The trouble is there always seems to be some kind of offset for example at the present time the onboard temperature api is returning 246 yet the external temperature sensor that is physically located right next to it is returning 235.

Is there any reason why there are differences?

I would like to move my project along, but cannot because i am not sure i can collect reliable values.

Thanks

I get this frequently if you do not close down the port and end you application. Eg press stop in vb. Then try to open it again.

The only remedy i have found so far is to reboot the computer.

Hi Sarah

What i did was to start the PicoLog Recorder, wait for the temperature to stabilize.

Then i took a reading, closed it down and started my application and took a reading from that, about 4 seconds.

Sometimes i did it the other way round, but it takes a bit longer.
