A friend has just given me a beautiful 1960-ish optical pyrometer. It is a Pyro Optical Pyrometer, made by The Pyrometer Instrument Co. with serial number 14081. Cannot find model or type.
Now. To the questions.
Does anyone know how this thing works? The physics I understand slightly, as in matching the intensity of a filament inside the pyrometer and comparing it with the intensity of the source to be measured. But what do these crazy knobs do?
- There is a switch knob with one position marked N and the other marked 3. Does anyone know what this does?
- Another switch marks High, Mid, or 0. This I know changes the intensity of a red filter. Why? Simply for looking at brighter sources?
- Is the intensity of the filament variable?
Does anyone know anything about these very antiquated (yet amazing) devices or know anywhere I can find out more about them? Of course I have googled them as well as checking out the Pyro brand website but can't seem to find enough definitive information about them. I was hoping one of you fine scholars and archivers of knowledge had come across this particular pyrometer and may have had the chance to work with one.
Any info helps.

Also if pictures are needed this is exactly what mine looks like:

This might also be informative (not very informative to me however)
