Hi Frank,
I translated your post using Google, so I hope that I understood your problem, in order to avoid the problem in reading the RTD temperature using the tasks, you can do the following, use the DAQ assistance express vi, configure you task there (same as what you did in MAX), when you are done with the configuration right click on the DAQ assistance express VI, select Open front panel, then press "convert" when prompted. Using this way I am sure you will have the correct readings from the RTD channel same as MAX.
