Aha! You're right, it says 7.2. My original estimate was very crude, and everything else on the meter was powers of 10... well never mind. > ... > Assuming you have a regular meter like mine, the calculation should yield > 810W - 576W = 234W, which could be reasonable.

Also note that if my first reading was 1 second lower then we would compute 260W, not 234W -- so we're well within experimental error. > Beware of > "hidden loads" too... a refrigerator kicking off or on toward the end of > your measurement interval can reduce or increase respectively your > apparent load. Yup, I had unplugged the fridge. Anyway, this was EXACTLY the kind of help I was looking for. Jeff, it's because of people like you that LUGOD rocks!
