The 3DM-DH3 is operated by a combination RS-422 communication and power cable, part number 4005-0003.

 

 

The FAS-A is operated by a combination RS-232 communication and power cable, part number 6208-0020.

The FAS-A analog out port uses an analog cable with flying leads, part number 6208-0010.

The 3DM-DH is operated by a combination RS-232 communication and power cable, part number 6202-0020.

The term ‘static’ accuracy refers to measurements made when the inertial unit is not moving and the on-board orientation algorithm has recovered from any sensor over-ranging.

The term ‘dynamic’ accuracy refers to measurements made while the inertial unit is moving and not exceeding the measurement range of the individual on-board sensors (accelerometers, gyroscopes, magnetometers).

The 3DM, 3DM-DH and FAS-A are designed to measure static rotations.

The 3DM-GX3 family is designed to measure both static and dynamic rotations.

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.
