Model 3450
3–23
The gauge displays the voidless density and Marshall values
entered, and asks if the operator wants to store the pair. To store the
pair, press
〈YES〉. Pressing 〈NO〉 allows the operator to use the
values without storing them for later use.
The gauge can store the pair in one of three memory cells. Storing a
new pair in a cell erases the old pair. At the Select memory cell
prompt, use the number key that corresponds to the desired cell to
store the pair.
The gauge enables the pair and returns to the Target Value menu.
Return to the Ready screen by pressing the
〈ESC〉 key.
DISABLE A PAIR. To disable the Marshall value/voidless density
pair, press
〈5〉 Disable at the Pairs menu. The gauge disables the
pair and returns to the Target menu. Return to the Ready screen by
pressing the
〈ESC〉 key.
MEASUREMENT MODE
The Model 3450 provides three measurement modes (Soil, Asphalt,
and Thin Layer) for precise readings on base and thin layer asphalt,
concrete, soil, soil-stone aggregate, and similar materials. Before
taking a measurement, select the appropriate measurement mode.
To select a measurement mode, press the 〈MODE〉 key. The gauge
displays:
Use the Soil mode when measuring soil or a soil-stone aggregate.
Use Asphalt mode when measuring concrete or asphalt layers of 4
inches or greater. Select the Thin Layer mode when measuring thin-
layer asphalt of less than 4 inches. Use the number keys to select the
mode.
