You will see a window pop up with the heading Survey Wheel Calibration (Figure 13). This is where
you enable the specific survey wheel device you are using with the SIR 20 and determine how many
internal ‘ticks’ per selected unit of distance.

If you have a StructureScan minicart, click on the image of the cart that you have.

If you have an Optical cart, click the image of the blue minicart.

If you have a different survey wheel device than the ones pictured, then you must calibrate your
survey wheel.
