2.1.2 INSTALLATION METHODS
This section explains installation methods METER recommends for different soil
conditions (Figure1).
The TEROS 54 probe can only be installed in very loose, sandy, and soft soils without the
TEROS54 auger.
METER recommends using the TEROS 54 auger and slide hammer that are designed
specifically for installing the TEROS 54 in compact, firm soil. This method will result in good
soil contact.
• The TEROS 54 auger is shaped to prevent soil compaction near the probe elements
(Figure2).
• The slide hammer (Figure3) consists of four parts: handle, rod, weight (approx. 4 kg
[8.82 lbs]) and connector (put on the TEROS 54 head). Because there is a predetermined
distance that the slide hammer weight travels when dropped, there is an even distribution
of force delivered.
