The
range
parameter controls the power of light the infrared transmitter
emits per pulse. The quantity of light affects both the range and the sensitiv-
ity of the light barriers.
The "normal" working range is
distance
. With this setting a range of ap-
prox. 10 m between the light barrier and the reflector can be achieved. The
sensitivity is enough to photograph also small subjects like insects. With the
setting
sensitive
the light barrier can react to objects down to 0.5 mm.
When photographing of very small objects at working distances less
than 60 cm we recommend the use of 40 mm reflectors (not included
in the scope of delivery).

The
dwell time
determines the time an object must stay in the beam of
the light barrier to be considered interrupted.
Using this parameter, fast moving objects can be blanked out in favour of
slow ones.
For example, a longer res time can be used to prevent rain drops,
snowflakes or insects buzzing around from causing unwanted triggers
when photographing mammals.
Wherever a fast response time is important, this parameter should be
set to 0 (the default).
