A digital thermometer includes a housing having a measurement tip, a user interface control to receive input from a user, a display for displaying temperature measurements, a data connector for insertion into a compatible port on an external device, and various components inside the housing including a temperature sensor, a wired/wireless communications unit, a controller to control operation of the thermometer based on the device software and input received from the user, and a memory storing temperature measurements, device software relating to control of the thermometer, and user software relating to instructions to be executed by the external device. Upon detecting that a communication link has been established between the thermometer and the external device, the user software is uploaded to the external device, and is caused to install and execute. Thereafter, temperature measurements are uploaded from the thermometers memory to the user software on the external device.
