K1 and DMM resistance checks

roney
Hello, I'm just building my first K1.

Everything is going right, I had already build the filter board, the front
panel, and now in main board.

I have a question about resistance checks using DMM:

- Every time when the manual says that in some point the resistance must be
> 100K, my multimeter shows 1, just like there was no resistance. Is that
right ?

For all other resistance checks in specific values or ranges, it's working
as expected.

I just need to solve this doubt in order to proceed.
(now I'm on page 29 from manual)

Thanks and 73

Roney,

If it is an auto-ranging meter, it is okay.  1 just means open, which is
greater than 100k ohms.  If it is not an auto-ranging meter, make sure you
select a range that will measure at least up to 100k ohms.  Again, 1 would
be okay.

Roney,

You are a bit confusing when you say "no resistance".
No resistance normally means zero ohms.
It seems your DMM is responding normally to an infinite resistance.
If the reading is the same as your DMM reads with nothing connected to
the leads, that is a resistance higher than your DMM can read.  Increase
the scale.

If the manual indicates >100k (greater than 100k) then infinite
resistance qualifies as good.
