4.2 Menu control via alphanumerical display
The dialogue between the user and the control of the device is via the alphanumerical display. It
serves for menu-prompted parameterising of the device. During a measurement, it provides infor-
mation on the most important measuring variables and displays possibly occurring faults.
Thanks to the simple structure of the menu, the user can determine the required test parameters
in just a few steps.
The entire selection of functions and parameterisation are performed with the rotary encoder
[ < Select > ] and the buttons [Enter] and [Cancel] . Turning the rotary encoder counterclockwise or
clockwise, as appropriate, will shift the cursor (highlighting of a function) or change a parameter. The
rotary encoder has no end stop.
Pressing the button [Enter] will acknowledge a selected function or a selected parameter. That is,
you get to the next menu level.
By pressing the button [Cancel] , you can cancel the selection of a function or of a parameter.
Each time you press this button will bring you one further level back in the menu.
