Cartridge alignment channel balance measurements?


I'm curious as to how people go about measuring channel balance when adjusting your cartridge alignment? If you are performing measurements, what is your accuracy tolerances?

No one I know uses channel balance to adjust cartridge alignment.

"Channel balance" means the relative strength of one channel vs. the other. If that's what you meant, it's unclear to me that measuring channel balance would be useful for adjusting any cartridge setup parameter.

"Cartridge alignment" usually means the combination of a cartridge's position along the headshell slots ("Overhang") and its angle in the headshell slots when viewed from above ("Zenith Angle"). Neither of these parameters affects channel balance in any meaningful or useable way.

Gross changes in Antiskating can sometimes affect channel balance, but measuring channel balance would be an ineffective method for adjusting that IME.

Azimuth angle (the angle the stylus makes relative to vertical when viewed from the front) effects inter-channel crosstalk. Many people, including me, have measured that to adjust azimuth and it's an effective method. Azimuth may also effect channel balance, but using that measurement to adjust azimuth would be far less precise than measuring crosstalk.

The other major cartridge setup parameters, VTF and VTA/SRA have no effect on channel balance that I'm aware of.

Azimuth alignment is what I meant to say. I have been adjusting the azimuth adjustment on my headshell seeing the impact on channel balance using the various test tracks on the Hi-FiNews Analogue Test LP. Sorry for my confusion.
Stringreen, thank you for the tip on the search, I found what I was looking for in this thread:

Dougdeacon, how do you measure crosstalk?
James1969, as Shure once had a record and meter that allowed you to adjust the channel outputs by changing Azimuth, so Denon once had a meter that allowed you to minimize crosstalk. I think I remember that you could also get a Denon product that reduced crosstalk. I have had and sold all of these and rely on my ears.
I have been playing with this PureVinyl software in combination with using the HiFi-News test record. There is a real time Input Balance measurement that gives you a +/- 0.00 measurement. So this would be a differential offset of channel balance.

I would guess that to measure crosstalk, one would have to find a test track for left and a test track for right channels to see the bleed over onto the opposite channel? The idea is to have minimal bleed over into the disabled channel of the test track?
