[Elecraft] K2: KAT2 Assembly

[b.denley at comcast.net]

I am assembling the KAT2 auto tuner.  Everything is going OK but I am having trouble with the following statement: 




'On the bottom of the KAT2 control board, locate a pad labeled "B". Just to the left of this pad you'll 
see the round pad for pin 1 of U4 (LM358). (You'll know you have the right round pad if it's part of a group 
of 8 pads, 7 of which are square.) Touch your DMM's (+) probe to this pad. Connect your DMM's (-) probe 
to any ground point on the K2.' 







Touch the probe to which pad?  T he one labeled 'B' or the little round one next to it? 



Anyone? 



Thanks
