Rated 4 out of 5 by from Excellent value, works well The device is a little boxy and feels cheap - but this is a very cheap logic probe! Works at TTL or CMOS levels and the 'pulse/mem' button is basically a latch to catch fleeting 'pulse' signals. The packaging actually describes two different devices, which is confusing, this is just a simple logic probe that would have cost a fortune years ago. For anyone unsure what a logic probe is for, it's for anyone interested in digital electronics wanting to check an active circuit board to see whether pins are in the logic states of zero, one or pulsing (ie have data). Far faster than hooking up a logic analyser, and far more reliable for the most part. If you need to see signal timing, you need an analyser or good oscilloscope, but with a schematic and a knowledge of gates, you can debug easily 80% of problems with this alone. Often old TTL chips will get stuck gates (for instance in old video games), causing strange problems, this can help you track down dodgy chips to replace.

Could you please tell me what the socket on the side of the probe is for? Thank you
