Baumer OX100 - Optimising the Exposure Time; Adjusting the Laser Power

9.2.3 Optimising the exposure time
The colour and surface of the object influence the amount of reflected light. Dark objects require
a longer exposure time than bright objects to obtain the same signal strength. The sensor offers
the Optimize function for a one-time automatic adjustment of the exposure time. With this func-
tion, the sensor determines the optimal exposure time based on the light quantity reflected back
from the object. The adjustment involves the entire visible camera image. A reduction of the
measuring rate can occur with long exposure times.
To initiate the automatic adjustment of the exposure time, proceed as follows:
Instruction:
a) Select mode Parametrization | Global Parametrization in the menu.
b) In the Global Parameters window, proceed to Data Acquisition | Exposure Time.
c) Place the object to be measured in the field of view of the sensor.
d) Click the Optimize button.
Result:
ü The sensor automatically adjusts the exposure time (once).
INFO
In Expert Mode, you have the additional option of manually adjusting the exposure time in the
entire area.
9.2.4 Adjusting the laser power
With highly reflective, very light or very dark objects, it may be necessary to adjust the laser
power. Only change the laser power if you cannot sufficiently adjust the intensity by optimising
the exposure time (Optimising the exposure time [}44]). The general rule is:
n
Very light objects: low laser power
n
Very dark objects: high laser power
To adjust the laser power, proceed as follows:
Condition:
ð The Expert Mode is activated (see Header [}34]).
Instruction:
a) Select mode Parametrization | Global Parametrization in the menu.
b) In the Global Parameters window, proceed to Data Acquisition | Laser Power Selection.
c) In the drop-down list next to Laser Power Level, select the desired level of the laser power.
