Setting the audio
alarm

Output of an acoustic signal depending on the leak rate--- No sound
Proportional: The frequency of the audible signal is proportional to the bar graphdisplay or diagram height. The frequency range is 300Hz to 3300Hz.
Setpoint: The pitch is proportional to the leak rate. The signal sounds if the leak rate
exceeds the selected trigger value.
Pinpoint: The sound of the acoustic signal changes its frequency within a specificrange of leak rates. Range: A decade below the selected trigger threshold up to one
decade above. The sound keeps at a constant low and a constant high frequency
below and above this range, respectively.
Trigger: If the selected trigger threshold is exceeded, a two-pitch signal sounds.

Control unit

Settings > Set up > Control unit > Audio > Audio alarm mode

Behavior with warnings or error messages: If the touch screen shows a warning or
an error, then a two-pitch signal sounds simultaneously.
Automatic switch off

The touch screen can be switched off automatically after a specific time without anyof the touch screen

operation to save energy.

For the types "Integrator", "Supervisor" and "Operator", a four-digit PIN must be
assigned during registration (0000 ... 9999). "0000" is assigned to all operators ex
works.
If an operator keeps the pin "0000", this operator will always be registered is during
the start up of the system (without PIN query).
A key-operated switch can be used in addition to a PIN if an I/O module is connected.
The key-operated switch is connected to the I/O module via three digital inputs (seeoperating instructions of the LDS3000).

6.3.6 Display equivalence leak rate for other gas
Scope
The explanations on the equivalence rate only refer to sniffing operation.
If you measure with the test gases helium or hydrogen, but want to display anothergas with its leak rate, use a correction factor for the test gas used.

up, see "Touch screen settings [} 17]", ”Assigning favorite buttons”.

You have a choice of two methods:• To conveniently set the correction factor, use the "Gas equivalent selection[} 27]". There, the correction factor can be selected from a self-defined list, see"Configure gas list [} 28]", or switched back to the tracer gas.
• Alternatively, it is possible to calculate and configure the correction factor. For
information on calculation, see "Calculate equivalence factor [} 29]". For
information on configuring the device, see "Set equivalence factor and molar mass[} 30]".

In the window "Gas equivalent selection", you can respond to different
situations:ð If the desired gas equivalent is already stored (numbers 1 to 4), select thedesired gas equivalent number and confirm with "OK". The gas name and theequivalence factor of this gas equivalent are then displayed at the top left inthe measuring window. You can perform measurement.

INFICONð If the desired gas equivalent is not stored, it must be configured, see"Configure gas list [} 28]".
ð If you do not find a suitable entry in the 4 gas equivalents and also do notwant to change these, you can calculate the correction factor as analternative. In the window "Gas equivalent selection" select the entry "Userdefined" and configure the correction factor, see "Set equivalence factor andmolar mass [} 30]".
ð If you want to switch from the display of the gas equivalent in the measuringwindow back to the measurement value of the measuring gas, select "Switchoff" and confirm with "OK".
The options "Switch off" and "Gas equivalent no. 1...4" overwrite parameters, see "Setequivalence factor and molar mass [} 30]".
If you select the option "User-defined", parameters then have to be configured, see"Set equivalence factor and molar mass [} 30]".

6.3.6.2 Configure gas list
You can predefine up to 4 equivalence gases and assign names to them. The
equivalence gases can then be selected in the gas equivalent selection, see "Gasequivalent selection [} 27]".

Control unit: Settings > Set up > Operation modes > Equivalence leak rate >Configure gas list2

Select one of the numbers 1 to 4.
ð A set of parameters is displayed for each stored gas. If there is an unusedentry, "No Entry" is displayed.

3

Press the button "Edit".
ð If you want to detect one of the gases from the stored gas library, press thedesired entry. See also "Gas library [} 36]".
ð If the desired gas is not stored, scroll to the end of the gas library and select"User-defined gas". Then, assign a name of your choice in the window"Equivalence gas name" and confirm your choice. Then enter the molar mass
and viscosity factor of the equivalence gas. For all gases that are notavailable in the gas library, please feel free to contact INFICON.

4Make your customer-specific entries in the following windows, which arebrought up by the assistant, first "Absolute pressure equivalence gas".
ð Corresponds to the absolute pressure of the equivalence gas in the test
object in bar.

ð This is the gas proportion of the tracer gas in percent, e.g. for forming gas(95/5) it would be 5%.
7

Window "Absolute pressure measuring gas".
ð Corresponds to the absolute pressure of the tracer gas in the test object inbar.

ExampleAn air conditioning system is to be checked for leaks. The system is first filled with 2
bar (absolute) pure helium and checked for leaks. Later the plant will be filled with
R134a. The operating pressure is 15 bar (absolute).
This results in the following values for the above-specified parameters:
Absolute pressure equivalence gas = 15.0
Measuring mass = 4
Percentage of measuring gas = 100.0
Absolute pressure measuring gas = 2.0

6.3.6.3 Calculate equivalence factor
The equivalence factor is not calculated by the software of the device. Calculate theequivalence factor using the following formula:

Dynamic viscosity of test gas (helium or H2)
Dynamic viscosity of the equivalent gas
Absolute pressure of the test gas in the test object in bar
Absolute pressure of the equivalent gas in the test object in bar

ExampleAn air conditioning system is to be checked for leaks.
The system is first filled with 2 bar (absolute) helium and checked for leaks. Later theplant will be filled with R134a. The operating pressure is 15 bar (absolute).
The dynamic viscosity of helium is 19.62 µPa*s.
The dynamic viscosity of R134a is 11.49 µPa*s.
In order to obtain an R134a equivalent leak rate display during the helium leakdetection, the following equivalence factor must be entered:

Software updates from INFICON are installed with the aid of a USB flash drive. The
update function of the device can be found under "Functions > Data > Update".
An update is possible,• if one or several updates are available on the USB flash drive, but only one update
per type at most (control unit, MSB box, I/O module),• if these parts are also connected free of disturbances and have an update
function.
The corresponding buttons in the update menu such as "Control Unit", "MSB Box",and "I/O Module" are active and can be activated individually.

NOTICE
