Operation

How to operate the EC 900

The EC 900 can be operated by using the keys of the device or via the Dialog 900 read-out and pa-
rameterization program. While you can display and change only the most important parameters by
using the keys of the device, you can view all parameters which can be read or changed if you use
the Dialog 900 program.

Structural design

The data structure of the device can be thought of as a series of books with chapters, paragraphs
and lines.
Available keys: „ ", „ ", „ ", „ ", „Enter", „Esc".
Book 1
information line
book
chapter
paragraph(s)
line(s)
<book1 book2 book3>
if required, actual information is placed in the first line of the display. If there are no events, the first
line is empty. The lines 2 to 6 contain, depending on the level in which one moves within the struc-
ture shown above, chapters, paragraphs or lines. In 7th line of the display the books are shown,
where the current book is always placed at the beginning of the line. The next possible "books" are
placed on the right of it. The arrows "<" and ">" at the beginning and end of the 7th line indicate
that more "books" are available and can be reached via the buttons " " and " ". Within chapters,
paragraphs and lines the single screen lines can be accessed using by " " and " " keys. If more con-
tent lines are available than screen lines, all higher rows are shifted one line up when the last line at
the bottom of display is reached.
For example the device has a book "PTZ," which in turn contains the chapters "p" for pressure, "t"
for temperature, "C" for conversion factor, "K" for compressibility factor and "SC" for supercom-
pressibility. If a "+" (plus) sign stands before the symbol, this means that further scrolling in this
"chapter" is possible. With "+p" for example you are forwarded after pressing the "Enter" button to
the paragraphs "Measured values", "Limits", "Default values", "Parameters" and "Modes of opera-
tion". Again, a "+" (plus) - character before the paragraph, e.g. "+Limits", points out that more lines
are found under this paragraph which also are accessed by pressing the "Enter" key. In this case
