1 About this manual
This document applies to the software version stated on the title page.
Product names may occur in the document, which are added for identification
purposes only and belong to the respective owner of the rights.
1.1 Target groups
This instruction manual is intended for the operator of the device and at technically
qualified specialists, with experience in the field of leak testing technology.
1.2 Warnings
DANGER
Imminent hazard resulting in death or serious injuries
WARNING
Hazardous situation resulting in potential death or serious injuries
CAUTION
Hazardous situation resulting in minor injuries
NOTICE
Hazardous situation resulting in damage to property or the environment
1.3 Definition of terms
Mention of helium in the manual
The device is a helium leak detector. If you want to use a forming gas instead of
helium to detect the hydrogen contained therein, the information for helium also
applies to hydrogen.

INFICON About this manual | 1
UL6000-Fab,-PLUS-Operating-instructions-iinc75en1-01-(2206) 9 / 152
Automatic tuning / mass setting
This function adjusts the mass spectrometer so that a maximum leak rate indicator is
achieved. In order to detect a maximum ion current with the ion detector, the control
computer adjusts the voltage for accelerating the ions within the selected mass range
accordingly.
During each calibration, there is an automatic adjusted.
Operation mode
The leak detector distinguishes between the "Vacuum" and "Sniffing" operation
modes. For the "Vacuum" operation mode, generally the tracer gas flows into the test
object. The pressure in the test object is less than the ambient pressure.
In the "Sniffing" operation mode, the tracer gas flows out from the test object and is
extracted with a sniffer probe. The pressure in the test object is greater than the
ambient pressure.
FINE
FINE designates the connection to the turbo molecular pump for medium inlet
pressures. This is also used for the "Sniffing" operation mode.
Forming gas
Forming gas is a collective term for gas mixtures of nitrogen and hydrogen.
GROSS
GROSS donates the connection to the turbo molecular pump with the lowest
sensitivity. This allows high inlet pressures.
Internal helium background
The measurement system of the leak detector also contains a residual amount of
helium. This creates an internal measurement signal component (background signal),
which overlaps the display of the leak right from the beginning and thus disturbs the
search for leaks.
So that this background signal can be suppressed, an internal "background
suppression" can be activated with the factory settings. When pressing the START
button, the currently internal measuring signal is counted as helium background and
subtracted from the measurement signal. If the leak detector has not been in the
"Standby" or "Vented" mode for 20 seconds, the last used internal helium background
is deducted.
Minimum detectable leak rate
The minimum detectable leak rate that can be detected by the leak detector under
ideal conditions.

10 / 152 UL6000-Fab,-PLUS-Operating-instructions-iinc75en1-01-(2206)
MASSIVE
After selecting the vacuum range "MASSIVE" gross leaks can now be measured from
atmospheric pressure.
ULTRA
ULTRA designates the connection to the turbo molecular pump for the measurement
range with the highest sensitivity at low inlet pressures.
ULTRATEST™ sensor-technology
Highly sensitive mass spectrometer for atomic masses 2, 3 and 4.
Background signal
Helium or hydrogen (as part of water) are natural components of air.
Operation mode "Vacuum": Before any leak detection, a certain amount of the
adjusted tracer gas is already in the volume on the surfaces of the test chamber,
supply lines, and even in the leak detector itself. This certain amount of tracer gas
generates a measurement signal which is called the "Background signal". The
ongoing evacuation of the test chamber continuously reduces this background signal.
Operation mode "Sniffing": Ambient air is continuously fed into the leak detector via
the sniffer line. The amount of helium or hydrogen occurring naturally in air creates a
constant background signal.
Foreline pressure
Pressure of the backing pressure between the turbo molecular pump and the backing
pump.
ZERO
There is helium that is weakly bound to the surfaces of a specimen as a natural part of
the ambient air and is pumped bit by bit into the measurement system of the leak
detector. It produces a slowly decreasing measurement signal.
If you want to hide this background signal or the display of existing leaks, then use the
ZERO function.

4.1 Function
The device is a leak detector for detecting and measuring leaks in test objects. The
device is suitable for leak detection using the vacuum method and the sniffer method.
It uses the ULTRATESTTM sensor technology.
• When using the vacuum method the test object is evacuated and subjected to
helium or forming gas from the outside. To do this it is necessary to establish a
vacuum connection between the device and the test object.
• When using the sniffer method an overpressure is established in the test object
using helium or a forming gas. The test object is then inspected on the outside
using a sniffer line.
Before performing leak tests, the leak detector should first be calibrated. See also
"Internal calibration [}75]" and "External calibration [}76]".
4.2 Operation modes
4.2.1 Operation mode "Vacuum"
The inlet flange is located on the upper side of the device.
To be able to perform leak detection using the vacuum method the inlet flange must
be connected to the desired test object.
If necessary, use a suitable reducer to connect the specimen to the inlet flange. An
adapter DN63 ISO-K/DN40 ISO-KF is included in the scope of delivery.
If the pressure in the specimen is less than the surrounding pressure, then helium
(which is sprayed over the specimen) can penetrate into the specimen if there is a
leak. Helium can be detected in the leak detector using a mass spectrometer.
HYDRO•S
With the operation mode "Vacuum" there is the possibility to use, HYDRO•S.
HYDRO•S reduces the time to measuring mode when using large test objects.
The desorption of water vapor in a test chamber produces an unwanted background
signal. HYDRO•S separates and suppresses this signal from the helium signal, so that
the test can start earlier. A new calibration is required after a change to this mode. In
the mode HYDRO•S the lower detection limit is 1 x 10-10 mbar l/s.

4.2.2 Operation mode "Sniffing"
To scan test objects under overpressure with a sniffer probe, you can connect the
SL200 sniffer line or the SL3000 sniffer line.
SL200 The vacuum connection of the sniffer line SL200 is connected to the upper side of the
device on the inlet flange.
The electrical connection of the sniffer line SL200 is connected to the connector
"ACCESSORIES" on the rear of the device, see "Connections for accessories and
control signals [}31]". An additional cable extension is required for the electrical
connection, see “Accessories and spare parts [}126]“.
SL3000 The sniffer line SL3000 is connected to the connection provided on the rear of the
device, see "Connections for accessories and control signals [}31]". Via this
connector both the electrical connection and the connection of the vacuum system is
made.
As no connection is made to the inlet flange on the upper side of the device, then no
vacuum components that are already connected to the inlet flange need to be
removed when changing to the operation mode "Sniff".
