"Peak-to-Peak" meter.
For what are (were) they used? Got it for free.
Is it simply so I don't have to multiply by 1.414?
Be gentle. I'm new at all this and trying to learn.

Like this Senco PP2 ?

It's not really a "meter". It's a "Peak to Peak Comparison Meter",
whatever that means.

What's inside:

I couldn't find a manual or schematic. I have only some bad guesses
as to what it does and how it works. At least you didn't pay any
money for it.


I think it is a curve tracer of some sort.

Is that a line cord soldered to the metal can of the potentiometer?

Nasty.

Is the line cord polarized?

Did the Senco company get sued out of business by the widows?

No , it is soldered to a terminal strip tab that is embeddeded in
phenolic resin paper. The tab that is soldered to the potentiometer
case is also connected to the phenolic strip. There is electrical
isolation between the two tabs. It was a very common c practice in
the 1960s.


I was wondering, the photo looked like it was soldered oddly.

Thanks for clearing that up!
