Guralp Systems CMG-5T Installation - Manual (Page 2)

Installation
After installing, you will need to zero the sensor outputs.
This is most easily done through a Güralp digitizer.
Connect the sensor’s output port to the digitizer, and
power them up. Connect the digitizer’s serial output to a
PC.
Start the PC and run Scream!. Choose File > Setup...
from the main menu and view the Com Ports tab.
Set the Baud Rate to the correct value and click OK.
Loosen the brass locking nut on one of the adjustable
feet.
Turn the foot, screwing it in or out to level the sensor.
Check using the spirit level on the sensor lid.
Tighten the brass locking nut upwards to secure the
foot.
Repeat with the other adjustable foor, until the bubble in
the spirit level lies entirely within the inner circle.
Remove the screw-on cap protecting the offset adjusters.
With a small screwdriver, adjust each offset until the corresponding output is close to zero.
Zoom in as necessary.
Replace the pressure cap. The sensor is now ready for use.
Please refer to the full manual for detailed usage instructions, calibration and
troubleshooting.
