Electrically noisy or incorrect thermocouple measurements can occur if the USB cable is left connected between the logger and computer during your deployment.

It is STRONGLY advised that you use the LCD display on the logger to view temperature values rather than use the Status window in HOBOware.

If you absolutely must leave the USB cable connected, you need to invest in shielded thermocouple wire and/or a USB isolator, which can be very expensive.
