CaptAL, I would be interested in what you found in these computer labs.
I have asked a question along this line before on another forum.
The subject comes up from time to time, but in my experience I have only been able to isolate two specific instances where additive Harmonics was indeed a factor in any failure of equipment.
As far as the Fluke 43B, we also own one (or did until recently when it seems someone may have stolen it,

) but it is an intirely different animal (at a much larger price) than the Sure Test 61-156.
I had a brochure on my desk a while back for a power quality, graphing, logging, bring you coffee, sing happy birthday, with optional software it will lap dance, etc... meter

in excess off $14,000.00. (we will not be buying one

)
The bottom line is, the Sure Test 61-156 for an under $700.00 meter (with current probe) that does what it does it is a pretty good meter.
