Bart & list,

I have had trouble with hair dryers as loads, because the motors are usually
"universal" types with brushes that put out a lot of electrical "hash".  In
my case, the impulses messed up my readings with a digital multimeter.  So I
recommend using electric frying pans filled with water, with the temp
control set above the point where the pan cycles on and off, e.g. 350
degrees F.  This makes a very good electrically quiet load.

Hi Gary, All,

I meant to say "concurrent" readings (happening at the same time), not
concentric. Sorry about that. Looks like I need to fix that. The point
is to view both V and I at the same time. The values can bob up and
down, so using a single meter is "not" very accurate. Accuracy with this
method requires 2 meters side by side. Using a hairdryer for the ballast
is my recommendation. It's been the best load that has the least
fluctuation in my experience. Just let the hairdryer heat up and the air
does a great job to stabilize the load. This method works great and was
first described to me by Terry Fritz. I've done it with and without the
RC network (it's not needed).

Take care,
Bart
