Achieving perfect levelness isn't always essential for precise measurements when using iMapper.
A slight deviation, such as measuring 3 meters away with a 10 cm dip, introduces a minimal error— approximately 1.7 mm, which is often negligible.
This principle applies variably across different distances, demonstrating that minor inaccuracies can be acceptable depending on the context.
| a (cm) | b (cm) | c (cm) | error (cm) |
|---|---|---|---|
| 300 | 10 | 300.2 | 0.2 = 2mm |
| 500 | 10 | 500.1 | 0.1 = 1mm |
| 1000 | 10 | 1000.0 | 0.0 |

Nonetheless, it's crucial to note that in specific scenarios, like measuring against a non-vertical surface in an attic, the error margin can significantly increase due to the added complexity of the sloped angle.
This emphasizes the importance of understanding the impact of environmental factors on measurement accuracy in iMapper applications.
