I am very new with LabView. I need to record few temperature data using K and T type thermocouples and also voltage of a battery.
When I selected CJC source as built in , following error is showing :
Error -200077 occurred at DAQ Assistant
Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.
Requested Value: Built-In
Possible Values: Constant Value, Channel
Channel Name: Temperature
I selected constant value and select the reference temperature at 25 oC , It was not working , After that I fixed the reference temperature at 0 degree Celsius, It was not working,
I have used channel as CJC type, and I have selected one thermocouple as constant , and for another thermocouple I chose channel and refereed the first one as CJC channel.
Unfortunately nothing worked.
Could you please suggest me , how can I sort out of this problem using NI USB 6212 ? or what would be the best possible solution to measure the temperature using Ni DAQ?
your NI6212 does not support a CJC channel.
It's a "plain" DAQ device able to measure voltages…
You might use your device to measure TC-J/TC-K voltages (using the ±0.2V measurement range), but usually you should use a DAQ hardware made special for TC measurements!
(I also recommend to get rid of the DAQAssistent and use simple DAQmx functions instead.)
In this case,
can I use NI USB 6251 BNC Screw with a help of any electronic ice point or SC-68?
Looking for your reply.
with a help of any electronic ice point or SC-68?
You can use external sensors as reference…
What is a "SC-68"?
