Compatible with Disto X6
Enables P2P measurements with the device
The technology of the Leica DST 360 Adapter
The technology used comes from Leica Geosystems. Using innovative, sophisticated, and compact sensors, angles can be determined with an accuracy of ± 0.1°. Since the sensors operate passively, i.e., with virtually no energy consumption, power is supplied via gold-plated spring contacts from the Leica DISTO. This means that there is no need to change the batteries in the sensor separately, and the number of possible measurements with the Leica DISTO is hardly affected by its use on the Leica DST 360 adapter. The measurement information from the Leica DST 360 adapter is also communicated via these same contacts. The liquid level integrated into the base is used to roughly level the adapter first. Precise leveling relevant for the measurement is carried out using the tilt sensor integrated in the Leica DISTO. By determining the measurement plane by rotating the system twice, accurate calibration is achieved during the leveling process.
The mechanical multiple mount on the DISTO device and the torque-limiting locking screw (the screw screws through if tightened too much) ensure that only minor deviations can occur due to the mechanical mount. The adapter is made of cast aluminum, which is particularly stable over its service life—even with frequent use. Since precise targeting of measuring points naturally has a direct impact on accuracy, the Leica DST 360 has horizontal and vertical fine drives. A slip clutch enables quick targeting by turning by hand, whereas fine drives can then be used for precise targeting. This means optimum user-friendliness.
The basic principle with the measuring sensors and the tilt sensor is also used in the Leica DISTO S910. Here, however, it takes the form of a fold-out foot (Smartbase), which can be screwed onto a purely mechanical adapter, which then guides the device mechanically when aiming.
Accuracy
From a purely technical point of view, the accuracy of a point-to-point (P2P) measurement depends essentially on the accuracy of the distance meter and the horizontal and vertical angle sensors. Since the tilt sensor in the Leica DISTO is calibrated during the leveling process, this can be virtually disregarded. This results in a typical deviation of 5 mm for a P2P measurement over a measuring distance of 5 m. This deviation then increases proportionally with distance. We are talking about typical accuracy, i.e., this deviation can usually occur in most measurements *).
However, targeting and the geometric arrangement of measuring points are also particularly important when performing P2P measurements. Deviations in targeting naturally have a direct impact on accuracy. It is worth checking the position of the laser point by maximizing the magnification of the digital viewfinder or even by approaching the measuring point. It is also definitely advantageous for the laser point to hit the target at a right angle. If the laser hits the target object at a flatter angle, the possible measurement deviation also increases. This is easy to imagine if you slightly adjust the laser using the fine adjustment wheel. If I measure at an angle to a wall, the laser point moves significantly further from the actual measuring point than if I aim at a target object at a right angle. Accordingly, the possible deviation of ± 0.1° per sensor is much more noticeable! It is easy to imagine what this means for the result.
With the Leica DISTO S910, the P2P adapter is integrated into the housing, but the compact design achieves the same accuracy as the design with an external adapter.
