Short answer: The TotaLite Sensor doesn’t measure the distance to targets.
Explanation: The TotaLite Sensor doesn’t perceive depth, as all measurements are taken as two-dimensional images. To account for the distance between the device and the target (the “slope distance”), the user must measure that distance during installation and enter it into the platform when prompted during baseline setup. The most accurate way to measure the distance is to use a total station during installation—by “shooting” the targets individually and the TotaLite device.
