How do I test a EM80 with Hickock 752?

I finally found European Tube Test data for my Hickock 752.

It says to connect a 1 megaohm resistor from plate jack to ocal test socket pin #7

I don't understand were the resistor goes.

One end of a 1meg resistor is plugged into the “plate” jack (normally used for tubes with plate.caps) and the other end of the resistor is plugged into pin 7 of the octal socket. To get reliable connections you’ll have to rig up some sort of an adapter using clip leads etc. PITA but it works.
