Beginning to use the Thermo Eye is simplicity itself - Simple attach the relevant connector, plug in the battery correctly, and you're ready to go. The cables supplied with the device give you two separate temperature gauges, each with a cable length of one meter, giving you plenty of room to monitor a couple of different components or areas of a system without difficulty. Two small pieces of tape are also provided with the Thermo Eye, allowing you to tape the two sensors to wherever they are required, be it under a heatsink or anywhere else you deem it necessary to monitor temperature.
