I found an actual manual:
http://hpsweb.hon...1i6226.pdf

And it IS capable of other inputs, which is very nice. My cobbled TC wires are giving readings either too high (900F) or too low (-300F), so I think there's high resistance open, or I'm not getting a good connection at the back, or I don't know what type of wire this was from my multimeter probe. Tried polarity both ways.

I do have setup questions regarding alarm adjustment range (direct acting, reverse acting, deviation and band).

Try shorting the t/c inputs together using a short loop of any kind of wire. Regardless of which type of t/c wire the instrument is expecting, it should show room temperature on the display.
