New test at ambient temperature (Check operation of the data acquisition system)

After you have verified :

• The operation of the converter V/I
  
• The independence of the four differential channels (DF0, DF1, DF2, DF3)
  

I made the following misura at ambient temperature (Real-time):



The main components of the system acquisition:

• Data acquisition card CB-68LP Natioal Instruments
  
• Converter V/I
  
• Generator voltage
  
• Thermometer DT470-SD
  

The figures below show the acquired data (every 10s) with the software built with LabVIEW 7.1
