The software does opens up some quick interrogation of the inductor in a number of way, really like that. I'm impressed with the blue toriods though, it means (I hope) those big loads likely won't saturate the choke during their brief startup surges.

I had a couple of 200A block shunts, so it made sense to just use one on the quick made saturation tester. I also have some current sensors including the ones you use here, but I also have so called clip on current sensors, however these actually bolt together, found the better units quite stable and almost completely noise free.

I have 500A, 400A and 200A units, and a few 50A units monitoring each of the four Solar regulators. Currently 5 connected to my Solar monitor. I needed the 400A unit to Log the inverter DC input Load. It Constantly graphs in real time and saves each 20 minute segment to SD. So any glitch and I can, with a single screen touch, look at what happened at any point in time, the slightest transient is still captured.  

The 400A sensor was to capture the work shed machinery startup surges of 390A, 410A and 450A for some of the bigger units. Fortunately the batteries don't even blink, even so, you can see why I'm going from 25v to 50+V.
