when run program which channel: ai temperature sensor, which is connected to the analog input of the property in waveform chart amplitude = 0.271v but when exposed to temperature sensor amplitude increased and fixed. 0.29v when setting the DAQ Assistant Express VI to scale the input signal by C = 100 * V set range min = 0 and max = 100 because the temperature is linear. This starts at 0 degrees Celsius when running the waveform chart amplitude = 25.7 ° C, the temperature inside the room. But when exposed to temperature sensor waveform chart amplitude = 27.8 ° C.
