2.1 Unpacking and packing
The 3TB seismometer is delivered in a single transportation case, with
the sensor system and hole lock mechanism (if ordered) packed

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, in sections;
•
a cable to join the sensor to the breakout box;

the breakout box;
•
the hole lock control unit;

a cable strain relief mechanism;
•

•
a calibration data sheet.
The sensor is securely packed, and you will need to remove most of
