Hello, I need to measure strain of 3 jauges (every jauge acquire strain of 3 directions). I would to know if i could use 3 unity of NI 9219 on one chassis? Because i tried to use 2 acquisition board and i get an error! I should use only one board! Thanks,

Assuming you want to account for the strain guage variabilities: Rotate the guages and place a known mass on top. Record the measurement with and without the mass. Adjust the channel's "Scale" Slope and offset per actual recorded values. Calibration of the 9219 is a different matter- It should have shipped with a certificate of calibration. Well, actually, they are on-line and you look them up by serial number from "MyProducts" on your ni.com profile (you do need to register your products!)

Simulating a cDAQ-9174 Chassis with 3 cDAQ-9219 modules in NI MAX does not generate any errors hence I'd say yes, it is possible. To make sure, I strongly recommend to contact your local NI service. Regards, Jens

3 unity of ni 9219 on one chassis

Solved!

Hey, Guess What! I was wrong!

But, its still a good idea to register your products
