22 +* Bury seismometers at an appropriate depth for noise reduction and stable ground coupling, typically 0.5-0.8 metre depth.
23 23  * Orient the sensors correctly using a compass, paying special attention to the north direction. When using a compass to orient the sensors, ensure it is kept away from metal objects or structures that could interfere with its magnetic field. Accurately determine the north direction for precise sensor orientation.
24 +* Ensure the sensor is leveled correctly. A paver or concrete slab can be used to allow for more accurate leveling.
25 +* It is recommended that the following sensors be installed with a PVC tube covering to prevent corrosion and other environmental degradation:
26 +** TC-120
27 +** TC-20

29 +* Hold the sensor or sensor covering securely while infilling and packing the hole to ensure the sensor is kept level.
