20120110653 | MEASUREMENT DEVICE AND METHOD FOR LOGGING USE OF THE MEASUREMENT DEVICE - In a method for managing use information of a measurement device, an operating interface of the device is locked before the device is operated. When a user starts to use the device, the method provides a login interface to verify whether the user is authorized to login the operating interface. If the user is authorized to login the operating interface, the operating interface is unlocked and the method records first information of starting to operate the device. After finishing the operation or when an elapsed time of the device not in use is greater than a predetermined time, the method controls the user to log out the operating interface, records second information of finishing the operation, and the operating interface is locked. The first information and the second information are saved in a text file. | 05-03-2012 |
