Operator's Guide

thermal insulation carefully so that it does not touch the sensor

package.

12.Ensure that the sensor cable is loose and that it exits the

seismometer enclosure at the base of the instrument. This will

prevent vibrations from being inadvertently transmitted along

the cable.

2.8 Installing in pits

For outdoor installations, high-quality results can be obtained by

constructing a seismic pit.

Depending on the time and resources available, this type of

installation can suit all kinds of deployment, from rapid temporary

installations to medium-term telemetered stations.

Ideally, the sensor should rest directly on the bedrock for maximum

coupling to surface movements. However, if bedrock cannot be

reached, good results can be obtained by placing the sensor on a

granite pier on a bed of dry sand.
