RTD read channel data

 1'''
 2Temperature_RTD - RTD_read_channel_data.py with asynchronous mode.
 3
 4This example demonstrates how to read RTD data in two channels from USBDAQF1RD.
 5
 6First, it shows how to open thermal port
 7Second, read channel 0 and channel 1 RTD data
 8Last, close thermal port.
