2.6.2.5 Data exposure via keyboard
The data for the Keyboard and Keyboard-Scale formats cannot be entered via the control console.
Data input for these formats is through an external keyboard (UK English type), which connects to the
socket marked "Keyboard" at the rear of the control console via a Mini-DIN connector.
The following characters can be entered through the keyboard:
Letters: a - z and A - Z
Numerals: 0 - 9
Signs: - + _ * = [ ] ; , . / ! @ ? $ % & ( ) { } : “ < > ? ’ # |
The various digits can be selected, corrected, deleted or confirmed with the keyboard's control keys:
Space bar, Cursor , Cursor , Backspace , Enter and Delete.
Conclude selection of the data format by pressing again the <PICTURE> or <BRIDGE> button on the
exposure control console. The “PIC” or “BRI” symbol, respectively, in the display window will then
stop blinking.
(1) Keyboard data format
Each of the 8 digits of this data format can
individually be occupied by alphanumeric,
grammatical or mathematical characters/signs,
or spaces.
Example:
A test specimen may be marked “TEST -
3/9”.
(2) Keyboard-Scale data format
This data format is intended for the exposure of
a scaling bar. The digits 1, 6, 7 and 8 of the
data exposure field are occupied by the left and
right limits of the scaling bar and the "µm" unit
(see the illustration). At the 4 digits in between
you can enter the length L covered by the
scaling bar in the specimen plane. The first free
digits can be filled with "-" or "0" characters if
the length value only comprises 2 or 3 digits.
