TC-08 strange readouts

Postby SJKebab » Fri May 21, 2010 1:30 am

Hi all,
I'm using some custom software to read 1 ADC-20 and 3 TC-08s. As you'll no doubt know, when a TC-08 channel has nothing plugged into it, it'll generally output a temperature that's roughly the room temperature that the logger is at, due to the CJC.
2 of the loggers are outputting expected values, however one of them is outputting very odd numbers. All 8 channels will spit out somewhere between 11 and 22 degrees - the room temperature is about 22. All 8 channels will have roughly the same output, but there's a lot of variation there.

Are there any known issues with using these loggers on an underpowered usb port*? That's the only thing I can think of other than the CJC or the logger itself being dead.

Cheers.

*I'm not going through a hub or anything, this is only a suspicion...

Hi,
Your TC-08 should not be doing that. Please contact us on Help desk so you can return it for checking:-
