I bought an NSL-32 from smallbear, and something doesn't quite FEEL right.
1. The short leads are the LED, right?
2. The dot indicates the cathode (-)?
3. What resistance should I get when it's on? Off?

Datasheet tells us that on resistance is maximum of 500 ohms and off resistance is minimum of 500 kilo-ohms: http://www.farnell.com/datasheets/16352.pdf
Thanks, man. I just wanted to make sure.
I'm not getting any resistance reading with it off. I'll try it again. With it on, I do get 0.5 kOhms (thanks, DMM for fun decimal times).
Put a resistor and another LED in series with a battery to check, or use you rmultimeter's diode setting.

Remember its just minimum resistance of 500k. The datasheet doesn't provide any information about tolerance, so it can probably be a lot higher. Does your DMM have automatic range? If its manual start with the highest range possible.

I tried both of those and the results weren't as expected.
Had I not got a bit of resistance with the LED on, I would have thought this vactrol was dead.
