    Hi! Loving my Dual CS 620Q. But with the fully automatic tonearm, I'm not able to drop the stylus with the turnatable powered off, making it impossible to, for instance, measure the stylus pressure or the cartridge alignment. Any suggestions about how to do this would be welcome. Thanks!

    Unplug it first.

    Edit - misread the OP, apologies for a non-helpful post.

    Or perhaps unplug it while a record is playing, so the arm is already down.

    I don't personally know the 620Q, but I've had this issue with other TT's.
    You should be able to remove the platter (https://www.vinylengine.com/library/dual/cs-620q.shtml).

    Once removed, you may need to use something to bring up the level of your scale, like the scale's plactic cover or a CD jewel case, to the correct platter height.
    You can then check your tracking force and compare it with the tracking force gauge on the arm.
    If it's right on, no need to question it again.

    As far as alignment, the manual on VinylEngine.com shows a templet you can cut out but that may be difficult from a downloaded copy.
    It does give overhang and effective length, though.

    My Sony PS-X7 parks the tonearm in the up position when the record is not being played. @jrtrent is correct. Put on a record, start the player so that the stylus drops on the record and starts to play, then pull the AC plug to remove the power. At the same time, stop the platter from rotating. This should free the arm so that you can align it with what ever protractor you have and be able to use a digital (or other) scale to set the VTF.
