings
menu after changing Ethernet settings. Press OK to
continue.
The instrument is overheated. The measurement can’t
be carried out until the icon disappears. Press OK to
continue.
The device under test should be switched on (to ensure
that the complete circuit is tested).
Test voltage in Insulation resistance measurement is too
low.
Measurement result is scaled to 110 V.
Red dot indicates phase of measurement where higher
leakage was measured. Applicable only if phase
reversal is enabled during the measurement.
Test leads resistance in Continuity P/S - PE
measurement is not compensated.
Test leads resistance in Continuity P/S - PE
measurement is compensated.
Warning!
A high voltage is / will be present on the instrument
output! (Withstanding test voltage, Insulation test
voltage, or mains voltage).
Warning!
A very high and dangerous voltage is / will be present
