Looks like the display needs work, though. All discrete TTL so no biggie.

Interesting but I read these devices use special cells as a reference. Are these potential maintenance problems?

There are small lies, big lies and then there is what is on the screen of your oscilloscope.

I believe they use a zener diode. There's a sticker on the inside which has the reference voltage of it.

EDIT: It just sold. I'm wondering if it has the 1KV option?
