They are incredibly useful for other things too.

Yeah, I read though the list and looked at the pictures of them in
use.

they not only show if one is working or not but give the pinout and
type.

That is clever (well, if not actually clever, very handy). ;-)

It's clever to me as I have no idea how they do it. ;-)

Saves having to look it up.

Good point. So, say I had an IR sensor device with 4 pins (2 pins = IR
LED and 2 pins = photo transistor), could I just plug all 4 pins in
and press go and it work out one or both of the connected devices? Or
would you typically just use pairs of pins and see what it comes up
with?

An optocouple? Don't think it would test one of those in one go.

What would it think of a photo transistor (a transistor with no
'base')?

Dunno either - it should say in the spec what it will and won't test.

Hopefully I'll be able to find out for myself soon. ;-)

At under a tenner I'd guess you'll be well chuffed. ;-)
