I can see the idea is that the unit is installed on each valve assembly while engine is idling, adjust valve, and move on to the next one. Both quick, and accurate. But I had a hell of a time trying to read that thing while it's bouncing up and down. Maybe I should have tried turning the idle RPM down super low, to the point of almost stalling. I think it was about 600

There's also two ways to set the barrel in the unit, by means of a pin. This decreases the spring tension quite a bit by extending it longer. I think the heavier tension setting seems to work a little better, but the unit also seems to want to rotate when engine is idling.
