    The steps described in section 2.1 are an attempt to guide the user through the process of launching the GK-604D IRA, connecting to the probe and taking a survey. If all parts of the GK-604D are purchased as a system, Geokon makes every effort to ensure that the system is completely set up and working before it leaves the factory.

    APPENDIX A. Inclinometer Theory A.1. Inclinometer Theory In the geotechnical field inclinometers are used primarily to measure ground movements such as might occur in unstable slopes (landslides) or in the lateral movement of ground around on-going excavations. They are also used to monitor the stability of embankments, slurry walls, the disposition and deviation of driven piles or drilled boreholes and the settlement of ground in fills, embankments, and beneath storage tanks.

  • Page 80: Conducting The Survey

    Switch on the FPC-1, turn on the Remote Module (blue light blinking) then launch the GK-604D IRA. After verifying that the hand-held unit has connected to the probe, click on the “Live Readings” menu and observe the inclinometer reading.

  • Page 81: Checksums And "Face Errors" On Inclinometer Probes

    Make sure that the GK-604D IRA is set to Data Set 1.Take the first reading, pull up on the cable until the next cable marker sits in the cable hold and, after a short pause, take another reading. Continue in this way until the top marker is reached, remove the cable hold, pull the inclinometer out of the hole.

  • Page 82: Effect Of "Face Error" On Reading Accuracy

    A.3.1 Effect of “Face Error” on reading accuracy The “face error” or check-sum can only affect the accuracy of the readings if it affects the calibration of the probe. This is possible because the output of the probe transducer is proportional to the sine of the inclination from the vertical and the sine function is non-linear.

  • Page 83: Measurement Of "Face Error

    A.3.2 Measurement of “Face Error” The “face error” is the reading shown by the inclinometer probe when it is perfectly vertical. In practice , the easiest way to obtain the “face error” is to run a normal inclinometer survey, with the two sets of readings at 180 °, and then to run a profile or deflection report.

  • Page 84: Conclusion

    (i.e.2 sets of readings at 180°) It has further been shown that the best method by far, for setting the “face error” to zero, is by means of the software capabilities in the inclinometer reader. This is the method chosen by Geokon.

  • Page 94 6001-E,126543 NOTES: The GK-604D IRA uses the serial number to determine the appropriate probe units (metric or english) by reading the model number portion of the serial number string (the part to the left of the comma). If the model number does not contain a “-E” or a “–M” then unpredictable results may occur.

    11. Tap the “Yes” button to start the data saving process. The “Save File” dialog will be displayed, allowing the user to name the data file to save (see Figure 82). Figure 82 - Save File Dialog 12. After tapping “Save” the GK-604 IRA will determine if the file exists. If this is a new file then the data will be written to it in a format similar to the standard Inclinometer format.

    13. Tapping “Yes” on the “File exists” dialog allows multiple reads for this location to be stored in a single data file. See section G.1 for an example of Tiltmeter data format. 14. Tapping “No” at the “File exists” dialog will again call up the “Save File” dialog (see Figure 82) and another opportunity will be given to select a new file.

    Unlike an inclinometer survey, a spiral survey only requires A+ data so a second pass is not necessary (do not tap Dataset after first pass). When done the survey, tap “Menu->Exit Live Readings” and the screen shown in Figure 86 will be displayed. Tap “Yes” to save the compass survey data.

    H.2 Inclinometer/Compass Probe (6100D-X) As of probe firmware version V2.5, coupled with the GK-604D reel assembly (also V2.5), all digital inclinometer probes now include a 3-axis, magneto-resistive, compass sensor survey (see Figure 87). The compass sensor coupled with 2 axes of MEMS, allow a spiral survey to be performed at the same time as the inclinometer.

  • Page 113: Figure 88 - Compass Enable Message

    After entering a name, tap “Menu->Save Settings”. If the hole to be surveyed has an “UNKNOWN” probe assigned to it then the GK-604D IRA will ask if this newly discovered probe should be assigned to this hole (see Figure 9).

    With the compass enabled, a survey is performed as normal (see Section 3.3.1) and the compass heading can be displayed at any level by tapping on “Menu- >View Compass Data”, displaying the screen shown in figure 89.

  • Page 115: Calibrate Compass

    H.2.1 Calibrate Compass For optimum accuracy, the digital inclinometer/compass probe should be calibrated for each site. The GK-604D IRA provides a dialog to facilitate this (see Section 3.2.1.1 and Figure 33). A compass survey does not need to be enabled to perform the calibration.

  • Page 116: Figure 91 - Calibration Routine

    Figure 91 - Calibration Routine As the instructions state, the probe should be held in an upright position and slowly rotated through at least 360 degrees. The large rotating blue “arrow” serves 2 purposes: one, it indicates to the user that the probe should be turned and two, it provides feedback that the calibration routine is still running.
