• Ease of deployment through no mass lock, no mass centering and wide tilt range • Integrated web server for efficient instrument management Trillium Compact seismometers are available with 20 s or 120 s low corner period. The 20 s variants have a wide operational tilt range of ±10° and are suitable for downhole installations where the seismometer cannot be levelled, or for rapid deployments where a quick settling time is needed. - Page 12 For some studies, it may be preferable to use UVW mode instead of XYZ mode for recording seismic data. Trillium Compact is available in several variants to facilitate vault, surface, or buried downhole deployments: Model TC120-SV1 A surface vault seismometer in an aluminum enclosure with a •...

After delivering a Trillium Compact to its installation site, you can safely remove it from the packaging or carrying case and handle it without any special precautions other than taking care not to drop it or bang it against hard surfaces. Trillium Compact seismometers do not require any mass lock mechanisms or mass centring. - Page 14 Cable – Serial 16978–2M A cable that provides serial communications and power to communications the Trillium Compact.

Page 19: Chapter 2 Performing A Posthole Installation
A Trillium Compact Posthole seismometer may be installed in an uncased or cased hole. Units will self-level as long as the Trillium Compact Posthole is within ±2.5° for the 120 s model or ±10° for the 20 s model of vertical, making site preparation simple. -
Page 20: Aligning A Trillium Compact Posthole To North
The recommended practices for aligning a Trillium Compact Posthole vary based on the depth of the hole where the unit is installed. (1) For recommendations on aligning a Trillium Compact Posthole in a shallow hole of 2 m or less, see 2.2.1 “Using a Surface Line”... -
Page 21: Using A Surface Seismometer
You can use a seismometer installed at the surface to determine the orientation of the horizontal (X and Y) components of the Trillium Compact Posthole once installed in the hole. This method involves comparing the recorded output of both seismometers and computing the relative direction of seismic wave motion to determine the relative azimuth of the down-hole Trillium Compact Posthole compared to the surface seismometer. -
Page 22: Troubleshooting Your Installation
2.3 Troubleshooting Your Installation It is normal to see spikes in the horizontal channels of a Trillium Compact as the seismometer settles after installation. However, if these spikes do not diminish after a few days, there may be a problem with the installation and the site should be visited to determine the cause of the spikes. -

(2) For model numbers TC120-PH1 and TC20-PH1, the optional bubble level will be required and the optional adjustable locking feet kit may be required when performing a surface vault installation. -
Page 24: Choosing The Right Concrete
Insulate the seismometer to protect it from drafts and temperature change. To achieve optimal insulation of the seismometer, the following optional equipment is recommended: a Carrying Case / Insulating Cover (Nanometrics part number 16862). In addition, if you are 1.

Page 29: Theory And Practice Of Insulation
When the Trillium Compact is level, lock the feet by rotating each locking nut tightly against the seismometer base, while preventing the foot from turning. Insert an Allen key into one of the holes in the locking nut to act as a lever and help tighten the locking nut. - Page 30 For seismometers that are well temperature-compensated, such as the Trillium Compact, but are improperly installed, thermally induced tilt on the horizontal channels will be more significant than direct thermal sensitivity on the vertical channel. Furthermore, due to the natural convection of air, thermally induced tilt is even observable in sealed underground vaults where the temperature is very stable.

Page 33: Cut-Away Illustration Of A Trillium Compact In The Insulating Cover
Ensure that the insulating cover is centred on the centreline of the Trillium Compact 7. Gradually lower the insulating cover over the Trillium Compact, ensuring that the insulating cover does not touch the seismometer. Ensuring the cover does not touch the seismometer is important for keeping the seismometer level and aligned. -

Page 36: Chapter 4 Input And Output Signals
Input and Output Signals 4.1 UVW and XYZ Output Signals The Trillium Compact can be configured to output either XYZ or UVW signals. The “natural” output is UVW where the outputs represent the actual motion of the three sensor component masses. The “conventional” seismometer output is XYZ where the outputs represent horizontal and vertical motion. -
Page 37: Serial Rs-232 Communications
4.3 Digital Control Input Signals A Trillium Compact has two digital control input signals: UVW and CTRL. UVW changes the output mode (which is XYZ by default) to UVW mode. By default, CTRL enables the calibration function. You can reconfigure the CTRL control line to activate short period mode (the default is long period mode) instead. -
Page 38: Calibration Input Signal
±4 V, with an optimal output of 0 V. A maximum mass position output signal greater than ±3.5 V indicates that the Trillium Compact is no longer sufficiently level and may not be providing useful seismic signals. Should this occur, visit the installation site as soon as possible to level the unit. -
