Adjusting The Internal Resolution; Optimising The Exposure Time - Baumer OX200 Operating Manual

9.2.2

Adjusting the internal resolution

Adjusting the internal resolution allows you to adjust the number of pixels transferred by the
camera. While this affects the measurement rate positively, it lowers the resolution and must
therefore be adjusted individually to the application. For this process, proceed as follows:
Condition:
ð The Expert Mode is activated (see
Instruction:
a) In the menu, select the Parametrization | Global Parametrization mode.
b) In the Global Parameters window, proceed to Data Acquisition | Internal Resolution.
c) In the drop-down list next to Number of points in x, select the desired number of points
along the X axis that should be read out by the camera of the sensor.
d) In the drop-down list next to Binning in z, select whether points along the Z axis should be
added and read out by the camera as a combined point.
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) In the menu, select the Parametrization | Global Parametrization mode.
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 range.
