Software Update Steps of LSG-1800BCCD/LSG-1700BCCD/LSG-5000CCD

LISUN will irregularly update the software of LSG-1800BCCD/LSG-1700BCCD/LSG-5000CCD. However, since each spectroradiometer in the system has its own independent hardware data file, we need to back up the hardware data file before updating the software (The step 2 below). The software cannot be installed without the hardware data file, and the use of the wrong hardware data file will cause deviatio...
