2.1 Handling notes
Although the 6T has a rugged design, it is still a sensitive instrument,
and can be damaged if mishandled. If you are at all unsure about the
handling or installation of the sensor, you should contact Güralp
Systems for assistance.
•
Avoid bumping or jolting the seismometer when handling or
unpacking.
•
Do not kink or walk on the data cable (especially on rough
surfaces such as gravel), nor allow it to bear the weight of the
sensor.
•
Do not connect the instrument to power sources except where
instructed.
•
Do not ground any of the signal lines from the sensor.
All parts of the 6T are waterproof.
2.2 Unpacking
The 6T seismometer is delivered in a single transportation case. The
packaging is specifically designed for the 6T and should be reused
whenever you need to transport the sensor. Please note any damage to
the packaging when you receive the equipment, and unpack on a safe,
clean surface. For each instrument in the packaging, you should have
received:
•
the seismometer;
•
the breakout box (which provides separate connections for the
signal, control and power lines);
•
a data cable, for connecting the instrument to a Güralp digitiser,
such as the CMG_DM24;
•
a calibration and installation sheet.
Assuming all the parts are present, stand the seismometer in the centre
of a bench and identify its external features:

a handle with North indication,
