The most important format to store information for docu-

directories. Press Accept to confirm the location of the
target directory.
The FILE NAME can be changed or adjusted to the corres-
ponding setting (SCR is the default label).

and the type of compression. The quality of the various
formats is identical for the multimeter graphics. You can
choose from the following file formats in the soft menu
Format:
❙ BMP = Windows Bitmap Format
❙ PNG = Portable Network Graphic
Use the soft menu key COLOR MODE and the knob to
select between GRAYSCALE, COLOR and INVERTED. If
GRAYSCALE is selected, the colors are converted to gray
scales when the data is stored, if COLOR is selected, the
data is stored as it displays in the screen, and if INVERTED
is activated, data will be stored in color with a white back-
ground. If you press the key SAVE, the current screen will
be saved immediately to the selected storage location with
the selected name and format.
