am at red control machine ,and do not remember where the wall gauge is to check my reading ? how do i get to them from here ? so sorry - i am always lost . thank you for any help....

You are in Hall B.

You want to go to the red colored walkway close to the cablecar area. The gauge should be on the wall at left side.

yes ,but do i go to hall a ? i can't remember how to get to that area...

Hi niteowl,

The gauge is in the red walkway itself, you don't need to go as far as Hall A.

thank you both- the problem was that those little skill icons were hiding the spot i needed to click on - i knew where i needed to be , just couldn't get there -this is some pixel hunting sometimes with this one....but i found the gauge finally !

Glad you found it.
