Hi
I'm measuring strain with high elongation strain gage, I reach 20% of
strain.
Until now I use to use the NI 9219 module with NI9178
adquisition sistem, puting the gages in quarter bridge and measuring
correctly the strains (they were always under 4%). But if I try top put
the upper limit of striain in 200m, the software returns me an error
telling that the limit for my gage are 50m,-400m.
Whay tath happens?? Do someone know how can I fixed it? I hava tried
also with the NI9945and NI9237module but is always the same problem. My
gages have 20.095 gage factor and 350ohms grid resistance.
Thanks a lot!
