problem acquisition with NI 9219

Hello,

 

I have  a NI 9219 with spring terminal connectivity mounted on a NI cDAQ-9172(8 slots) rack. When I input a sinuisoidal signal to the NI 9219 from a waveform generator, by connecting the pin n°4 and 5 of channel, I can't seem to acquire any decent sinusoidal waveform on labview or NI MAX. 

 

The sinusoidal signal is a 10Hz, 2volts peak to peak , 1 volt offset signal. I set the sampling frequency to 100Hz and number of samples to 1000. But still the signal acquired on the screen is weird and doesn't ressemble a sinusoidal signal. 

 

Is there a compatibility issue here between NI 9219 and NI cDAQ 9172? Can anyone help me please?
