Is it possible to measure the output of a pickup by attaching a meter to the output cable? I'm trying to balance the output volume of the strings. I've been turning the adjustment screws and that helps, but I thought there might be a away to actually get a measurement instead of just using my ear. (ps no jokes about how do you get your ear in that little screw slot!!! )

The best way to do this is to use an oscilloscope.
Simply take a non powered line level output signal from your amp and connect it to the input of the scope. You will easily see the amplitude of each plucked string. You can then adjust the pick up height as necessary. Remember that there is a point of diminishing returns when the pick up gets too close to the strings. The strength of the magnet will stop the string from vibrating.
If you can't do the scope thing, you can connect your guitar to any piece of recording equipment that visually shows the input level. Use this as a reference to balance the pick up.
The best place to start with the string height is the manufactures recommendation. They do a lifetime of research on this subject and always post the optimal settings for their pick ups.

If you run the signal into your computer's sound card, you can probably see the levels there. Record it for meticulous scrutiny.

Thanks for your responses. Since I am using a laptop, I don't have access to the sound card. But I do have access to a scope. Never thought of that. I play C6th lap steel and my High E and Low C strings seem to blair out. I know part of the problem is my technique, but I'm sure that balancing their output will also help!

You could probably use Audacity to record it, and examine the levels later.
