What is the Best Tool to Measure Cartridge Azimuth?

What do you use to measure / set azimuth of your cartridges and / or styli? I am afflicted with diminished eyesight, so aligning the azimuth of the stylus by eye is not practical.

To that end, I’ve use a simple bubble level (spirit level) about 1-1/2” in diameter to get the headshell as close to level as possible, after first leveling the platter by adjusting the turntable feet. 

I figure some clever lever engineer has made an easy to use electronic tool for this purpose, but I haven’t found anything in my searches. Nature abhors a vacuum, so one day if not already, it might surface. 

Until then, does anyone have alternate methods? How about using a test record? Is that feasible? I do have a couple of good oscilloscopes by the way, so I can make precise measurements of levels, phasing, frequency, etc....

For those who are using a mirror make sure you have one that is slivered on the same surface as you rest the stylus, or you will set it wrong.
I'm not sure why you say that. Actually, the further the silvered surface is from where the stylus sits, the more apparent any deviation from level will be. That makes it easier to set accurate azimuth, and some stylus gauges are intentionally designed just that way, such as the terrific Wallytractor. But you can set accurate azimuth either way.
