After start-up, the left and right display with touch screen show the same content. Both displays have
the same functionality and can at the same time or alternatively be used to operate the instrument.
If e.g. a PPS 400.3 source module is controlled via Bluetooth, one display can be used to control the
source and the other to control the reference standard.
After start up the Reference Menu Card (MC) is
displayed in the form of a register card with the
Logo cycling between MTE and EMH.
The various selectable functions of the menu are
shown at the left-hand side of the display in the
form of Functional Buttons (FB) with graphical in-
dication of the function.
At the bottom status information is displayed.
The function (Reference) is indicated in the menu card. This MC includes all operating
functions of the built-in reference standard. The MC Data Base, which includes basic set-
tings of the instrument, is always active.
