So this was what was in the mystery Newark box that I was waiting for:

Fluke shrouded banana plug socket to male BNC adapters, extension leads and a set of Pomona test leads. I thought about ordering regular Fluke test leads to replace the set missing from the 27 kit but decided a full Pomona set with the pouch might be a better idea.
With that in place, now I can get on with testing what I wanted to evaluate:

The Fluke current probe was a pawn shop find and the OTC was a Kijiji pickup. First set of tests is into a multimeter on the mVAC range to see if they're working and giving plausible values. They're into the X10 side of a line splitter with a 100W lightbulb as test load, bench lighting, and cold basement heat source.

Given the voltages and currents observed and taking into consideration these clamps are both being operated pretty much right at the bottom of their working ranges, the values which work out to a touch over 100W look reasonable for that lightbulb. Now the next test was to see if it was possible to observe AC current waveforms with these clamps and that's where the Fluke adapters came in:

Fluke shows a nice clean trace on the Agilent.

The Fluke Scopemeter hits it out of the park compared to the Agilent though because you can define the probe as almost anything. I've got it set up as a 10 mV/A current probe to take into account sitting in the X10 slot on the line splitter. What I don't like is the trace thickness on the Scopemeter. If it was a CRT scope, I'd be reaching for the focus control to tighten the trace up.
Up next is the OTC which was kind of disappointing:

The noise doesn't appear to affect measured values all that much but it sure is ugly when viewing the output graphically instead of numerically on a DMM. It'll be interesting to see how it performs on direct current and at higher current values instead of loafing along at a bit less than an amp. I did try toggling between the 200 and 2,000 amp ranges on the OTC to see if that made any difference but the output was unchanged.
As for the two portable scopes, I wish you could get it all in one place. The Fluke's functionality combined with the Agilent's trace sharpness would be fantastic.
