Enhanced Alignment Procedure
A capability of the alignment command is called the Enhanced Alignment. The
Enhanced Alignment feature allows the user to perform an alignment quickly and
easily. The procedure is as follows:
1.
Select the lowest station number receiver selected (usually station 1).
2.
Issue the command A0<>. Sending this command prepares the system for
collection of alignment data (3 data points) and resets previous alignments by
sending the commands R1<>, R2<>, R3<>, and R4<>.
3.
Place the receiver at the proposed origin location and press P once.
4.
Move the receiver along the proposed positive X-axis from the origin and
place it about 18” to 24” from the transmitter and press P once.
5.
Move the receiver along the proposed positive Y-axis from the origin and
place it about 18” to 24” from the transmitter and press P once.
6.
The system then composes the alignment coordinates and prints the new
alignment parameters to the screen.
