Description
The flash delay specifies the time between the
application of a flash signal and the start of the
flash. The image acquisition is delayed by the set
value. This value is known and fixed for supported
lamps. For "Other" lamps, you enter the value in
μs here.
Note: Delayed start of flash for lamps with 12/24 V
strobe input
Due to the high trigger level and the rate of volt-
age rise, a higher value for the flash delay may be
necessary.
If a value that is too low is entered, the auto-
exposure function can malfunction, for example.
The maximum flash duration specifies the maxi-
mum time that a flash signal may last before the
lamp becomes damaged. This value is preset for
supported lamps. For "Other" lamps, you enter the
value in μs here.
The monitoring integrated in the reader ensures
that the lamp never flashes longer than specified
here.
The duty cycle is the ratio of flash duration to
cycle duration. It indicates how much load a lamp
can accept. A duty cycle of 5% means that, on
average, the lamp may be on for a maximum of
5% of the time and must be off for 95% of the
time.
Based on this value, the internal lamp monitoring
ensures that the connected lamp is not overload-
ed.
The wavelength information is required for docu-
mentation for verification tasks and is specified
here. If you have selected "Other" lamps, enter
the wavelength of the lamp you are using here.
The light color is required for documentation for
verification tasks and is specified here. If you
have selected "Other" lamps, enter the color of
the light of the lamp you are using here.
