Hi guys,
could anyone help me to calibrate my strain gage. Cos I think my experiments are going in wrong way.
currently im using:
NI USB 9162
NI 9237
NI 9949
As showed here http://zone.ni.com/devzone/cda/tut/p/id/4172 and since i've set up my system to measure axial or bending strain like half bridge 1.
So for this set up ive screwed wires on 2,7,6 on NI 9949 as 2,6 to bend strain and 2,7 to axial strain.
the strain gauge's resistance is 120 ohm +-0,5% and Gauge factor 2,08 +-1% each.Transverse sensivity is 0,1%.
How do I calibrate my strain gage? Do i have to do it? I've seen this link http://digital.ni.com/public.nsf/allkb/892C84122A6501AE86257547007E5C53
and it wasnt so clear.
