Hi Drifter,
I tried using the Map Range Scale in LabVIEW SignalExpress version 2.5 and had no problems. I mapped a 2-10 V signal to a 0-3000 scaled value.
What version of SignalExpress are you using?
What version of the NI DAQmx driver do you have?
Did you ever calibrate your DAQ card before scaling?
Try using a Linear Scale to essentially do what the Map Range would do. Keep me posted on your results.

Hi drifter,
I believe the reason your signal is railing at 1300 is that Input Range was not
configured after you setup your scale. The KnowledgeBase
article, KB 33BHM4E6: DAQmx Custom Scale Type Map Ranges Do Not Display Correct
Value, describes where to setup the Input Range. For your application,
you will change the Min to 0 and the Max to 3000. Let me know if changing
the values works.
