Measuring range and bearing between two targets
The procedure which follows shows how to measure the range and bearing betw-
een target
's origin (cursor) on the center of target
's
origin shifts to cursor.
4. Press the [EBL/VRM CONTROL] key.
5. Press the onmipad to bisect target
"A" and target "B" in Figure 2-11.
1. Press the omnipad to place EBL1 "A".
2. Press the [EBL/VRM SELECT] key to choose EBL1 readout and then press the
[EBL/VRM CONTROL] key.
3. Select EBL OFFSET on the menu and press the [ACQ/ENTER] key. EBL1
"B" with EBL1. Check the EBL1 readout to
find the bearing between target "A" and target "B".
6. Press the [EBL/VRM SELECT] key to choose VRM1 readout. Press the omnip-
ad to place the outside edge of VRM1 on the inside edge of target "B". Check the
VRM1 readout to find the range between target "A" and target "B".
7. To cancel, select EBL OFFSET on the menu and press the [ACQ/ENTER] key.
