CHAPTER 4 COLLECT
4-17
NON-STANDARD SPACING or NON-STANDARD DATA COLLECTION
The Dipstick you purchased can be used without any other attachments to measure at any of three
different data spacing intervals – 250 mm, 300 mm, and 12". Note that 300 mm is not exactly the
same as 12". There are 3 pairs of holes in the bottom "tang" of the Dipstick. Each hole is marked
either "12", "250", or "300". If your moon feet are in the two holes marked "12", you are
measuring at 12.000 inch data spacing intervals. Similarly, if you place the moon feet into the
holes marked "300", you are collecting data at 300mm intervals, or 250mm intervals, if you use the
holes marked "250". Don't forget to zero the Dipstick any time you replace or adjust the feet.
When you move the feet to different foot spacings, you MUST also change the Hardware settings
in the data collection menu. SETTINGS/HARDWARE then FOOT SPACING.
If you wish to collect data at smaller intervals than 250mm or 300mm, you may do this with the
Variable Foot Spacer bar. Remove the kickstand, washer, and spacer. Install the variable foot
spacer bar by screwing it onto the "tang" at the bottom of the Dipstick with the 2 screws provided.
The variable foot spacer has many holes on the bottom. Measure the distance between any two
holes in the bottom of the variable foot spacer bar. (Do this centered on the bar, so both feet are
approximately equal distance from the center of the bar.) Choose the two holes that have the
desired data spacing. Install the Moon Feet into these two holes in the variable foot spacer bar.
Don't forget to zero the Dipstick any time you replace or adjust the feet. When you move the
feet to different foot spacings, you MUST also change the Hardware settings in the data collection
menu. SETTINGS/HARDWARE then FOOT SPACING. Don't forget to change the Hardware
Settings back to your normal settings after you move the Moon Feet back to their normal spacing,
and rezero again.
MERGING DATA FROM DIFFERENT DIPSTICKS
When you need to evaluate data collected by different Dipsticks on the same project, you may use
TOOLS/MERGE to get all the data into one job for convenient analysis. (Note: The
TOOLS/MERGE function is only available in the RoadFace program, not the RFCollect program.)
When you use the Merge feature, you actually make a copy of the second job and place it in the
first job. (You still have the second job, unchanged, in addition to the first, merged Job, which
now contains the data from both jobs.) The details are covered in Chapter 5, Process Data.
STEPPING OVER WIRE MESH OR REBAR
The Road Dipstick kit contains two "leg extensions" which will help you collect data through
potholes or over wire mesh or rebar. Simply screw these extensions into the proper holes on the
bottom of the Dipstick and screw the Moon Feet into the leg extensions. Don't forget to re-Zero
whenever you remove or install Dipstick feet.
