Need info on Hickok Model 209A

[Tubejunke]

Anybody got a user manual or any information on this Model 209A? This thing is a super cool looking and well made instrument. However, Hickok tends to be a bit convoluted in their settings on their test equipment. I also have a tube tester by them. I may post on that separately.

With this thing, I need to know how to set the darned thing for the MANY functions it is capable of performing. I have both the AC and the DC probes and a single smaller lead that so far I have only been able to use as a DC ground. There obviously was a second lead that you plug into ohms, capacitance, and mili. I tried putting a paper clip in one ohms socket and jumping to the other ohms socket in hope of getting a "zero" sweep for the ohm meter. No such luck! Something must be wrong with the ohmmeter because when resistance is dialed in, the meter just sits at about 3/4 deflection and it can't be zero'd.
