It is necessary to calibrate a zoom encoder DALS systems only first time. Then the DALS software and its updates will use the config file with saved calibration (%PROGRAMDATA%\OctoNus Software\Digital Microscope\zoom_encoder_calibration.xml).

  1. Start the DALS program and connect to the microscope.
  2. Select the "Tools" tab. Find the "Zoom encoder calibration" panel":
  3. Do next steps for all ticks on the zoom wheel:
    1. Manually change zoom wheel to next tick (for example 6.0). You can see that the 'angle' label is changed.
    2. Change zoom value editbox to the correspondent zoom (for example, 6.0 again).
    3. Click at the  button. You should see that a zoom-angle pair is added to the table:
  4. After you add pairs for all your zoom ticks you'll see the zoom-angle table like this:
  5. Go to the 'Hardware' tab and check zoom calibration by wheeling the zoom wheel manually and compare ticks with zoom value in the DALS GUI:
