6 Menu Level / Sampling of Functional Values
To sample functional values press the “Menu” key. Whenever you
jump to the menu level the screen shown on the right appears
indicating the installed software (for ex. S4 002). Use the +/- keys
to display the other menu screens.
To quit the menu level and enter the operating level press the
“Menu” key again. If 60 seconds elapse without a key being pressed
the system will automatically return to the operating level.
It is not possible to make changes to the appliance from the menu
level. Exception: The only exception to this is the I/O key, with which
you can switch the appliance on and off even when working at the
menu level. The I/O key is also active at the menu level.
Important Note:
Whenever any of the codes shown in the following table appear on the display this
means you are at the menu level. It is not possible to operate the appliance from this
level (except switch it “ON/OFF” via the I/O key).
