• The upgrade package is contained as a folder within a ZIP file. Extract from the ZIP file the folder (called 'centauri_upgrade') and copy this folder to main directory (the root) of a USB flash drive.
  Note: The USB flash drive must be up to 32G and formatted as FAT32
• Insert the USB flash drive into the USB port that is found on the upper panel of the meter (see Figure 1).

• Turn on the Centauri while simultaneously pressing through the pinhole for a few seconds.
• The upgrade procedure starts, with a progress bar displayed on the screen.
• When the procedure is completed, the Centauri restarts with the new firmware version.

Disclaimer:

• The new Centauri firmware is based on a new Android version so once upgraded there is no way back other than loading the instrument with production firmware.
• Upgrade from older version may take over 5 and a half minutes.
• The logs stored in the instrument will be deleted (Save them in a USB disk drive before the instrument is upgraded)
