Operator's guide
•
Keep the sonde sections vertical wherever possible. Carry them
by hand and store in a safe rack. Never drag or roll the sonde.
•
Never lay the sonde horizontally whilst the sensors are unlocked.
If the sensor system topples over, you must inform Güralp
Systems.
•
Keep all the parts of the sensor system protected and clean so that
they can be joined together securely. Store in the original
packaging if possible.
•
Do not kink or walk on the data cable (especially on rough
surfaces such as gravel), nor allow it to bear the weight of the
sensor.
•
Do not connect the instrument to power sources except where
instructed.
2.3 Assembling the 3V
The 3V is delivered in separate sections, which need to be assembled
before the instrument can be installed in a borehole. It is recommended
that you perform these steps with the help of at least one other person.
Important:
Make sure your environment is clean and dust free before
assembling the unit. Stray fbres o r p articles c ause d amage t o t he
“O”-ring seals between the components and may render the sensor
unusable. Do not remove the protective caps on the ends of each unit
until you are ready.
1. Ensure that the top surface of the hole lock and the base of the
sensor are clean.
2. Carefully lif the sensor, and connect the cable from the hole lock
to the connector on the sensor base.
3. Gently lower the sensor onto the hole lock, making sure that it is
properly aligned and no wires are trapped beneath the base.
4. Using the cap head screw provided, fasten the sensor base onto
the hole lock.
