2 Safety
2.1 Intended use
The test chamber is designed for leak testing of Li-ion cells and Li-ion batteries.
Uncharged cells/batteries can be tested safely. For testing charged cells/batteries,
further safety measures must be taken to avoid personal injury and damage to
property.
• For validation of the test, cells prepared as leaky are placed in the chamber. The
preparation of the cells, which creates further hazards, is performed by the
operator and is not an integral part of the test or the device. Testing of leaking
cells will result in soiling of the test chamber and possibly "contamination". Cells to
be tested with the test chamber must be pre-qualified. For this purpose,
uncharged cells are examined, for example, to determine whether they can
withstand the stresses of the leak testing. Suitable measures for the safety of man
and machine must be taken by the operator.
• The test objects must be filled with an electrolyte in which one solvent component
ideally consists of dimethyl carbonate (DMC, CAS No. 616-38-6).
• Depending on the internal structure of the test objects and the external
geometries, local mechanical stresses can occur on the test objects. This can
damage the test objects themselves, but also other components located in the test
chamber.
• Make sure that the test chamber and the outer wall of the test objects are clean.
Leak testing with charged test objects represents an additional safety risk and
should only be carried out by appropriately trained personnel and with the
installation of further safety measures.
• To avoid short circuits between the test object and chamber wall, use the insulator
included in the scope of delivery.
• An external pump may optionally be connected to the ISO-KF16 connection
according to the specifications in the documentation. The pump is not included in
the scope of delivery. The pump capacity must be at least 40 L/min up to 1000 L/
min. The optional external pump must be connected via an electrically switchable
valve, a corrugated hose and, if required, a suitable adapter.
Incorrect usage Avoid the following unintended uses:
• Testing of partially or fully charged cells and batteries without further safety
measures.
• Use outside the technical specifications, see "Technical Data".
• Testing of non-vacuum Li-ion cells, batteries or other test objects.

• Testing of Li-Ion cells, batteries or other test objects that cannot withstand the
stresses that occur during testing. Depending on the internal structure of the test
objects and the external geometries, local mechanical stresses can occur on the
test objects. This can damage the test objects themselves, but also other
components in the test chamber.
• Testing of test objects whose current collectors can be short-circuited via the test
chamber (e.g. via the lid or other conductive parts).
• Testing of test objects that come into contact with the sealing lips of the chamber.
• Testing of wet or moist test objects.
• Testing of test objects with significant temperature differences to the environment.
• Testing of damaged test objects, batteries or other test objects.
• Testing of test objects without insulator.
• Testing of components or substances other than lithium-ion batteries.
• Testing of contaminated test objects.

• Operation of the chamber by inadequately trained personnel.
• Insufficient distance between the test objects in the test chamber.
• Use beyond the technical specifications.
• Use in radioactive areas.
• Closing the test chamber while your fingers are in the rotation range of the test
chamber.
• Use of unauthorized accessories or spare parts.
• Mounting by untrained or unauthorized personnel. Only trained personnel or
INFICON employees are permitted to carry out the assembly.
• Interchanging the exhaust air ("INLET") and supply air ("VENT") lines on the
ELT3000.
• Pumping out liquids or vapors that can condense.
• Using an improperly dimensioned optional external pump.
• Use of the optional pump connection for abrupt venting.
• Testing of test objects that are too small or too light and may move uncontrollably
during venting.
• Use of tools that may damage the sealing surfaces of the test chamber during
mechanical cleaning.

4.1 Function
The test chamber, in conjunction with the Gas Control Unit of the ELT3000, makes it
possible to perform leak testing on test objects. Test objects that are not vacuum-tight
can thus be tested for leak tightness.
Place the test object in the test chamber. By pumping out the air from the test
chamber, a pressure gradient between test object and test chamber is generated.
Due to this pressure gradient, gas flows through leakages out of the test object and
into the test chamber. This gas is sent to the GDU (Gas Detection Unit) for analysis.
After the analysis, the result is compared with the setpoint. A distinguishable leak-
proof/leaky signal is output.
4.2 Markings on the device
The markings on the device have the following meanings:
Device cannot be disposed of as normal domestic waste.
Note: Only put objects that are obviously undamaged and vacuum-tight in
the device.

CAUTION
Uncontrolled movements of chamber lid or test objects
An incorrectly selected or incorrectly connected external pump can lead to hazards
from the lid or test objects, which can move uncontrollably due to excessive air flows.
► Only use an external pump that complies with the permitted technical data.
► When installing and commissioning an external pump, be sure to follow the
instructions below.
To increase the pumping capacity, you can connect an external pump to the ISO-
KF16 connection. The ISO-KF16 connection is closed with a blind flange when
delivered. To do this, connect an electrically switchable valve with a minimum nominal
diameter of DN4 to the ISO-KF16 connection. The valve must be suitable for a
pressure range of at least 0 to 1.5 bar (absolute). This enables the external pump to
be switched on and off later. When using an IO1000 module connected to the
ELT3000, the valve can be switched via one of the PLC outputs. Please note that the
valve is switched with 24V, with a maximum current consumption of 0.75 A. You can
connect a suitable pump to the valve via a corrugated hose and adapter. For this
