Knowing and documenting the expected response is a given. Without 
this information the instrument's usefulness is diminished.  The 
original question related to whether or not each instrument had to 
have its own check source. It is still my opinion that if the check 
source is close to the instruments in question, can be checked 
everytime the instrument is to be used, and, the survey test is 
documented, then there does not need to be a unique check source 
attached to each and every instrument. That was the question, this is 
my opinion, good or bad.
