M C8
Depends
on
model
Unit 1ms. Sets the minimum time between two
triggers. No trigger can be generated within
this time.
LS knee point P 3A 58
Sets the point where the lightsensor/ADC curve
changes from first slope to second slope.
LS multiply 2 factor Q 03 03
Multiply factor for second slope. This factor is
multiplied by first slope to give second slope.
LS subtract value T 96 150
Offset for lightsensor/ADC curve. Below this
ADC value the light sensor value is zero.
Number of high

X 06 06
Minimum number of successive 200μs samples
of no reflected signal before a trigger is
generated
Number of low
samples
Y 10 16
Minimum number of successive 200 μs samples
of no reflected signal before X
