Target
The Model 2701-B can store up to four Gmb (Marshall) and
four Gmm (Voidless density) target values. A Gmb value is the
bulk density of a material, often determined using the
Marshall method. A Gmm value is the maximum theoretical
density for a test material as obtained in laboratory tests.
The gauge uses target values to determine the percent
compaction and/or percent voids (if a Gmm value is entered)
as compared to the measured density of the test material.
With the Target function, the operator can enter a new target
value, enable a stored target value, or disable a target value.
To access the Target function, press the
〈TARGET〉 key. The
gauge displays the Target menu:
To enter, enable, or disable a value, press the corresponding
numeric key. For example, to edit the Gmb (Marshall) value,
press
〈1〉. The gauge displays the menu shown below. The
Gmm(Void) Value: menu is similar and operates the same.
The target value menu shows the four stored target values (if
any) and the New and Disable options.
