Compass Calibration (IMS-5)

How to Calibrate Your IMS 5 Camera

You may see compass-related warning messages in Survey periodically. (See Figure 1)

Figure 1 - Compass Angle error

This is normal and generally means that the compass can not get a good reading. If these messages become more frequent, it is recommended to calibrate the compass.

Once in Survey, this can be done by going to the Manage tab in the bottom right-hand corner of the screen and then tapping the calibrate compass button.

You will then be given three options. (See Figure 2)

1. Show How-to Video,

2. OK

3. Cancel

Figure 2 - calibration options

To start the calibration immediately click OK, or watch a How-to video on how to complete the process.

If you are viewing this document on a computer, you can also click here to view a How-to video with demonstrations.

The how-to video is built right into the camera and it shows you how to move the camera, so the compass can get the information needed to calibrate itself.

There are three movements you are required to complete:

Front to back	Left to Right	Twist

Watch the video as many times as needed. To begin calibration, click the OK button.

Note: Camera rotation should be performed slowly and should take about 10-20 seconds to complete. If the calibration data collection is not completed in 60 seconds, the procedure will time out and will need to be repeated.

Move the camera around as you saw in the video, and then tap Finish. You should then see a message that says: “Compass was calibrated successfully”, you may then tap OK to clear this message.

If you are unsuccessful, please make sure you review the steps required and retry the process.
