System upgrade includes the following two methods: • During the start-up period after the instrument is powered on, through the USB interface on the front panel, select the system upgrading files in the memory device (USB flash drive) for upgrading.
  • Page 202 For example, when there are multiple system upgrading package post- fixed with .itech in the root directory of your USB flash drive, you need to use a text editing tool to open the configuration file and specify the up- grade package name corresponding to the present upgrade operation.
  • Page 203 After the system upgrading files are detected, the interface displays as follows: Update Select(xx/yy) SN: ALL xx means the number of selected instruments to be upgraded, and yy means the number of instruments in the parallel network. Copyright © Itech Electronic Co., Ltd.
  • Page 204 The system will automatically perform upgrading. If No is selected, it means to exit upgrading, and the system will di- rectly enter into the main interface. 5. After the upgrading is completed, you need to restart the instrument manually. Copyright © Itech Electronic Co., Ltd.
