Main display
The main display consists of three lines with
Process Values. Each line is user definable
with the restriction that each line should have
a different Process Value. The default settings
can be defined here. By pressing one of the
two smaller process values, this will become
the main process value in the main screen.
Autoreturn will cause the main display to go to
default setting.

main and secondary display lines are
determined by the choices made in
the menu measurement

Additional text
Each process value can be given an additional
text containing up to 12 characters per text.
This text is displayed on the main display next
to the process value. This way the user can
distinguish separate measurements.
X-axis timing
The time range of the trend graph can be set
from 15 minutes up to 14 days.
Y-axis limits
The ranges for each measurement need to be
set according the application.
Auto return
When Auto return is enabled, the converter
reverts to the measuring mode (main display)
from anywhere in the configuration menus,
when no button is pressed during the set time
interval of 10 minutes. The HOLD flag will be
cleared and all outputs will function normally.
