[MRCA] Technoweenie Stocking Stuffer

[Gene Smar]

How about inserting a short jumper wire between the two input contacts, install the BFC, then remove the jumper?  In any case the price is cheap enough that I'll get one just to mess with it and find out the true values of some of my RF chokes.  Thanks for the heads-up, guys.

Hi Breck,

I agree. I blew up a similar device while working on a power supply. The
test leads are connected directly to the microprocessor. There was one
version that had a relay that shorted the inputs before you make a test to
make sure this doesn't happen.
