batteries might explode!
Dangerous voltages are applied to the interior of the device! Disconnect all test
cables, disconnect the charger and switch off the installation tester before
opening the cover of the battery / fuse compartment.
Do not connect any voltage source to the C1 input. This input must be used for
connection of the current clamp adapters only. The maximum input voltage is 3 V!
Absolutely observe all common safety instructions in order to avoid the risk of an
electric shock when working on electrical installations!
Warnings with regard to measurements:
Insulating resistance
Measurements of the insulating resistance must be carried out only at test objects which
are free of voltage!
Never touch the test object during measurement before it is completely discharged!
Danger of life-threatening electric shocks!
If the insulating resistance is measured on capacitive test objects, discharging might
take place time-delayed! During discharge, the warning as well as the current
voltage are displayed until the voltage falls below 30 V.
Do not connect any measuring input to an external voltage higher than 550 V (AC or DC)
in order not to damage the installation tester!
Low-impedance measurement / continuity test
Low-impedance measurements / continuity tests must be carried out on discharged test
objects only!
The test result might be influenced by parallel impedances.
Testing the PE connection
If a phase voltage is detected at the PE connection, immediately stop all measurements.
Make sure that the error in the installation is eliminated before going on with the
measurements!

BENNING IT 130 Safety and operating instructions
Remarks with regard to measurements:
General
The icon means that the selected measurement cannot be carried out due to
irregular conditions at the input terminals.
Carry out measurements of the insulating resistance, low-impedance resistance,
continuity and earthing resistance on discharged objects only!
The "PASS" / "FAIL" indication is activated, if a limiting value has been defined. Choose
appropriate limiting values for evaluating the measuring results.
If only two of the three test cables are connected to the electrical installation to be
tested, only the voltage value between those two test cables shall be valid.
Insulating resistance
The three-wire test cable as well as the "Commander" test probe can be used for
measuring the insulating resistance.
If a voltage higher than 30 V (AC or DC) is measured at the testing terminals, the
measurement of the insulating resistance cannot be carried out.
The installation tester automatically discharges test objects after the measurement is
finished.
Double-click the "TEST" key to carry out a continuous measurement.
Low-impedance measurement / continuity test
If a voltage higher than 10 V (AC or DC) is measured at the testing terminals, the lowimpedance measurement / continuity test cannot be carried out.
Before carrying out a low-impedance measurement / continuity test, compensate the test
cable resistance (if necessary).
Earthing resistance
If a voltage higher than 30 V (AC or DC) is measured at the testing terminals, the
measurement of the earthing resistance cannot be carried out.
If an interference voltage higher than 5 V is detected at the testing terminals H and E or
S, the warning symbol "” will be displayed indicating that the measuring result might
have been influenced!
Residual current protection devices (RCDs)
The parameters set for a measuring function will be taken over for other RCD
measurements as well!
Contact voltage measurement usually does not involve any tripping of the residual
current protection devices (RCD). However, the tripping threshold might be exceeded
due to leakage currents via the protective conductor (PE) or via capacitive connections
between the conductors L and PE.
Compared to the loop impedance RL (contact voltage subresult), the measurement of
the loop impedance Zs
rcd
needs more time, but offers a considerably higher degree of
accuracy.
The tripping time and tripping current measurement is only carried out, if the contact
voltage at nominal differential current is lower than the preset limiting value of the
contact voltage.
The automatic test sequence (RCD AUTO function) is stopped, if the tripping time is
outside the admissible value.

stable during measurement.
Loop impedance measurements (Zs) involve tripping of residual current protection
devices (RCDs).
Loop impedance measurements (Zs
rcd
) normally do not involve tripping of the residual
current protection device (RCD). However, the tripping threshold might be exceeded due
to leakage currents flowing to the protective conductor (PE) or via the capacitive
connection between the conductors L and PE.
Line impedance / voltage drop
During phase-to-phase measurements of the line impedance ZI(L-L) with the test cables
PE and N being connected, a warning of dangerous PE voltages is displayed. However,
the measurement will be carried out.
The stated accuracy of the parameters tested shall only apply, if the mains voltage is
stable during measurement.
Depending on the connection voltage detected, the test terminals L and N are inverted
automatically.
Luminous intensity
Shadows and irregular exposure to light might influence the measuring result!
Artificial light sources reach their full capacity (see Technical Data of the light sources)
only after a certain time and therefore should be switched on until they reach this
capacity before carrying out measurements.
Testing the protective conductor connection (PE)
The PE connection can be tested only in switch positions "FI/RCD", "ZS(L-PE)" and
"ZI(L-N/L)"!
For correct measurement of the PE connection, the "TEST" key must be touched for
several seconds.
Make sure not to stand on an insulated floor, because otherwise the test result might be
incorrect!

2.2 Batteries / storage batteries and charger
The installation tester can be operated with six alkaline batteries (type AA) or with rechargeable
NiMh batteries (storage batteries). The specified operating time refers to storage batteries with
a nominal capacity of 2500 mAh. The batteries' state of charge is permanently displayed in the
lower right part of the LC display. If the battery voltage is too low, this will be displayed as
shown in figure 2.1. This indication is shown several seconds before the tester switches off.
Figure 2.1: Indication of discharged batteries
The rechargeable NiMh storage batteries will be charged automatically as soon as the charger
is connected with the charging jack of the installation tester. The polarity of the charging jack will
be displayed as shown in figure 2.2. An integrated protective circuit controls the charging
process and ensures an optimum battery lifetime.
Figure 2.2: Polarity of the charging jack
Symbol:
General warnings:
If the installation tester is connected to an installation, a dangerous voltage might be
applied to the battery compartment! Disconnect all test cables / accessories from the
installation tester and switch the installation tester off before replacing the batteries /
storage batteries and before opening the cover of the battery / fuse compartment!
Please make sure that the batteries / storage batteries are inserted correctly, because
otherwise the installation tester cannot be operated and the storage batteries will
discharge.
Do not recharge alkaline batteries!
Use only the charger included in the delivery!
Notes:
Before the first use! Insert the storage batteries into the battery compartment and charge
the storage batteries for at least 16 hours.
The charger inside the installation tester is a cell pack charger. This means that the
storage batteries are connected in series during charging. For this reason, the storage
batteries must be equivalent (same state of charge, same condition, same type and
same age).
If the installation tester is not used for a longer period of time, remove all storage
batteries from the battery compartment.
Use alkaline batteries or rechargeable NiMh batteries of size AA only! It is recommended
to use storage batteries with a minimum capacity of 2500 mAh.

BENNING IT 130 Safety and operating instructions
Unpredictable chemical processes might occur during the charging of storage batteries
that have not been used for a longer period of time (more than 6 months). In this case, it
is recommended to repeat the charging / discharging cycle at least 2 to 4 times.
If no improvement is achieved after several charging / discharging cycles, every storage
battery should be tested individually (by comparing the storage battery voltages, testing
by means of a cell charger etc.). It is very likely that only some of the storage batteries
have lost capacity. If one storage battery differs from the other ones, this might affect the
correct functioning of the entire storage battery block!
The effects described above must not be confused with the normal battery capacity
decrease over time. All rechargeable batteries (storage batteries) lose some of their
battery capacity when being charged / discharged several times. This information is
provided in the technical data specified by the battery manufacturer.

Typical applications are the following cases:
Insulating resistance between the active conductors (L/N) of an installation and the
protective conductor / earth (PE) => protection against electric shock,
Insulating resistance between the active conductors (L/N) of an installation => protection
against short-circuit (over-current) and guarantee of the functional safety,
Insulating resistance of non-conductive rooms (walls and floors),

Multiplier of testing current [½x, 1x, 2 x, 5xI
Note:
The limiting value of the contact voltage can be set only in the Uc sub-function.
Selective (delayed) RCDs have delayed tripping times. As the contact voltage
measurement and other RCD tests influence delayed RCDs, it takes a certain time until
they have returned to their normal condition. For this reason, a time delay of 30 seconds
is added before the standard tripping test is performed.
During testing of some portable PRCDs (e.g. PRCD-K) in which the protective conductor
is guided through the converter in opposite direction, this portable RCD trips already at
the 0.5-fold value of the nominal tripping differential current. The installation tester
evaluates the early tripping as "accidental tripping" and aborts the test without any
measuring result. If this test has been carried out with a positive result, i.e. it has been
proven that the portable PRCD trips at the 0.5-fold value of the nominal tripping
differential current and thus the protective conductor is not interrupted, it is possible to
continue the test by changing the contacting of the protective conductor. In this case, it
is necessary to establish a contact to the protective conductor (PE) of an adjacent
socket instead of establishing a contact to the protective conductor (PE) of the coupling
socket for further testing. Then, the test can be performed just as for an ordinary RCD.
The AC part of MI and EV RCDs is tested as standard (non-delayed) RCDs.
The DC part of MI and EV RCDs is tested with a smooth direct test current. The pass
limit is between 0.5 x and 1.0 x I

5.4.1 Contact voltage (Uc)
Leakage current flowing to earth via the protective conductor connection causes a voltage drop
at the earthing resistance, i.e. a voltage difference between the PE equipotential bonding and
earth. This voltage difference is called contact voltage and is applied to all accessible
conductive parts connected to protective earth (PE). The contact voltage always should be
lower than the maximum admissible contact voltage. Contact voltage is measured with a testing
current lower than ½ I∆N in order to avoid tripping of the RCD and then to be normalized to the
nominal value I∆N.
How to perform contact voltage measurements
Select the FI/RCD function by means of the function selector switch.
Set the sub-function to Uc.
Set the testing parameters.
Connect the test cables to the test object (see figure 5.17).
Press the "TEST" key to start the measurement.
Save the measuring result by pressing the "MEM" key (optional).
The contact voltage displayed refers to the rated differential current of the RCD and is

exceedance of the maximum admissible contact voltage or a tripping time outside the
admissible range.
During the automatic testing of RCDs of the types A and F with nominal tripping
differential currents of 300 mA, 500 mA and 1000 mA, the test of 5×I∆N will not be
carried out. In this case, the test shall be passed, if all other test have been passed.
The tripping current measurement (I , steps 7 and 8) is not carried out for selective
RCDs.
Trip out time measurement of RCDs of the types B and B+ in AUTO function is effected
with sinusoidal testing current, while trip-out current measurement is effected with a
smooth direct current.

5.8 Testing the protective conductor connection (PE)
In case of new or modified installations, it might happen that the protective conductor (PE) and
the external conductor L (phase) have been accidentally reversed. This is a very dangerous
situation! For this reason, it is important to check whether a dangerous phase voltage is applied
to the protective conductor connection.
The test of the protective conductor connection is performed automatically for the ZIine (L-N/L),
Zloop (L-PE) and RCD measuring functions by touching (> 1 second) the silver "TEST" key of
the installation tester, of the "Commander" test probe or the optional "Commander" test plug
(044149).

5.10 Single-fault leakage current (ISFL) in IT networks
The IT system is a power supply network which is insulated from the protective conductor. It is
an ungrounded power supply network. Either the network is not connected to earth directly or it
is connected to earth via a relatively high impedance. It is mainly used in areas requiring
additional protection against electrical accidents. A typical area of application are medical
operating rooms.
A first insulation fault between an external conductor and earth represents earthing of this
conductor. In this case, there is neither a potential difference between conductive housings and
earth nor an electric circuit to the transformer closed via earth.
The measurement of the single-fault leakage current is carried out in order to measure the
maximum current which might flow from the tested line (external conductor) to the protective
conductor. This current flows through the insulating resistance and the phase-to-earth
capacities between the other lines (external conductors) and the protective conductor, if the
single fault is applied as short-circuit between the tested line and PE.
