  • Page 7: Introduction

    The output of the Geokon Model 6101 MEMS tiltmeter is equal to +/- 4 volts at +/- 15°. When used with a GK- 603, or GK-604 readout box, set to a gage factor of approx 0.62 (the exact gage factor is shown on the calibration sheet), the display will be 20,000 sin ...
  • Page 8: Taking Readings

    For Horizontal installations point the Peg #1 in the same direction as the expected tilt 4. Taking Readings ________________________________________________ Connect the sensor to the readout and check to see that the system is operating. Clean all dirt from both the sensor and the tiltplate.
  • Page 9: Data Recording And Reduction

    Peg 1 reading = 82 and Peg 3 reading = –99 DIFF = (82) – (–99) = +181 The conversion of this difference to degrees of angle is done as follows: Reading with either the Geokon GK601 or GK 603 readouts DIFF –1 –4...

  • Page 11: Troubleshooting

    A tiltplate tilted at an angle and located on a stable surface can be read periodically to check the calibration of the instrument. The sensor itself should not be opened in the field and if the unit fails to work it should be returned to Geokon for repair.
