Scaling Voltage Measurements
Note NI-DAQmx includes thermocouple and thermistor conversion utilities that
implement the conversions required in steps 3 and 5 of the following procedure. Refer to
your software documentation for more information on these utilities.
Your software environment may return only voltage measurements from
E/M Series DAQ devices. If so, you must convert voltage measurements to
