Trimble SX12 Laser Pointer White Paper 5
To handle this, each instrument is individually calibrated during the production process. This
individualized calibration is combined with tailored workflows in Trimble Access to ensure
confidence in your measurements and stake locations.
When operating in EDM Standard mode, the temperature calibration is taken into account and the
measurement accuracy when using the laser pointer for positioning is 2mm +/- 0.5mm. When
operating around 10°C ambient temperature, there is little deviation between the laser and EDM.
Likewise, when operating at close ranges, in typical working temperature, the deviation is extremely
small or insignificant.
Accurate and Dependable Results
The instrument and field software behaviour is tailored to ensure accurate and dependable results,
with a key consideration being whether the instrument is in Standard or Tracking mode.
The key points to remember are:
● The cross hairs in the video display in Trimble Access will always indicate where the
measurement is being taken to
● If you use the laser pointer with EDM in standard mode, then the measurement will always
be taken where the laser spot is positioned.
