Three Methods to Verify Depth Reading

Disable HAG, set the receiver on the ground, and take another depth reading. This

reading should be within 5% of the depth reading obtained with the HAG on and the

receiver lifted. In the prior example, the reading should be 2.62 m.

With HAG on, set the receiver on the ground and add the HAG to the depth shown. It

should also be 2.62 m.

If HAG is not being used, note the depth on the ground and then raise the receiver

exactly 1 m. The depth reading should increase this same distance. In the example

above, the depth would be 3.62 m.

See Appendix C on page 67 and Appendix D on page 71 for more information on depth.
