1 General Information
Notice: We recommend that you carefully read this technical handbook to ensure
optimum operating conditions right from the start.
This technical handbook contains important informations on the functions, instal-
lation, start-up and operation of the UL5000.
General
We reserve the right to modify the design and the specified data. The illustrations are
not binding.
1.1 Notes on the Use of this Handbook
1.1.1 Safety Symbols
Important remarks concerning operational safety and protection are emphasised as
follows:
Caution
Information on correct handling or use. Disregard can lead to malfunctions or minor
equipment damage.
Warning
Information on preventing extensive equipment and environmental damage.
STOP Danger
Information on preventing any kind of physical injury.
Skilled personnel
Indicates procedures that must be performed by skilled personnel only.

General Information 7
iina74e 01.fm technical handbook(1408)
1.1.2 Indications
Tipp Information on helpful procedures.
Notice: Information on special technical requirements that the user must comply
with.
The references to diagrams consists of the Chapter number, figure number and the
item number in this order. For example: Fig. 2-4/7 refers to item 7 in the figure 4 of
Chapter 2.
1.1.3 Symbols of Vacuum Technology
Given in the following are some important vacuum symbols which are used in this
manual.
Vacuum pump in general
Turbomolecular pump
Pressure gauge
Valve
1.1.4 Definition of Terms
Autoranging
The range of the preamplifier and the vacuum ranges are selected automatically.
The autoranging feature of the UL5000 covers the entire range or leak rates
depending on the selected operating mode. Not only the leak rate signal, but also the
pressure in the test sample (inlet pressure P1) and the fore vacuum pressure (P2)
are used for control purposes. Range switching between the main ranges is
performed via valves. Fine range switching within the main ranges is implemented
by switching over the gain factor of the preamplifier.
Autotune Mass alignment
This function automatically aligns the mass spectrometer so that a maximum leak
rate is displayed. The control processor changes the voltage which erates the ions
in the selected mass range until a maximum ion current is detected by the ion
detector. During each calibration the mass alignment is run automatically.

8General Information
iina74e 01.fm technical handbook(1408)
Auto zero
Determination and automatic adaptation of the helium background.
Through this function, the internal zero level of the instrument is determined which is
then subtracted from the current leak rate signal. This function is run during the cali-
bration process or when operating the start pushbutton, provided the UL5000 has
been running previously for at least 20 seconds in the standby or vent mode. If the
helium background previously suppressedshould dropso that for the duration of the
zero time only the display limit will be displayed, the zero level is adapted automati-
cally.
Menu
Themenu allowsthe usertoprogramthe UL5000 according to his requirements.The
menu has a tree architecture.
Default
Status of the UL5000 when supplied by the factory.
GROSS
GROSS is a measurement mode which allows high inlet pressure (1 to 15 mbar).
The smallest detectable leak rate is 1×10-6 mbar l/s.
FINE
FINEisthemediummeasurementmodewithinletpressurebetween2and0,4 mbar.
Detection limit is 1×10-10 mbar l/s.
ULTRA
ULTRA is the most sensitive measuring range with inlet pressures below 0,4 mbar.
The minimum detectable leak rate is < 5×10-12 mbar l/s.
Foreline pressure
Pressure in the foreline between Turbo pump and scroll pump.
Minimum detectable leak rate
The smallest leak rate the UL5000 is able to detect (5E-12 mbar l/s).
Internal helium background
The existing helium partial pressure in the measurement system. The level of the
internal helium background is measured in the Stand-by mode and subtracted from
the measured signal.
Measure Measurement mode
The UL5000 measures the leak rate of the test sample.

1.2 Support from INFICON Service
If an instrument is returned to INFICON or an authorised representative of INFICON,
please indicate whether the instrument is free of substances damaging to health or
whether it is contaminated.Ifitiscontaminatedalsoindicatethenatureofthehazard.
INFICON must return any appliances without a Declaration of Contamination to the
sender’s address. A form for stating details as to the type of contamination is repro-
duced in Fig. 1-1.
A maintenance and service contract is recommended.
