I've been a Metrologist for many, many years..back when Lowry was teaching it..so am having a hard time teaching these whipper snappers some techniques...
Anyways, got a question, maybe some of you Old Schoolers can help...
Set up:
Analog pressure gauge, 0 - 100 PSI, minor increment 1 psi
I recall I was trained to "interpret" the space between the divisions. I.E. 1/2 way would be 0.5 PSI, "not quite half" 0.25 PSI.
Does anyone have any documentation they can direct me to that teaches that technique? or in fact teaches how to perform that type of analog measurement?
I'm in a debate with some peers and the frame of thouhgt is to aaply pressure until the UUT reads a nominal set point, then read the digital pressure source, and record it.
The debate then becomes which is correct? You get more resolution reading the digital standard, however the UUT is the devce under test. So, philosophically that would be incorrect.
TIA
