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:
-Target-
1. Gmb(Marshall)
2. Gmm(Voidless)
Press # to Select
To enter, enable, or disable a Gmb (Marshall) or Gmm (Voidless
density) value, press the corresponding numeric key. For example,
to edit the Gmb (Marshall) value, press 〈1〉. The gauge displays the
Gmb(MA) Value: menu shown below. The Gmm(Void) Value:
menu is similar and operates in the same manner.
Gmb(MA) Value:
1. #.# 2. #.#
3. #.# 4. #.#
5. New 6. Disable
The target value menu shows the four stored target values (if any)
and the New and Disable options.
ENABLE A TARGET VALUE
To enable a displayed target value, press the corresponding numeric
key on the target value menu. The gauge enables the target value
and returns to the Ready screen.
