Microsoft Excel displays the timestamp contained in the wireless node data files incorrectly.  If you were to open the CSV file with Microsoft Notepad, you will see that the timestamp is shown properly.  In order to get Excel to show the human readable time, follow the below procedure:

  • Highlight all of column A (column with the timestamp)
  • Right click on highlighted region and select Format cells...
  • Select the Number Tab in the window that open and choose Custom from the Category box
  • Scroll to the bottom of the list in the Type box, find this entry: m/d/yyyy h:mm and click it
  • Add to the entry an :ss.000 so it now looks like this: m/d/yyyy h:mm:ss.000
  • Click OK

The timestamp will now be correct.

From time to time the inertial sensor may need recalibration.

Example: If the inertial sensor contains magnetometers, coming in contact with magnetic influences (magnets, motors, etc.) may cause residual magnetism to be picked up by the on-board components which alter the calibration.  In these cases, the inertial sensor should be returned to the factory for recalibration.

Example: The inertial sensor receives a severe shock, slightly altering the position of the circuit boards in relation to the enclosure, again altering the calibration.  In these cases, the unit should be returned to the factory for recalibration.

Yes.  The unit is factory calibrated and ready for use with power-up.

Physically, the 3DM-DH3 is easily mounted into the drill string using its body’s threading attachments. It can be tethered to an RS-422 communication cable for continuous real-time measurements to a host computer during drilling operations, or it can be remotely deployed and run as a datalogger, with data retrieval after it has been run through the drill path. The unit can be powered through the communication cable tether from a platform source or by batteries.

The 3DM-DH3 has measurment accuracy of +/-0.2 degrees inclination and +/-0.5 degrees azimuth.
