Trigger Length
Note: In the case of speed measurement, the
minimum length of the trigger is defined by the
time of speed calculation.
In the same mode setting Trigger Length = 255
keeps the trigger active until vehicle has
passed the measurement point.

Speed Pulse Rate
Speed pulse rate is in use after detection of a
vehicle in speed measurement application (or
mode). Speeder X1 is class 1 laser product.
Eye-safety standard limits the pulse rate of
Speeder X1 to 2000 Hz for pulse trains in short
range (Condition 2, target distance less than 2
meters). Laser pulsing exceeding 2000 Hz is
allowed only while measured distance is more
than 2 meters. Pulse train limitations are
controlled programmatically to fulfil the
Standard EN 60825-1:2007 (IEC 60825-
1:2007) Condition 2.
