After turning the gauge on, you can set several parameters,
including measurement units and count time. These parameters
do not usually change once they are set.
The gauge offers a
Status
function that enables you to view
selected information about the current gauge status and setup.
To access this function, press the
¢
STATUS
²
key.
The gauge displays two screens of information, including the
measurement units, count time, measurement mode, battery
status, Gmb (Marshall) value, Proctor value, Gmm (Voidless
density) value, and measurement depth. Use the arrow keys to
scroll between the two screens.
To begin, press the
¢
SETUP
²
key. For information on all of the
functions available from the
Setup
menu, see Chapter 5: Setup
Setting the Count Time
The
count time
defines how long the gauge measures. Longer
count times produce better measurement precision. Troxler
recommends a count time of one minute for most sample
measurements.
To change the count time, press
¢
1
²
at the
Setup
menu. The
gauge displays:
TIME: 1 m
1. 15 sec
2. 1 min
3. 4 min
The first line displays the current count time. Select the desired
count time using the corresponding number key. The gauge sets
the new count time and returns to the
Setup
menu.
