hello!!!
i am using 9205 module for measuring output voltage from heat flux sensors. the output voltage is in range of millivolts but 9205 is not responding accurately to these sensors. i did some test to check wether 9205 is functioning correct or not.
i connected a voltage source with 9205 and did a parallel connection to 9219 also which works perfectly with sensors (but there are only 4 channels)
but there is difference in values of both the device at millivolt range.
here is some samples from recorded data..
time NI 9205 NI 9219

please help me out and tell me
wether 9205 is working correctly or it has some problem.??
