10.7 DIM
The DFX-7 has a built-in DIM feature to manage power more effectively. This feature
has adjustable time durations, until the power of the display is dimmed and current
draw reduced. The timer is constantly reset while the user is making measurements,
and is only activated when the gauge is idle for the duration of time the DIM value is
set for. This feature does not override the preset 5 min idle power off feature in any
way. However, if the gauge is turned on, set for a DIM of 120sec, and then left idle
for 5 minutes, the DFX-7 will dim in 2 minutes, then power off in 5 minutes. The
procedures for adjusting the DIM time are outlined below:
Setting a DIM time
1) Press the MENU key once to activate the menu items tab. Press the MENU
key multiple times to tab right and the ESC key multiple times to tab left until
the DISP menu is highlighted and displaying the submenu items.
2) Use the UP and DOWN arrow keys to scroll through the sub menu items
until DIM is highlighted.
3) Press the LEFT and RIGHT arrow keys to scroll the DIM time.
