Couple things to note: It works in both directions, the arrow just shows you where the positive direction is. Zeroing ist best done after attaching it to the conductor youre trying to measure, with no current going through it. If you zero it before clamping it on, you may get a slight error.
The current spike you measured at 14A actually overloaded the probe (the button flashed). You needed it set to the 100A range in that case. Good review though and I hope to buy one very soon! :)
When setting up the scope channel, must one really configure for "Current" for it to operate? Is there instead a volts/amp ratio of the probe that would be used to give the same result if you accounted for the ratio? Thus you would read a certain voltage, but you would then scale that into amps yourself. Of course the convenience of directly reading "Amps" is nice, but suppose you have a generic scope that only has "Volts" for the probe.

Nice review. Really enjoyed the educational demonstrations.
Please scope a motor phase on spool-up and spool-down (maybe on different ESC PWM-frequencies)!

A really instructing video.
