10.6 System initialization
In very rare instances, a faulty file system (e.g. because of a program
crash) may lead to an impairment of program functioning. The internal file
system must be initialized in such cases.
Caution
All user data (methods, etc.) are deleted if a system initialization is car-
ried out. Afterwards, the instrument will have the factory settings again.
We recommend creating a backup of the system at regular intervals in
order to avoid data losses.
After a system initialization the program versions and language files do
not have to be reloaded. Only the selection of the dialog language may
have to be reset in the system settings.
Proceed as follows for the system initialization:
1 Switching off the instrument
￭ Keep the red [STOP] key pressed down for at least 3 s.
A progress bar is displayed. If the key is released during this time,
then the instrument will not be switched off.
2 Switching on the instrument
￭ Keep the red [STOP] key pressed down for approx. 10 s.
The dialog for confirmation of the initialization is displayed for 8 s.
The initialization must be confirmed during this time.
