Tektronix clamp on hall effect current meter with peak hold and then later did a check with a Tek digital storage scope and Tek ac current probe. The Peak hold IIRC will catch peaks on the order of a few milliseconds. Did the measurement with the scope just to verify the peak capability of the clamp on meter for future use.
My results were consistent with the micro air claims. I think The key is to follow the learning instructions exactly. It's best if let the system learn on a good stiff power source, like your home service on as big a line as you can get to minimize voltage drop during turn on. I used my 30A feed I had wired in the house for the trailer.
Nice! When you commented earlier about watching the startup/inrush for a few seconds I figured you were probably using a scope. That is just amazing the Micro Air dropped the inrush from 50a to 20a! My readings showed less of a drop, but I was using an inrush capable clamp-on---not nearly as accurate. Concur with following Micro Air's learning instructions closely---especially if you're pushing the envelope with a 13.5 or 15k unit with a high LRA (60a++). IMO it could potentially mean the difference between success or failure with an EU2000i. Hopefully less of an issue with the EU2200i.
