Function Keys
The H5001EZ features Four function keys, F1 through
F4, for each one of the display lines. With few
exceptions, each key is assigned a unique task specific
to its assigned menu. For simplicity, tasks common
to each menu will be represented, when and where
possible, consistently in sublevel menus with matching
graphical representations and locations. A line with an
(*) indicates an action function line.
Maximum Density
This key allows entry of information pertaining to characteristics of the
material under test. MAX D is the target density for percent compaction.
For soil, it is normally a value based on a laboratory Proctor test. For asphalt,
it is a value based on a laboratory Marshall density or maximum theoretical
density. The value set into this register must never be set to a value outside
the range of normal soil or asphalt densities. Anything between 900 kg/
m³(56 PCF) and 3000 kg/m³(200 PCF) will not cause processor errors.
It must never be set to 0.0.
Standard/Statistical
The STD / STAT key initiates a 4 or 16 minutes count of both the moisture
and density channels when the handle is located in the SAFE position.
It retains the values so that they can be used to ratio all the subsequent
measurement counts. The last four values are stored and may be displayed
by pressing
MAIN MENU, F1
(*DATA), and then
F2
(*STATS / STD).
Measurement
This key initiates a measurement using a 4 minute, 1 minute or 0.25
minute periods as previously selected. The actual counts are put into the
display and the time remaining before the end of the measurement. After
completion of the measurement, the dry density (DD), wet density (WD),
