FAQ Calliper

How important is the exact geometry?
Velocity calculation are based on the formula Velocity = distance / time The more accurate the geometry of the measuring level is, the more accurate the tomograms are. The PiCUS software offers a number of functions to measure the geometry efficiently. The triangulation – method is most accurate.
Do I need the electronic calliper?
The electronic calliper is a very efficient tool to measure the positions of the measuring points. Within a few minutes even complex geometries are recorded. Mechanical standard callipers can also be used.
Do the instruments require annual service?
No. Sensors do not need regular calibration. But argus offers check-up - service for ISO9000 reasons etc.
Do I need training to operate the PiCUS?
Yes. Training on the instruments is highly recommended. The recommended training takes 1 or 2 days.
What are the recommended configurations for my PiCUS system?
Because of the electronic hammer the number of sonic sensors is not that important any more. The combination of the sonic tomogram and the electric impedance tomogram does give more information about most of the trees than just many measuring points. It is useful to consider to acquire a “smaller” PiCUS AND the Treetronic rather than a “large” PiCUS (12 to 16 sensors).
