CMG-3ESP

Seismometer

Installation

Check you have all components and cables.

! CMG-3ESP weak motion broadband seismometer

! Thick grey signal cable

! Sensor calibration data booklet

You will need a suitable digitizer or recording equipment,

and a 12–24 V DC power supply.

For pit or posthole installations, follow the steps

overleaf.

Choose a suitable site to install the sensor.

The sensor should be mounted

- at, or ideally below, ground level

- away from sources of natural noise (e.g. wind, surf)

- away from sources of cultural noise (e.g. traffic)

- in contact with bedrock, if possible

- otherwise, on a hard granite or concrete pier

- in an environment with constant temperature

shielded from air currents (e.g. in a polystyrene box)

- away from electrical cables and appliances

Connect your digitizer or recording equipment according to

the directions supplied.

Loosen the brass locking nut on one of the adjustable feet.

Turn the foot, screwing it in or out to level the sensor. Check

using the spirit level on the sensor lid.

Repeat with the other adjustable feet, until the bubble in

the spirit level lies entirely within the inner circle.

Remove the screw cap protecting the vertical lock access

socket, and insert an Allen key. Find the retaining screw

within, and loosen it to unlock the vertical component.

Repeat for the north/south and east/west components.

Do not allow the instrument to tilt by more than 10° with

the masses unlocked.
