7.3.3 Programming the Test (F2 – Main Menu)
The test parameters of the individual tests on the Sartocheck
selected using the keypad. The Main Menu is the starting point for programming.
The following example uses a diffusion test to illustrate how to program data for
tests and running test sequences (F2 – Main Menu). The programming and test
sequences are identical for the other test types.
Before we start with the programming, let's first explain a few important key
commands.
The Sartocheck ® displays are set up with yellow buttons located on the right side
of the screen. These buttons always have the same functions:
Help: Starts the Online Help function
Main Menu: The program jumps back to the Main Menu (see Fig. 7-5)
Page Up: the program scrolls to the previous page of the screen
Page Down: the program scrolls to the next page of the screen
List Up: Whenever a list is displayed on the screen, use LIST UP
to scroll up the list
List Down: Whenever a list is displayed on the screen, use LIST DOWN
to scroll down the list
Enter: Confirms the selected function, action or entry.
Following confirmation, the yellow key turns gray
The respective functions can be activated using the unlabelled function keys to the
right of the display.
Programming Tests
Select the programs in the menu "Programming tests: Program selection". Already
existing programs can be selected by entering the program number in the field
provided for this purpose above the list or by marking. The selected line is
highlighted in blue. Scroll back and forth in the program selection list with List
DOWN|UP. Confirm the selected program line by pressing Enter. The Enter key
turns gray. If you would like to correct the program memory location, select a new
line number or highlight the new line directly on the touch screen.
Re-confirm by pressing Enter. Press PAGE DOWN to scroll to the next page.
The diffusion test is used as an example.

Diffusion Test

When pressure is applied to the upstream side of a wet filter, a diffuse gas stream
starts to flow through the filter membrane after a short time. The diffusion is
dependent on the effective filter surface, among other things. The diffusion test is
not suitable for testing disk filter systems. However, the diffusion test is a very well
suited test method for the integrity testing of medium-sized and larger filter
cartridge systems starting from approx. 150 cm
pressure, which means there is a direct correlation to the actual retention behavior
of the filter (for a more detailed description see Chapter 12, Appendix).
In the menu "Programming tests: Program selection", the test type is selected.
