measure temperature with pt100?

when i connect two pt100 with 4-20mA outputs, the first pt100 i have connected to ch1 and the second to ch2, and the problem is that the measurements get frozen and stay in static number, but when i disconnect any pt100, measurements got defrost, so i can only read one pt100 connected at time...................
