MID ENERGY METER MENU
Part of the main menu loop and accessible with either of the navigation keys, the MID Energy Meter
menu presents the total, accumulated energy consumption. The affixing, M18 in the example below,
as well as the serial number that follows is information on the built-in CEMP energy meter. The
revision number given at the bottom row refers to the legally relevant firmware within the machine.
The integrity of the data presented with this menu is thoroughly checked and protected. One such
important test is the calculation of a checksum to verify that the program memory has not been
corrupted. The result of the latest calculation is always available with the Firmware checksum screen,
accessed through the MID Energy Meter menu with the lower right button.
If any of the tests fail and the machine concludes that the available energy meter data must not be
trusted, the information is removed from the screen and replaced with dashes. If the problem
detected has to do with the checksum calculation, the bottom row of the screen will say so.
Left: Data removed due to communication error
Centre: Data removed due to checksum error
Right: Appearance of Firmware checksum screen when error is detected.
