The National Instruments USB-TC01 data acquisition (DAQ) device provides a Full-Speed USB interface for a single thermocouple channel. This user guide describes how to use the device. For specifications, refer to the NI USB-TC01 Device Specifications document available at ni.com/manuals. Figure 1. NI USB-TC01 Device... - Page 3 Working voltage is the highest rms value of an AC or DC voltage that can occur across any particular insulation. MAINS is defined as a hazardous live electrical supply system that powers equipment. Suitably rated measuring circuits may be connected to the MAINS for measuring purposes. 2 | ni.com | NI USB-TC01 User Guide...

NI USB-TC01 from the NI USB-TC01 launch screen. Creating Custom Software In addition to taking measurements with the NI USB-TC01 launch screen, you can also build custom software for your NI USB-TC01 with LabVIEW and NI-DAQmx driver software. LabVIEW uses graphical icons and wires that resemble a flowchart, so you can graphically wire together function blocks to create your own applications for logging data, alarming, triggering, reporting, and performing real-time data analysis. -

Figure 8. NI USB-TC01 Software Open Thermocouple Message Note During an open thermocouple condition, some invalid values may be returned before the open thermocouple is reported. Cold-Junction Temperature Measurement Accuracy Heat from other nearby heat sources can cause errors in thermocouple measurements by heating up the terminals so that they are at a different temperature than the cold-junction compensation (CJC) sensor used to measure the cold junction. -
