Metrohm 838 Advanced Sample Processor, Operation 11
2.1.4 Instrument dialog
The instrument dialog of the Advanced Sample Processors is arranged
in menu levels in which the following rules apply:
Main menu
The <CONFIG>, <PARAM> and <USER METHOD> keys of the
Sample Processor open a main menu whose thematically arranged
submenus are accessed by repeatedly pressing this key or with < >.
The name of the main menu appears in the first line.
Submenu
Each submenu has its own title which is indicated by " > " and appears
in the lower line of the display. From the title you can use <ENTER> to
access the individual questions with which the most important instru-
ment settings can be altered. The first line of the display always shows
the name of the active submenu.
Navigation in the menus is by the cursor keys; with <HOME> you can
access the first line of the menu and with <END> the last one.
<QUIT> exits the active menu and accesses either the next superior
menu or the normal operating condition.
<ENTER> always opens a submenu or confirms the data input of the
lowest menu level.
Input lines
For input lines without " : " the values can be entered by the numerical
keys. The set value is accepted with <ENTER> and the next line ap-
pears.
For input lines with
" : " predefined values can be selected with the
<SELECT> key. <ENTER> accepts the set value and the next line
appears.
Depending on the parameter, <CLEAR> is used to set the initial value.
The <CLEAR> key is also used to reject incorrectly entered values.
<QUIT> exits the questions and returns to the submenu.
