The tree static pulling test is so far the only method that allows conclusions to be drawn on uprooting and breaking safety in equal measure. The PiCUS TreeQinetic measuring instruments are optimized for such pulling tests and provide the necessary data basis for safety calculations.
PiCUS TreeQinetic Manual 3.2 Designated Application The PiCUS TreeQinetic System is intended for use as measuring instrument in tree static pulling tests. In the pulling test, the tree under investigation is subjected to a measured load in a controlled manner using a pulling rope, while the reaction of the trunk and roots to this load is recorded.

PiCUS TreeQinetic Manual 4 Measuring Instruments 4.1 Description of System Components This chapter gives an overview of the components, structure and functions of PiCUS TreeQinetic. 4.1.1 Communication Unit The PTQ communication unit (abr. com unit) is the central part of the system. It sends command signals to the sensor moduls, receives measuring data from them and forwards the data to the PC or mobile device.
Page 9
PiCUS TreeQinetic Manual Operation The com unit is switched on or off by briefly holding the on/off switch. After starting, the display shows device information and the serial number. After a device search has been carried out, the display lists the connected modules in order of device type.
PiCUS TreeQinetic Manual 4.1.2 Forcemeter The Forcemeter is mounted on the rope to measure the force exerted on the tree. Explanation of Parts No. Designation Function • Attachment eyes Attachment points for shackles. Use with delivered iron shackles only! •...
PiCUS TreeQinetic Manual Mounting To attach the forcemeter one of the steel shackles supplied is attached to each side. The bolt is inserted into the hole of the forcemeter housing. The screwed-on spacer rings centre the forcemeter, they are not designed for taking up loads.

PiCUS TreeQinetic Manual Mounting Inclinometers are connected to the magnet of an inclinometer mount using the ball on the back. The infinitely adjustable guide of the ball allows the inclinometer to be precisely aligned before measurement. That means the front side with the display is flat horizontal while X and Y value display zero with minor decimals.
PiCUS TreeQinetic Manual 4.1.4 Elastometer The PTQ Elastometer measures the change in the length of the wood fibres to which it is connected. This change in length can be positive (elongation or strain) or negative (compression). Explanation of Parts No. Designation Function •...
Page 15
PiCUS TreeQinetic Manual Montage To attach an elastometer to the tree, you need a pair of elastometer needles, the needle gauge and a hammer. The needles are inserted into the gauge so that the tips point away from the handle and towards the tree.
PiCUS TreeQinetic Manual 4.1.5 Overlaod Indicator The PTQ overload indicator clearly warns by means of optical and acoustic signals when the measured values reach and exceed the given limits. Explanation of Parts No. Designation Function • Flashing lights Optical warning •...
Backup for transmission to PC Table 8 – Delivered cables and their applications 4.1.7 Case The PiCUS TreeQinetic system is supplied in a practical instrument case in which suitable holders are provided for all sensitive components. The inclinometer holders are located in the lid.
PiCUS TreeQinetic Manual 4.1.8 Eightfold Charger (Optional) As an optional accessory for extended TreeQinetic systems, the eightfold charger is available. This is primarily intended to charge up to eight PTQ modules simultaneously. However, this device can also be used as a distributor for data cables during the measurement.
PiCUS TreeQinetic Manual 4.1.9 Anemometer (Optional) Wind meter for use with the PiCUS TreeQinetic. If instead of the usual pulling test, the effect of the wind on the tree is to be investigated, this anemometer is used to determine the wind parameters while inclinometer and elastometer record the reaction of the tree.
4.2 General Operating Instructions 4.2.1 Ambient Conditions The PiCUS TreeQinetic System is designed for measurements under field conditions, but when using these highly sensitive instruments, the ambient conditions should be considered. The intended temperature range is 0 - 40 °C.
PiCUS TreeQinetic Manual 4.2.3 Automatic switch-off In order to save energy by unintentional switch-on, the devices switch off automatically after a certain time without key operation and communication. This is the case after 30 minutes for com unit and sensor modules. The forcemeter switches itself off after 60 minutes.
4.2.5 Maintenance Maintenance work is to be carried out solely and exclusively by the workshop of argus electronic GmbH at the company headquarters. Opening the devices voids all warranty and can cause damage to the respective devices.
