Step by Step How to Use a Digital Multimeter / Oscilloscope for Azimuth Adjustments

Excellent info provided!

FWIW, it is advisable to use the same preamplifier channel for measuring the crosstalk levels of both channels in order to minimize electrical errors. Unfortunately this requires swapping Input channels between the testing of R/L tracks.

Also, most digital level measuring devices utilize a sample hold function. It is highly advisable to use this “Hold” feature as it allows for dismissal of artifacts by observing ONLY the low capture and tossing out Average & High level readings.

As stated, the objective is to obtain as low and as equal crosstalk levels as possible between channels by rotating azimuth. Pay attention to anti-skating & pray for symmetrical channel separation of your pickup’s coils.

If all else fails, adjust by ear for minimum sibilance while enjoying increased resolution.

You guys seem to understand there are two different ways of setting azimuth. What you are missing is what this means: The sort of absolutely precise azimuth you are after cannot be achieved via any sort of observation other than listening.

The two methods everyone uses are

1) Observing the angle of the stylus in the groove. This is what the vast majority recommend. Get a USB microscope.

This is indeed great and wonderful for getting your stylus geometrically aligned for tracing the groove - of a static, stationary LP. The stylus sticks out from the end of the cantilever. Playing a record exerts lateral forces that torque the cantilever. Everything from the stylus to the cantilever to the cartridge body to the head shell and on down the line starts oscillating like crazy. If you could see it in high speed slo-mo you would freak. You would also shake your head at the futility of observing the static state.

and

2) Observing generator voltages. This is the electrical observation you are asking about. In this one, which I would by the way say is arguably more relevant, the observation is to get a voltage as ideal as possible.

The problem with this one, it is like measuring an amp by watts. Do the most watts mean the amp sounds the best? Right. Waste of time.

This one will at least give you a fighting chance of getting really good separation, which will probably lead to a bigger wider deeper sound stage.

Probably. But no way to know for sure. Why? Because of #1. What if the electrically correct azimuth results in a slightly different stylus azimuth? What then? Which one do we use? Split the diff?

No. We listen. Listening is the only observation that sums all these and more into one coherent whole. Same for VTA, VTF, and all the other stuff too by the way. Just every once in a while instead of just saying so it is nice to let the folks know I know all this tech stuff too. Before you discard something it is always best to know exactly what it is and why it is okay to discard it.

obviously the OP is in an excellent position to do both and discern …..and learn

So lewm, regarding your response, I have in my hands the Acoustic Sounds test LP already so I can do the stereo, left and right channel 1K hertz test tones.
In your post you said, " Also, keep in mind the obvious fact that you would like to insert your meter or scope as close to the cartridge output as possible. If you readout at the phono stage outputs, then you are including any inequalities between the two channels of your phono stage in the data. On the other hand, trying to read the microscopic voltages from an LOMC cartridge directly can be frustrating or impossible if you want repeatable results. It's easy with high output cartridges and good instruments."
Based on this, with my Hantek, I'm wanting to use it in the oscilloscope or digital multimeter mode?   I dont know if it is sensitive enough to read out the turntable directly or not.   My cartridge is the Soundsmith Zephyr II which is a low compliance, high output cartridge.  Output on the spec sheet is output voltage of > 2.2 mV @ 5/cm/sec.
This is where I'm technically inept as far as knowing if that is enough for this Hantek to read out at the turntable or not.  I'm guessing it wont go low enough as it says, " VOLTS/DIV Range: 10mV/div~10V/divat input BNC ".   This is 2.2mV output so lets assume I have to measure out of the Sutherland 20/20 outputs instead to get readings. 

Deja vu all over again.
