Gauging the Resonant Frequency

Objectives
Nickwinkle the Metro-Gnome wants you to place the Oscillating Frequency Scanners in such a way that when you stand amongst them, you are hit by five overlapping Oscillation fields. Return to him at Toshley's Station in the Blade's Edge Mountains after you have done so.
 * Singing crystal resonant frequency gauged
 * Oscillating Frequency Scanners (Provided)

Description
Take these scanners to the Singing Ridge. By dropping them in a pattern on the ground, you will create overlapping fields that will read the amplitude of the crystals. Stand amidst them in such a way that you're in five oscillation fields and I'll have the information that I need! Your scanners will even work with those that others drop. Oh, and it's likely that a rift will be formed! I have no idea what, if anything, will come out of it, but be prepared for the worst.

Reward
You will also receive:

Progress
Well, do you have the measurements from the singing crystals that I asked for?

Completion
Oh, this is extraordinary! I had no idea... it's almost as if those crystals are alive. I wonder if there's some sort of symbiotic relationship between them and the nether drakes? Thank you, thank you! You must accept a little something from my collection of odds and ends that I wouldn't be caught dead wearing. One of them might look good on you, though.

Gains
Upon completion of this quest you will gain:
 * 11650 XP (or at level 70)

Progression

 * 1) Crystal Clear
 * 2) Gauging the Resonant Frequency
