Very straight forward, calibrate it after installing the software and have a trustworthy measure ready for your piston diameter measurement and a solid weight with known exact mass for delta mass tests for Vas. click Q, Fs test, when its dome click Vas test and enter info, add mass to cone, click okay and it'll do its thing and youre done. You can download updats from the site as they are published.

If the woofer is bumped during test, it will record it and I recommend starting the test again. I set my start point to 10Hz and my end at 2K, but 500 is usually plenty.

yep, I use 150g mass, just needs to be solid so that is doesn't change mass while vibrating (as a fluid would do) I have used my cell phone before lol. I use an accurate .01g digital scale and weigh out my mass and presto!

Yep! unbelieveably handy, test any driver, use it to model impedance rise and fs shift in an enclosure etc, even plot impedance curves and box responses, excellent tool! I know you'll love it.
