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....

The Fozgometer ostensibly could be replaced with a decent oscilloscope, so what is it’s benefit to someone who already owns a couple of high-end oscilloscopes? Don’t take my question as being combative, I’m just curious if the Fozgometer has any unique qualities that lend it to being better or easier to use for the task. 
AnalogMagik looks intriguing but having to spend $750 plus another $75 plus tax, and no support unless you buy a “$150 Lenovo” from them seems extremely suspicious. You simply cannot get a usable laptop for $150. Their literature is written by someone who is borderline illiterate, which also seems their product seem as genuine as an email from a Nigerian “prince” who has millions of dollars for you. 
I have a few test records in my collection, so I’ll have to check if any have the single channel 1kHz tones. I couldn’t imagine not having at least one good oscilloscope. For a long time it was a 20mHz Philips 2 channel with CRT, but I have a Tek 100mHz 2 channel with LCD screen also now.  Also have 2 Technics TPBGA003 headshells on order (C$120 each from Panasonic through my Technics / Panasonic dealer) that have the azimuth adjustment feature. The guy there tried to convince me that everything from the cartridge and turntable factories is already optimally aligned, but I want that extra degree of certainty.
