Function Keys

Function keys, or F keys, such as F1, F2, and F3 have various gauge functions and may
change depending on the display screen. View the bottom of the display screen for the
function that corresponds with the appropriate F key. For example, F1 may correspond
with the Save function, F2 with the Freeze function, or F3 with the Directory function
(Dir).

Display Screen

The gauge has a graphic style color TFT with 270x220 pixel density. Viewing the screen
is best from straight above or slightly below the surface rather than from side to side. If
external temperatures are below 32F (0C), the display may be slower to update
information.
At the top right corner of the display screen is the "available key mode".
