As a repairer of electronics goods this would be very
handy. Yes, I can use a multimeter but it would be nice to
see beta and Vce sat in the same test, as I have boxes of
older transistors etc that I often use for hobby or
prototyping.

In-circuit testing is great, my good Fluke 12 (favorite of
repairmen) does great in-circuit testing of diode junctions.

Also it should have three terminal "pads" on top, so if
you have a big box of parts you could just press each one
on to the pads and read type, beta, sat, etc. Surely this
would be handy?? :o)
