6.5.1
Reading mode (standard operating mode)
The CLV performs a self-test after it has been switched on. It switches to Reading mode
("Device Ready" LED lights up). In the default setting the "Sensor" switching input is the (ex-
ternal) trigger source of the reading pulse. The reading result is output by the CLV at the end
of the reading pulse via the host interface (default setting) and terminal interface.
The reading result of the terminal interface can be displayed in the CLV-Setup Terminal
Emulator. The CLV terminal interface must be set to the R
EADING
D
IAGNOSIS
mode for this pur-
pose. This mode is selected for the default setting. The reading result of the terminal inter-
face has a fixed, invariable format.
The Reading mode can be called up by choosing V
IEW
in the menu bar or via the Terminal
Emulator.
Line scanner with oscillating mirror:
In the Reading mode the CLV deflects (by default) the scan line about the position CW = 50
at a frequency of 1 Hz and a maximum angle of
±
20
°
. 50 CW corresponds to an angle of
deflection of 105
°
