Default Clamp Meter Problem.

On Sat, 02 Jul 2011 14:27:52 -0500, brian whatcott rearranged some
electrons to say:

I've got a problem. A good problem.

Always wanted a clamp meter - but never wanted to pay the price. So when
the cheapie Chinese models came along, I bought one. A model DT3266E to
be precise.
2A~ 20A~ 200A~ coupla ohms scales and voltage scales with attached
leads.


Anyway, I knew in my head that cheapie clamp ons are only
good for AC - and that's what the range selecter said too.

But still, I bought a way expensive little lead acid battery for a Honda
Recon 4 wheel RV, and filled it with the acid provided then hooked it to
a charger.

I tried the clip on. It read 2.5 A initially. That seemed about right.
It tapered to 0.9 A in the next few hours. THAT seemed right.

Here's the problem: if it works on DC ( or maybe rough DC)
why is it marked for AC only?

You're assuming it works... are you sure that the DC values that were
read were anywhere close to being accurate?
