5.5 Initialize data memory
This diagnostic step can be used to write default values to the in-
strument parameters using the keypad and thus switch the instru-
ment 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
settings, 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 730 Sample Changer offers various possibilities to initialize
the data memory. The entire data memory (
all ) or only parts of it
(param, config, setup, assembly ) can be written to with default
values.
Although the instrument number will be retained, the initialization
should be performed only if necessary as the stored user data
(etc.) are deleted.
