So you have to get an RMS reading.
You would be surprised just how far off the numbers will be. >100%

I know this too well, because I went down that same road my first time too.
It was horrible.
Down right embarrassing actually, since the customer saw it too.

I trust you.

I just wanted to double check myself. I am just playing around now with the min/max on an 85w bulb and just this 85w bulb gives me a bad reading. I get for MAX 132 and MIN is 124 so it's a little off if I run this through the calculation you provided me I get
(132 - 127 ) * 196 / 66 = 1.48
(127 - 124 ) * 196 / 66 = .89
Even avergaing these 2 I come up with 1.18 that is that is double what the clamp meter is telling me is .66 which I tend to believe now because since it truly should be .7 the fact the clamp is telling me .66 and how can I really tell if this bulb is putting off truly 85w.

Here is something I am seeing that is strange. If I plug the 1600w hairdryer that has 2 settings I get 2 readings as you would expect on low I get 152 MAX and 103 MIN then for the high setting I get 179 MAX and 76 MIN but when I plug in the 10 amp hot air gun which also has 2 settings when I set it on low I get 172 MAX and 127 MIN with the reading I get from the hair dryer I would have expected the min reading on the hot air gun to go to 82 that is goofy why would the hot air gun get such a different result then the hair dryer?

The LTC is on it's way I found those at digikey looking for the little board for it now. Also getting the TLV324 would it be to much trouble to get a look at how you wired that up with both components to the pic?
Thanks
