Set Infinity
The Holga was 60mm, the Diana is 75mm. So you need to set the new assembly 75mm away from the film plane. As long as you didn't open the circle too wide, the lens should snugly fit and allow you to adjust it and stay put.
The Diana can change from infinity to a couple of feet by turning the black dial on the front. Make sure its turned to infinity before moving on.
Moving the lens back and forth changes the focal length of your camera. When it is in the proper position, the focal distances on the front of the lens will actually work.
Grab yourself a tripod and some ground glass within an empty film pack. If you don't have any ground glass a piece of tracing paper taped inside will work just fine, just make sure its flat and not wavy.
Attach the lens assembly to the camera temporarily, we can now set the lens for infinity.
