Locating

 

In summary, the three locations mentioned above are as follows: the rear negative locate point (RNLP), behind the transmitter; the positive locate line, above the transmitter; and the front negative locate point (FNLP), ahead of the transmitter. The RNLP and the FNLP show the position and lateral orientation of the transmitter.

Using Plus/Minus Indicators for Locating

The “+” and “–” signs indicate the direction to move the receiver to locate the transmitter. The “+” sign means move the receiver forward, and the “–” sign means move it backward.

Plus “+” = Move Forward

Locating the Transmitter from the Drill

The procedure for locating the transmitter starting at the drill is given below. A similar procedure can also be used to locate the transmitter from the front, facing toward the drill (see “Locating the Transmitter from the Front” later in this section).

Finding the Rear Negative Locate Point (RNLP)

1.With the trigger held in, walk toward the transmitter; the signal strength in the top left window will increase. Observe the point at which the “+” sign in the top left window changes to a “–” sign. This is the RNLP. Move the receiver forward and backward a little until the exact location can be identified where the “+/–” signs flip from one to the other. This is the approximate longitudinal (fore/aft) position of the RNLP.
