3.1 Unpacking and packing
The 3TB seismometer is delivered in a single transportation case, with the sensor
system and hole lock mechanism (if ordered) packed separately. The packaging is
specifically designed for the 3TB 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 clean surface.
The package should contain:
•
the seismometer;
•
a cable to join the sensor to the breakout box;
•
the breakout box;
•
the hole lock control unit (optional);
•
a cable strain relief mechanism or combined cable strain relief mechanism
and surge suppressor;
•
a Hand-held Control Unit (HCU) for monitoring sensor outputs and
calibration, if ordered; and
•
a calibration data sheet.
The sensor is securely packed, and you will need to remove most of the foam packing
before it can be removed.
3TBs used to be delivered in sections which had to be assembled by the user. They
are now shipped complete and no assembly is required. If you are working with a
disassembled unit and need assembly instruction, please contact
[email protected] for an earlier version of this manual. If you need to transport a
unit but the packaging you have requires disassembly of the instrument, please
contact [email protected] for an up-to-date shipping container.
3.2 Handling notes
The 3TB is a sensitive instrument, and is easily damaged if mishandled. It will not
stand vertically upwards without support, and should not be operated until it has
been securely installed in a borehole casing. If you are at all unsure about the
handling or installation of the device, you should contact Güralp Systems for
assistance.
•
Do not bump or jolt any part of the sensor when handling or unpacking.
