Dave,


Did you get any instructions with yours?


No - just followed those on the Ebay ad.

Seems to basically work but I've noticed that repeated testing of a
capacitor seems to give either
esr = 0
esr = 0?
esr = 0.4
Are certain pins better for certain tests/components?


I found the actual test lead sockets didn't do anything much. So only used
the small sockets alongside them.

It did not seem to identify the pins on a N channel J fet (2n3189)
correctly. I could fit it flat towards display and flat away from the
display and the pin out displayed was the same.
Seems to draw 1uA when off which is pretty good too.
Just got to make/find a box for it.


It worked on an IRFIZ34 here - not tried it on any others.

Be interested to find out how you end up boxing it up.
