x <ENTER>
The test reads the code continuously and displays it immediately. For representation on the
screen a 6-place bit pattern is provided (code ??????). The first position is for magnet no. 1, the
second position for magnet no. 2, etc. If a magnet is recognized, a “1” is written into the corre-
sponding position, otherwise a “0” is assigned.
x Position all racks which are used one after the other and compare
the notes made before the test with the information on the display.
>rack code test
code 000000
Example for:
no rack in position
>rack code test
code 011000
Example for:
Rack with a code as in the example above
x The test can be stopped by pressing the <QUIT> or <STOP> keys.

>function test
The diagnosis can be exited from the main menu with <QUIT> or
<STOP>.
6.5 Initialize data memory
This diagnostic step can be used to write default values to the instru-
ment parameters using the keypad and thus switch the instrument to
the original condition. This measure is important with the following two
points:
The setting of certain instrument parameters such as the locking of
keys is possible only via RS232, i.e. with the aid of a PC. If such in-
strument parameters are set and no PC is available to cancel the set-
tings, full use can not be made of the instrument.
In rare cases, it is possible that major interference signals such as line
spikes and lightning can have an adverse influence on the contents of
the data memory. If the contents of the data memory are undefined,
this may lead to a system crash.
The 788 IC Filtration Sample Processor offers various possibilities to ini-
tialize the data memory. The entire data memory ( all ) or only parts of it
(param, config, setup, assembly
) can be written to with default val-
ues.
Although the instrument number and the standard methods will be re-
tained, the entire data memory initialization ( all ) should be performed
only if necessary as the stored user methods are deleted.
