negative temperature??

Postby Guest » Wed Jun 04, 2008 1:09 pm

I have an usb connected TC-08 .At first two or three measurement-two days ago-, everything was OK.

I havent changed any thing in my measurement setup;same motor, same sensors at same location (No body has touched them) ,same computer,same place...But now, two of the 8 k-type thermocouples shows negative values.

I think,there is no problem with data logger, because, when I connected these two sensors to other channels, temperature values remained negative.

So,I wonder what causes that negative temperature measurement.Can it be corrected by changing logger settings?

You may wish to try a new sensor in each channel at ambient temperature, just to make sure it is not a sensor problem.
