Note
：
For KTS-442UT series Total Station, Measuring to strongly reflecting targets such as to traffic lights in infrared
mode should be avoided. The measured distances may be wrong or inaccurate
When the [MEASURE] key is triggered, the EDM measures the object which is in the beam path at that moment.
If e.g. people, cars, animals, swaying branches, etc. cross the laser beam while a measurement is being taken, a
fraction of the laser beam is reflected and may lead to incorrect distance values.
Avoid interrupting the measuring beam while taking reflectorless measurements or measurements using
reflective foils.
Reflectorless EDM
●Ensure that the laser beams cannot be reflected by any object nearby with high reflectivity.
●When a distance measurement is triggered, the EDM measures to the object which is in the beam path at that
moment. In case of temporary obstruction (e.g. a passing vehicle, heavy rain, snow, frog, etc.), the EDM may
measure to the obstruction.
●When measuring longer distance, any divergence of the red laser beam from the line of sight might lead to less
accurate measurements. This is because the laser beam might not be reflected from the point at which the
crosshairs are pointing. Therefore, it is recommended to verify that the R-laser is well collimated with the telescope
line of sight. (Please refer to “24.11 REFLECTORLESS EDM”)
●Do not collimate the same target with 2 total stations simultaneously.
Red Laser Distance Measurement Cooperated with Reflective Foils.
The visible red laser beam can also be used to measure to reflective foils. To guarantee the accuracy the red laser
beam must be perpendicular to the reflector foil and it must be well adjusted (refer to “24.11 REFLECTORLESS
EDM”).
Make sure the additive constant belongs to the selected target (reflector) has been input on total station.
