I looked at a 500-C service manual (S/N 30001 - 49999, not knowing the S/N of your unit) and I found the instructions as confusing as you did.

So I looked at the procedure for the 500-B. The procedure appears to be the same, but the text is worded in a more understandable manner:

Quote:Hot lead of DC VTVM to Test Point 4. Ground lead of DC VTVM to junction of two series connected resistors (47K), wired between Test Point 3 and ground (emphasis mine).

Adjust: Z5 top

Indication: Zero indication on zero center dial.

So it appears that you add two 47K resistors in series between Test Point 3 and ground, just long enough to make that adjustment, then remove the 47K resistors.
