Installing the 3ESP
8.
Connect the sensor to the breakout box or a Güralp digitizer if you are using
one.
9.
Connect a 12 V power supply either directly or through the breakout box or
digitizer.
10.
If your 3ESP instrument has the standard, manual mass control system,
three
sockets on the casing of the 3ESP allow each mass to be locked and unlocked.
Locate the socket corresponding to the vertical sensor mass.
Otherwise
, skip to step 16.
Remove the pressure cap from the socket.
11.
Carefully insert a 3 mm hex driver into the casing, allowing it to be guided into
the conical socket on the sensor housing within. The inner sockets are not
precisely aligned with the holes in the casing, since their position is
determined by the fixed component. Use the diagram below to help you locate
the socket.
