Chapter 4: Operation PR4000F
20
It is recommended to deactivate the entry into the setup (see figure 4) after all parameters have
been edited. This allows quick switching through the 1 to 4 operational displays in a circular mode
without stepping through all setup dialogs.
By pressing the escape key (ESC) one time it is easily possible to switch the unit back to the
display #1 from any position in any level.
4.2 Editor
The PR4000 is operated and configured by dialogs (two-line LCD) or digital I/O (RS232/RS485).
The dialogs are organized in a simple table hierarchy. All the dialogs can be accessed and
displayed easily: you can change from one dialog to another using the up/down arrow keys or
return to the main dialog at any time by pressing the ESC key. The dialog table is divided in two
parts, an operation and a setup part.
Switching on Edit mode
Edit mode can be switched on or off in the dialogs. You can enter numeric values in Edit mode,
alter variables, etc. There are two ways of switching on Edit mode:
1. With the ENTER key
2. With the left/right arrow keys or
3. When you switch on Edit mode, the cursor appears as a flashing underscore below the first or
last alphanumeric character. You can move the cursor within a line using the left/right arrow
keys or change the preset values with the up/down arrow keys.
If '9' is displayed and you press the up/down arrow keys again to scroll the number, the display
automatically creates two digits ('10'); the same applies analogously in the opposite direction.
If, when you exit Edit mode by pressing the ENTER key, the value you have set is outside the valid
range, the highest or lowest permitted value is stored instead.
Switching off Edit mode
You can switch off Edit mode again by pressing the ENTER key. The entered values are not stored
until you press the ENTER key.
You can also exit Edit mode with the ESC key. In this case, however, the values are not stored.
Decimal point
You can mark the decimal point in this dialog with the left/right arrow keys and shift it with the
up/down keys. The up arrow shifts the cursor to the left, while the down arrow shifts it to the right.
The new decimal point setting takes effect in all the dialogs in which measured values or values
directly referred to them are displayed. It does not affect device parameters, such as
Gain .
