AI-110 current reading issue

I am wiring in a pressure transducer that contains a 4-20 mA output. I have wired up several very similar things and never had a problem, but I am having an issue this time. When I connect the output from the transducer to the current in channel on the DAQ module I am recieving no response. However if I skip over the I-in channel and use a mulitmeter to complete the circuit I am reading the proper current levels. I have tried several different modules to be sure that the one I was using was not working correctly and had the same issue. I haven't come across this before and am unsure as to what to do.
 
Thanks for the help,

Problem solved. I found out that the module I was using along with the others I had tried had been completely soaked with water. I tried a new dry module and it worked fine.
