SF30 Accelerated laser rangefinder
Product manual
8. The analog voltage interface
The analog interface on the main connector produces a linear voltage of between 0.00 V and 2.048 V that is proportional to the
measured distance. A distance reading of zero meters always produces a 0 V output.
Figure 7 :: Analog voltage connections
The “6: Analog range” selection changes the value in meters that equates to 2.048 V. This can be any value between 1 meter and 256
meters depending upon the requirements of the application.
The “7: Analog port output rate” setting allows the output rate of the analog port to be set to any value within the limits imposed by
the exposure time.

Description
6: Analog range
1 m … 256 m
Selects the maximum distance that produces 2.048 V on the analog
port. This value changes the scale of the analog output.
7: Analog port output rate
39 … 20010 readings / sec
Sets the rate at which the analog port is updated with distance
readings.
The maximum value is limited to the “2: Exposure time” setting.
