  • Page 26: Selecting A Sensor For Configuration

    3-1 Selecting a Sensor for Configuration If multiple Sensors are connected to a single Touch Finder or computer, you can select the Sensor that you want to set up. Press [Run]. This will enable setting the current Sensor into RUN Mode before selecting another Sensor.

  • Page 27: Adjusting Image Quality

    Do not force the screw if it does not rotate anymore. This will damage the Sensor. • Do not turn the focus adjustment knob with a force that is greater than 0.1 N·m. This may damage it.
  • Page 28 Important The exposure time will be longer for larger values. This may cause the image to blur if the object is moving fast. If the Sensor is used on a high-speed line, check that the images are not blurred under actual operating conditions.
  • Page 29 • When the measurement object is moving HDR Function The HDR function is used for objects that have a large difference between light and dark areas. For this kind of object, clear images cannot be achieved with the standard brightness setting. The HDR function combines several images of different brightnesses (exposure times) so that the resulting image has a lower degree of contrast and can be measured stably for the desired characteristic.
  • Page 30 Several images are taken with different shutter speeds and combined. If the object moves while the image is being taken, the image will become blurred. • Images with different brightnesses are combined, so the resulting image will have a lower degree of con- trast.
  • Page 31 If external lighting is used, the image may appear as having different colors than the actual object. If this is the case, adjust the white balance. If the lighting built in to the Sensor is used, the white balance is already adjusted. No setting is required in this case.

  • Page 32: Adjusting The Object Position

    A measurement is not performed properly if the object is not positioned inside this measurement region (e.g., the result will be NG even if the object is OK). In machines in which the position of the object varies for each image, stable measurements would be impossible. To cope this problem, the Position Compensation function aligns the whole image so that the object to be measured is moved exactly to the measurement region.
  • Page 33 Press [Teach]. Drag the rectangle to move it. Adjust the image so that the measurement object is in the center. Press [ ] – [Model region]. Move the rectangle so that the characteristic part for position compensation is inside it.
  • Page 34 The internal timing for taking an image can be set to be delayed in relation to the external trigger signal. This can be used to adjust the object position in the image, e.g., if an external trigger sensor is used. If the object position still varies in the image the Position Compensation function must also be used.
