1 Abbreviations and Conventions Bluetooth BTLE Bluetooth Low Energy wireless standard Universal Serial Bus PST 3 PiCUS Sonic Tomograph 3, name of the measurement system for sonic tomography PCA 3 PiCUS Calliper PRHD PiCUS Radio Hammer with Display, only usable with PiCUS Sonic Tomograph 3 Measurement point.
Page 4: Field Of Application / Disclaimer
Tomography and TreeTronic Resistance Tomography are suitable methods for measuring the remaining wall thickness in detailed tree examinations. The PiCUS Sonic Tomograph 3 was developed for the examination of standing trees during in-depth investigations. The use of the device on other objects may lead to damage to the device or the object being measured.
Page 5: Packing List
3 Packing list The PiCUS Calliper 3 (short PCA 3) is not part of the PiCUS Sonic Tomogrqaph 3 set (short PST 3) but is an optional accessory component. For a quick and convenient capture of tree geometry, the use of PCA 3 is recommended. It does not require a separate transport container and, instead, fits in the disassembled state inside the tomograph case.

4.3 Control elements of the PiCUS Sonic Tomograph 3 The PST 3 has three buttons for data entry and navigation in the menu. button, push the rotary knob (to the inside). Function: enter a menu or confirm a value. button Function: leaving a menu or skipping functions, if all settings were made.
Page 12: Bluetooth Address
Bluetooth Address : To link the PCA 3 with the PST 3, this Bluetooth address must be entered. The Bluetooth address of the callipers can be displayed in the Bluetooth manager of a Bluetooth-enabled PC or directly in the calliper. BT-Address can be displayed in the main menu of...

Page 14: Autonomous Operation
5 Autonomous Operation 5.1 General Workflow To create a sonic tomogram, the following steps are necessary: - Thorough visual inspection of the tree to decide whether and where the tomogram should be created. A much more detailed description can be found in the software manual vX.X_IML_Tree_Inspection_Manual_XX.pdf.
Page 15: Circular Tree Cross-Sections
5.2.1 Circular Tree Cross-Sections Sonic Tomogram Geo Circle In the menu of the PST 3, select the option. The submenus configure the circle and the distances of the sensors along the circumference. Number of MP : Enter the number of MP. The number of MP is the number of nails in the tree.
Page 16: Entering Tree Data
The PST 3 initiates the connection to the Calliper. When the connection is established, the first distance to be measured is displayed on the Calliper's screen. The PST 3 can be carried during the measurement to avoid BT shadowing behind the tree. If the Bluetooth connection is interrupted and there is no change on the Calliper's Enter display, the...

Page 18 Number : Enter a tree number if available. N/E/S/W Alignment : Enter the MP that is in the north of the tree. The default value is MP1 for north. The orientation is given as an angle in the PC program (deviation from MP1 in the north direction).

5.4 Installing the PiCUS Sonic Tomograph 3 on the Tree Once all the data has been entered, the device is attached to the tree. The blue strap in the case can be used to secure the device to the tree. All nails (measurement points) should have numbers.
Page 20: Example Of Using The Mp - Sensor Assignment Functions
5.4.1 Example of using the MP - Sensor Assignment Functions The tree has 14 MPs. The PST 3 is equipped with 12 sensors. Sensor-MP Allocation - Navigate to the Sensor 1 -> MP 1 - Select , i.e., sensors arranged section-wise. This first sensor-MP Position 1/2 assignment (called ) places Sensor 1 on MP 1, Sensor 2 on MP 2, and...
Page 21: Sonic Measurement
5.5 Sonic Measurement Before the actual acoustic measurement begins, make sure that all sensors are securely seated on the nail heads. Pulling the hammer cable may displace sensors from the nails. If the sensor assignment is correct and all sensors are properly seated on the nails, measurements can proceed.
Page 22: Point To Point Measurement
Note: If the hammer is operated in wireless mode, the Large hammer antenna should be kept as far away from the sensor cable harness as possible. This prevents distance interference signals from coupling into the sensor lines. For example, the hammer can be held vertically to achieve this.
Page 23: Point To Point
Point to Point Select from the main menu. To measure the velocities, the following inputs need to be made: Circumference Diameter : The distance between the measurement points. Either the distance along the circumference is entered (assuming a circular tree cross-section, measured with a tape measure around the tree), or the distance between the knocking point and the measurement points is directly determined (e.g., with PCA 3).

Page 27: Reading Gps Coordinates From The Picus Sonic Tomograph 3
6.2 Reading GPS Coordinates from the PiCUS Sonic Tomograph 3 The PST 3 has a built-in GPS receiver that is activated when the device starts up. In standalone mode, GPS coordinates are automatically saved in every file on the internal SD card of the PST 3.
Page 28: Charging The Picus Sonic Tomograph 3
7 Charging the PiCUS Sonic Tomograph 3 To charge the device, the hammer, control unit, and charger must be connected as shown in the illustration. Charge LED in the Hammer Display Charge Charge LED on the PST 3 lights up until the charging process is complete.
Page 29: Radio Hammer Operation
8 Radio Hammer Operation The electronic hammer (PRHD) can be connected to the PST 3 via a cable or wirelessly through a radio connection. The cable connection is more secure. In wireless mode, a public frequency is used. For this reason, especially in cities, the signal transmission between the hammer and the PST 3 can be disrupted.

However, battery lifespan greatly depends on usage and environmental conditions. Sensor calibration is not required. However, if needed, we can provide calibration certificates from our laboratories to meet ISO 9000 requirements. Please contact our service department for further information (contact@iml-electronic.de).
Page 33: Accessories
12.1 Accessories Standard roofing nails can be used to attach the acoustic sensors to the wood of the tree. The nail length should be sufficient to penetrate the bark. The diameter of the nail head should be between 6 and 10 mm. The surface of the nail head should be flat to ensure good contact with the magnet.
