ESR meter.
 

One quite useful feature is you connect a transistor any old how, and it
tells you which pin is what (pinout), PNP or NPN.

Dave,

Did you get any instructions with yours?

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?

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.

No - just followed those on the Ebay ad.

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

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

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

I've just ordered one of these boxes ebay item 271115299166

The module will just fit across the smaller dimension of the lid
allowing some panel space for connector and the battery.
I will stack up some SIL turned pin sockets to bring the 5 way connector
up to the lid surface and in parallel, add some 4mm sockets for test
leads/probes.
A little perspex light pipe for the led and anther piece of plastic to
operate the push button.
Screws and nuts for spacers for each board to secure everything to the
lid. Something yet to be invented to hold the battery in place.
I might add a on/off switch as I dont envisage using this a lot so
knowing my luck the battery will be flat each time I come to use it.
