Keys Description
0...9/abc Enters the corresponding numbers (in numeric input fields) or characters (character input
fields).
. Inserts a decimal point (numeric input fields) or dot (character input fields) at the cursor
position. Multiple decimal points are not allowed.
+/- Changes the sign of a numeric parameter. In the case of an alphanumeric parameter,
inserts a hyphen at the cursor position.
Unit keys Selects a unit and thus determine the absolute value, or changes the unit, i.e. trigger a
recalculation without changing the absolute value. The function depends on the time at
which the UNIT key is used during parameter entry (see
Chapter 4.4.5, "Working with Units
" , on page 102).
For unit-free values, the X1 key is equivalent to ENTER. It confirms the previous entry and
deactivates the input field.

*... # Enters special characters. Toggles through the available characters if the key is pressed
several times in a row.
A <-> a Toggles between uppercase and lowercase characters.

Value" , on page 100 ).
