The better the carrying capacity of the soil sample, the higher the generated plunger pressure. A soil CBR value is an index of the shear resistance under standard loading as compared to the shear resistance of a standard material (crushed limestone) under the same loading.
Page 5: Average Cbr Value; Calculation Per Penetration
Description The CBR penetrologger is normally supplied as a complete set for measurements to a depth of up to 70 cm. Such a set is comprised of the penetrologger itself, suitable CBR cones, conecheck key, probe rods, a depth reference plate, cable, software and a test protocol.

/ n (= No. of measuring values between X and Y = per centimetre of a measurement). Ø CBR average value is rounded down (e.g. CBR 7.9  CBR 7) Range for calculations: Ø CBR average value can be entered for 2 (CBR depth 1 (X) and CBR depth 4 (Y)) users.
Page 7: The Procedure
Practically, it is more convenient to make use of a PC (Chapter 6. Creating a plan on the PC). To this purpose the Penetroviewer CBR software needs to be installed on the computer. If the PC is now connected to the penetrologger via the communication cable, then the created measuring plan is transferred from the PC to the penetrologger.
Page 8: Planning The Measuring For Field Measurements
Planning the measuring for field measurements Creating a plan PLAN X This type of plan consists of a hierarchical structure Project of projects, plots and penetrations (see picture). A project consists of several plots (measuring Plotname positions). A penetration resistance is determined at Penetration each individual plot.

 Windows 7, 8 or 10 1. First insert the “Penetroviewer CBR” DVD into the drive. The Auto-Run program starts, follow the instructions of the screen. If the Auto-Run program does not start, then the Setup file can be started manually.
Page 10: Starting And Ending The Penetroviewer
1. To start the Penetroviewer, click the Eijkelkamp Penetroviewer shortcut in the Windows Start menu under Programs, Eijkelkamp Penetroviewer, Penviewer. Then a window with the Eijkelkamp logo appears and disappears again a few seconds later to be replaced by the main window of the Penetroviewer (see picture).
Page 11: Standard Parameters
Normally all values between 0 cm and 60 cm are used for average calculations of the CBRs per penetration. It is possible for the project to pre-select other areas (e.g. measurements between 10 cm and 50 cm). Type of cone The CBR cone type is pre-selected.

6.5.2 Saving and ending the measuring plan  As soon as the changes of the settings have been carried out, a window appears (irrespective how) with the query whether the changes should be saved or not (Yes/No/Abort). The saved plan can then later be used again or can be processed (see Paragraph 6.5.3) 1.
Page 14: Creating A Plan With The Aid Of The Penetrologger
The Penetroviewer possesses a “LOGGER INFORMATION” window with the serial number of the hardware and software versions. Close this window to continue. 6. Use Send plan in Datalogger in the menu bar to transfer the plan to the penetrologger. In a window, the operator guidance asks whether the plan is really to be transferred to the penetrologger.

Page 28: Numeric Depiction
9.2.3 Numeric depiction First select “Numeric” under “Plot” in the menu bar in order to call up a numeric overview of the currently selected measurements (penetrations). This brings up a measurement value for every centimetre of depth. If the average line is shown in the graphic depiction, then the numeric data of the average value and the respective standard deviations are displayed.

9.2.4 External processing of the measuring results  It is possible to save the lists as a text file (ASCII) with the suffix “*.txt”. For this purpose, select “Export TXT file per cm depth” under “Setup” / “Export” in the menu bar. In this the measuring results up to this point (selected measurements or average values with standard deviations) are saved.

10.1 Communication between thePC and the penetrologger  The Datalogger menu of the Penetroviewer CBR is not available although the penetrologger is connected to the PC via the communication cable.  First check whether the correct communication connection is set at the Comm. Port under Tools in the menu bar.
Page 34: Creating A Measurement Plan
10.3 Creating a measurement plan  The penetrologger or the Penetroviewer CBR does not permit the creation of a new measuring plan. First delete the current plan (Paragraph 6.4.2); it can possibly be saved first.  A new project cannot be defined.
Page 35: The Penetroviewer Cbr
10.5 The Penetroviewer CBR  The attempt to print out a graphic depiction of the plot results is unsuccessful. In this case, ensure that the printer is set to a maximum of 300 dpi (dots per inch).  The graphic printout is broken off at the edge of the paper. In this case it is best to print out the data with a spreadsheet program.
Page 36: Gps Receiver
 During use the ultrasonic sensor must be kept dry in order not to falsify the depth measurements.  Royal Eijkelkamp recommends that the penetrologger is serviced and calibrated once a year by the manufacturer.
