asphalt layers of 4 inches or greater. Use the number keys to select
either
Asphalt or Soil mode, or refer to page 5–10 for instructions on
enabling the Nomograph function for taking thin-layer
measurements. The gauge enables the selected measurement mode

DISPLAY BACKLIGHT
Both the Model 3430 Plus and 3440 Plus gauges provide a backlight
for the liquid crystal display (LCD). The backlight can help the
operator read the display at night. The Model 3440 Plus also
features a backlit keypad; this feature is not available on the Model
3430 Plus gauge. To activate the backlight, press the
〈
LIGHT
〉
key.
NOTE
Using the display backlight reduces the battery life. To
conserve battery life, turn the backlight off when it is
not needed. Also note that the backlight turns off
automatically after 3 minutes to conserve power.
NOTE
The gauge also features a hardware adjustment for the
display contrast. If the gauge display is difficult to read
in bright light, adjust the contrast as described in the
Display Contrast section on page C–9.
