Setting up the CMG-6TC
3.1
Introduction
The CMG-6TC is delivered in a single transportation case. The
packaging is specifically designed and should be reused whenever
you need to transport the instrument.
Note any damage to the packaging when you receive the equipment
and then unpack, ensuring the following are present:
•
The seismometer;
•
The thermal insulation jacket;
•
The calibration and installation sheet.
•
The connection cable (which contains a DC-DC power converter);
and
•
The attachable North/South alignment tool, if ordered
The instrument is factory set to the customer-specified response
mode. To change the response mode before deployment, carry out the
procedure detailed in section 4 on page 8.
3.2
Handling notes
•
Avoid bumping or jolting the instrument when handling or
unpacking.
•
Do not kink or walk on the cables (especially on rough surfaces
such as gravel) or allow any cable to bear the weight of the
instrument.
•
Do not connect the instrument to power sources, except where
instructed.
•
Do not ground any of the signal lines from the sensors.
3.3
Deployment
Note: Refer to Appendix A on page 13 for information on
connector pin-outs.
1.
Stand the instrument on bedrock where possible or, at least,
deep in well-compacted subsoil. Remove all loose material from
the mounting surface as this will ensure good contact between
the instrument and the surface.
