Unpacking
The 3T seismometer is delivered in a single transportation case. The
packaging is specifically designed for the 3T 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. The package should contain:
•
the seismometer;
•
a cable to join the sensor to the breakout box;
•
the breakout box (which provides separate connections for the
signal, control and power lines);
•
a Hand-held Control Unit (HCU) for monitoring sensor outputs
and calibration, if ordered;
•
a 10-pin connector for your power lead (see below); and
•
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,
•
a multi-pole socket for input and output,
•
other optional connectors as ordered;
•
a bubble level,
•
an air vent port,
•
three adjustable feet, and
•
two accurate orientation pins (one brass and one steel).
