7.18. Resetting the default settings (21. menu item)
Function
In this case all the settings are deleted, and the default
factory setting is restored.
Using this function makes sense in that case, when the
settings of the instrument have changed so much, that it is
easier to start the setting-up process from the default
factory setting.
It is not possible to cancel this operation once the command
has been issued.
Sequence of operations 1. Enter the menu by typing the supervisor code.

3. Enter the menu item by pressing the
ENTER button.

is shown on the display. The

exit, as you do not want to reset the default settings after all,
press the
MENU button. This takes you out from this menu
item, and you see this:

.
6. Press the ▲ button to set

