Resistors are 1/2 Watt except for 1 Watt 1K resistor. Connections on right are for Oscilloscope top (vertical) bottom (horizontal). Left connection to capacitor is red test probe and right connection is black test probe. Adjust components or group of components to see "signature" wave forms.

Shit! I can't believe it. I used a test box just like this one, for 35 or more years. It was one of the handiest tools in my kit. I was always using it. Over time I modified it to have two voltage & three current ranges to use, depending upon what type and size of component I was checking. It was initially for testing diodes and transistors. I realized by varying voltage & current I could also check zener diodes, some capacitors and a few inductors. About 2 days ago, I remembered this device and figured that even though it was SO simple, I would draw it up (from memory) and post it on EC. I waited one day too long. YOU BEAT ME TO IT! A little device so obscure, that I haven't seen it repeated in nearly 40 years. And in the space of two days...we both come up with virtually the exact same device. The poor man's curve tracer.
