The Cordel Wave-OEM requires some configuration and calibration to operate at optimal accuracy. For most applications, the unit will arrive with the correct configuration and an approximate calibration. Contact Cordel Pty Ltd for more information if required.

## Lever Arm offsets

The INS system requires the lever arm offset to be inputted for the INS to the Primary antenna. For this to be as accurate as possible please measure the offset from the INS module to the primary antenna upon installation.

Cordel Pty Ltd will often preset these values when doing a custom installation based on client information. If this is the case, there is no need to measure these values. If the system undergoes a custom installation or realignment, contact Cordel Pty Ltd with the measured lever arm offset. Millimetre precision on the lever arm offset is preferred, however, for hard to measure installations centimetre accuracy is acceptable.  

An example of this measurement is shown below.

## Dual Antenna offsets

Similarly, to the lever arm offset of the primary antenna to the INS system, the lever arm offset for the primary to the secondary antenna should also be measured and added to the configuration of the sensor.
