FIRMWARE PROGRAMMING
On occasion it may be necessary to update the internal software of the analyzer, also
known as the firmware. The firmware can be updated in the field with the use of a
computer connected to the E8500 Plus analyzer. Firmware updates can be requested
from the factory. The current firmware version is displayed on the second status screen.
Updating the firmware

analyzer. There are 2 miniature slide switches on a black block.
2. Connect communications between the E8500 Plus and the computer. Run the
firmware update. The program will backup the analyzer’s settings.
3. When prompted, toggle the switches on. The firmware will now be
reprogrammed. This will take 2 to 3 minutes.
4. When prompted, toggle all the switches off and replace the batteries and cover.
The analyzer’s settings will be restored.
