29.1 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
If you carry out a system initialization, then all user data except the
methods will be deleted.
We recommend creating a backup of the system at regular intervals in
order to avoid data losses.
Proceed as follows for the system initialization:
1
Switching off the instrument
ï¿ Press the power switch at the rear.
2
Switching on the instrument
ï¿ Press the power switch at the rear.
An image with a frog will be displayed after a couple of seconds.
ï¿ While the image is being displayed, press the power switch again
and hold it down.
ï¿ Do not release the power switch until an acoustic signal sounds.
A system message is displayed.
3
Confirm system initialization
ï¿ Confirm the message with [Yes].
A second safety prompt is displayed.
ï¿ Confirm this message with [Yes] as well.
Initialization is started. After the initialization has been completed,
the 917 Coulometer is started automatically.
