Further information
When you select a vertical softkey, you are selecting a channel
and potentially an NC as well.
Channels that are configured in the channel menu, but defined
as a channel gap in the corresponding NC, will not be
displayed.
Precondition:
The cursor is positioned on an input field or input/output field.
You can switch to Pocket calculator mode with the equals key.
If you enter a basic arithmetic symbol (+, –, /, *) followed by a value
(e.g. 13.5) in this mode and
and then press the input key, the next value to be entered is
calculated with the previous value.
If the input/output field is opened with the input or equals key, the
editor is in insert mode; if the field is opened directly with a character,
the editor is in write-over mode.
Help display
If pocket calculator mode is active, you can call a help display which
explains how to operate the input editor by pressing the Info key.
Function
The letter "F" ("f") is used to identify a fit. The letter is followed by the
diameter/length specification. This is followed by the tolerance class
and the tolerance quality identifier.
The arithmetic mean is calculated from the upper and lower limiting
value and displayed in the field.
