Since the highest measuring sensitivity is directly around the rods or the access tube, the TRIME-FM would measure too low values, if there was an air gap. In water saturated soils the measured values would be too high.
1.1.9 PC-Connection via RS232 The TRIME-FM can be connected to a PC via the RS232 connector and the appropriate cable, in order to carry out data logging, changing the operating mode, or calibration. As long as the PC is connected the power-off automatic is disabled to prevent switching off.

Preparation Rods For the protection of the rod tips it is necessary to use the preparation rods for probe P2, P2Z, P2G and P3. A defect and blank rod is sensitive against electrostatic charge and can destroy the electronic!
Mounting of Spare Rods with O-ring Seals 4) put silicon grease to the threads of the rods (new spare rod are greased at works) 1) prepare probe body, seals, rods 5) screw the rods into the probe body 2) put the seals into the borings 3) push the seals to the basis of the borings where the threads begin...
The TRIME-T3 Tube Access Probe Introduction The measuring of soil water content with Time Domain Reflectometry is now a well established method. However water content profiling is not possible with conventional TDR rod probes. The TRIME tube probe was developed for this reason. Since 1994 the TRIME-T3 has found numerous applications in earth and environmental sciences, fulfilling even the most exacting requirements.
Note that the necessity of a close contact between access tube and material is vital for reliable measurements and that the tubes should be installed by our recommended method. • For example at an assumed water content of 15 vol. % an air gap of 1 mm around the whole length of the tube would result in an underestimation of 1 - 2 vol.

Some materials, especially very clayey soils and soils with high organic contents, can afford material specific calibrations due to their different dielectric behaviour.
The IMKO auger equipment consists of: access tube support pillar with three soil anchors, ramming head with clamp device, screw auger with handle, clamp device for the rubber bung, and an internal steel guide/protection tube.
Instructions for Access Tube Installation The following instructions should be taken account of: The ramming head, the TECANAT access tube and the internal steel guide and protection tube are one unit. Ramming Head The internal protection tube has to lie on with Clamp Device the cutting shoe of the access tube, Fixation-...
Inserting T3 into the TECANAT tube When you are going to work with your TRIME-T3 tube access probe: Press the spring mounted wave-guides to the probe body when you insert the T3 probe into the tube! Thereby you avoid ripping off the spring mounted wave-guides. TECANAT plastic tube Please note Should you use new T3 probes (eight wave-guiding plates instead of two) in old GFK tubes, we advice...
You would have to send instruments and probes to us in any of the above cases where basic alignment is required if you have no calibration set. IMKO will charge calibration costs. Moreover you will save the forwarding charges and you will not have to interrupt your measuring campaign, if you calibrate by yourself.
START button to switch on the instrument. After this „dummy measurement“ is finished, you can plug in the calibration connector at the side of the TRIME-FM. The display shows the first reference value of dry glass beads for the appropriate probe (e.g. 2,8%). The probe cable must now be unwound and spread out in a way that the cable doesn't touch itself.

Operation The charger starts charging automatically as soon as a battery pack is installed and the charger is plugged in. Usually, the battery packs are brought into contact by the plugs which are enclosed the supply. If the red LED after the test phase (about 10 seconds) still keeps flashing, check the polarity of the battery pack.
