How can I make an accurately measure an 4-20mA Signal with the SCXI-1303 and DAQ-Assistant?

I have problems in displaying an 4-20mA signal with the DAQ-Assistant. My are collected about the terminalblock SCXI-1303 which is connected to the SCXI-1102B. Which type of analog data acquisition have to be chosen to get an accurate signal?

The SCXI-1102/B in combination with the SCXI-1303 is meant to be used to measure temperatures with thermocouples as the SCXI-1303 has an isothermal construction.
In order to measure current you need high-precission shunt resistors across the inputs. You can use the SCXI-1303 for this purpose by adding your own resistors but a much better choice would be to use the SCI-1308 that has 249 Ohm shunt resistors built in.

I can't tell from your very brief posting if this is the point of your question but it seems to be the most probable to me.
