and the colour mode. If you choose the top menu item PAPER
FORMAT with the associated soft menu key, a window will open

the universal knob to select the desired format which will then

The next lower menu item COLOR MODE allows the selection
of the modes Greyscale, Color and Inverted following the same
procedure. The Greyscale mode converts a color display to a
greyscale display which can be printed on a Black-and-White
Postscript printer. The Color Mode will print the display in
colour as it is shown on the screen (black background). In the
Inverted Mode the color display will be printed in colour with a
white background on a color Postscript printer in order to save

Self Alignment
The HMF series has an internal self alignment procedure in
order to achieve an improved frequency response and a more
accurate offset. The determined correction values will be saved
internally.
The instrument must have achieved operating
temperature (switched on for at least 20 min) and
all cables must be disconnected from the outputs
before the alignment procedure is started.
In order to start the self alignment please press MENU, go to
page 2 and press the softmenubutton Self alignment.
In the opening menu press Start. The alignment procedure will
take about 5-10 minutes in which each step as well as the overall
progress is displayed by a separate status bar. After successful
self alignment you will see an information window. To leave the
self alignment, please press Exit. You can interrupt the run-
ning process with the ABORT button (f.e. you have forgotten to
remove all signal lines from the inputs). In any case a new self
alignment shall be started afterwards.
