[Elecraft] Using Digital VM? (Control Board K2 # 5422)

I could use someone's help - to understand the
"resistance" measurement values, at the end of each
PCB's completion in manual.  I tried making readings
with an analog VM and got values too small for some of
them.

At a K2 builder's recommendation - I bought an
auto-ranging DVM. 

In measuring resistances for Control Board,
(page 21 table).  On a few Control Board measurements,
I'm getting MUCH higher resistances than table
indicates:

  U6 pin 13  supposed to be > 100k   got INFINITE
  U6 pin 14  supposed to be > 100k   got INFINITE
  U6 pin 29 & 30      to be > 70k    got 85k
  U8 pin 2            to be > 100k   got 6.6meg
  U8 pin 15 & 16      to be > 100k   got INFINITE

The INFINITE measurements I got for a few of the IC
pins - were right up there, like an "open"?  I don't
know how to interupt this with a DVM?  

Do these readings sound reasonable?

Thanks, 73's
