Reading The Internal Temperature From A Labjack

[cadcoke5]

I am attempting to read the internal temperature from a Labjack U3.  I understand it is on channel 14, and is streaming.  I am fairly new, so perhaps my understanding of streaming is incomplete. Is this different from the the other channels?  When I create a Variable Value in a display, All I get for the value is " {0.3, 0.3, 0.3,0.3,0.3,0.3,0.3,0.3,0.3" .... etc. and then ending with a " 0.3}".  Even the value 0.3 does not make sense, since this should be the temperature in Deg K, and even though I just ran out of heating oil, it is not 0.3 above absolute 0. [Don't worry, I am using my gas cook stove for heat at the moment]

 

I set the channel as an A-to-D, which was a guess. But none of the other choices made sense to use.

 

How should I access the internal temperature from a Labjack U3?

The temperature sensor on the U3 is on channel 30.  See: http://labjack.com/support/u3/users-guide/2.6.4

 

I'm assuming by streaming you mean just polling, not high speed streaming and you have a non-zero Timing on the channel.  Yes you want A to D.  In your variable value display, don't forget to put [0] after the channel name.

Sorry, I try hard to not bug you with information that I should find in the LabJack manual. I searched and only found the info on a different LabJack unit, and figured they would be on the same channel. 

 

Thank you for your information, it is working great now.
