I used to use an Analite many years ago. IIRC it had two small lamps (one for power on, one for the light adjustment), a small sensor window, and a large dial.
Make a perfect print using your usual technique. Leaving the enlarger settings the same, turn on the Analite and place the sensor on a highlight area you wish to retain some detail in (Zone VIII.) First turn the dial until both lamps are on, then slowly turn it back until one of the lamps goes out. Record your exposure time and note the number on the dial, this number will be used for future prints with this paper and developer combination. To set the enlarger for another negative, place the sensor on another highlight area similar to the one you set the Analite for, with the dial at the previously determined number. Starting with the lens wide open, slowly close the aperture of the lens until the lamp goes out. Expose the paper for the previously determined exposure time, and the highlight on the paper should turn out the same as your reference print. That's it.
I never used it with VC papers, so I don't know what effect VC filtration would have on it. Hope this helps.
