The Leica vPole has three preset height positions that the iCON iCS50 recognizes automatically using printed stripe patterns on the pole. This eliminates the need to manually enter pole height during measurement.
| Position | Height (Sphere Center) |
|---|---|
| H1 | 1.500 m / 4.922 ft |
| H2 | 2.000 m / 6.562 ft |
| H3 | 0.240 m / 0.787 ft |
Each position is identified by a unique pattern of three printed stripes on the pole shaft. The iCS reads these stripes visually to determine the current pole height automatically.
Automatic height detection requires the instrument to be at least 2.5 m / 8.2 ft away from the vPole. At shorter distances, height detection will not function and the pole height must be entered manually.
The vSphere can be mounted on either the top or bottom of the pole using the 5/8" thread, allowing for both standard upright and reversed (inverted) measurement configurations.
Accuracy varies by pole height and distance. The following is for the iCS50 with the vPole option (tilt compensation included):
| Distance | H1 (1.5 m) | H2 (2.0 m) | H3 (0.24 m) |
|---|---|---|---|
| 10 m | 2.0 mm | 3.0 mm | 1.0 mm |
| 30 m | 5.0 mm | 6.0 mm | 2.0 mm |
| 50 m | 8.0 mm | 10.0 mm | 3.0 mm |
