9. The Dipstick can be used to measure the difference in elevation across construction joints ,
where two slabs are supposed to be at the same plane.
10. The Dipstick can be used to measure the motion of a slab as a piece of heavy equipment
passes over a joint. If the Dipstick is placed so that each end of the Dipstick is resting on a
different slab, across a construction joint, and a piece of heavy equipment is driven across the
joint nearby, the Dipstick
can measure the deflection of the slabs at the joint in real time.
11. The Dipstick can be used to measure the straightness or "trueness" of any tools used to
strike off or float wet concrete, such as screeds, highway straightedges, floats, and the like. It
has been shown that the finish flatness and levelness of cured concrete is directly affected by
any bends, "kinks," or dents in these tools.
12. The Dipstick can be used to measure the elevations of concrete forms before placement of
concrete. It has been shown that concrete is never flatter nor more level than when it is first
struck off from the forms, so the shape of the forms can be the limiting factor in the quality
of the resulting surface profile.
13. The Dipstick can also be used to measure the flatness and levelness of floors using the
ASTM E-1155 F-Number system. (F
F
and F
L
) The Dipstick is the fastest and by far the most
accurate way to measure floor flatness and levelness.
14. Actually, the Dipstick excels at just about any application where very precise elevations or
elevation differences are desired.
15. In addition to measuring at a precise 12" interval, all new model Dipsticks can also measure
at 300mm and 250 mm spacing without any mods or attachments, and the variable foot
spacer bar (standard with the Road model Dipstick) will
allow measurement at any data
spacing between 3" or 75 mm and 12" or 300mm. An optional adapter can be used to
measure at 24" or 500mm intervals.
16. The Dipstick's built-in software will provide a report in editable Rich Text Format and a
graph of the profile(s), either of which can be displayed on the Dipstick computer's screen or
printed. Tables of elevations and elevation differences can be viewed on the Dipstick
computer's screen, printed, or an ASCII text file can be created from the data which can be
exported into any spreadsheet, word processor, or other program. Certain reports can be
"batch-processed" that is, many graphs or reports can be sent to the printer at one time, or
many ASCII elevation files may be created at one time, or many Runs may be edited at one
time.
