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 11 ft. 6 in.
or
With HAG on, set the receiver on the ground and add the HAG to the depth shown. It
should also be 11 ft. 6 in.
or
If HAG is not being used, note the depth on the ground and then raise the receiver
exactly 3 ft. The depth reading should increase this same distance. In the example
above, the depth would be 14 ft. 6 in.
See Appendix C on page 77 and Appendix D on page 82 for more information on depth.
