Fastening Plate.
b. Standard Transducer
The standard transducer may be installed on a wall by itself or with the optional leveling plate.
Before installing the standard transducer, you must switch the position of the vertical and
transverse geophones. This positions the geophones to their natural axes compensating for the
vertical wall installation. This is a simple procedure requiring no special tools.
To switch the vertical and transverse geophones, remove the three screws on the top cover. Insert
a screwdriver into the slot on the side of the transducer and pry off the top cover. Remove the two
screws securing the electronics to expose two geophones. Switch the vertical and the transverse
geophones. Replace the electronics. Replace the top cover while maintaining the gasket’s position.
Align the cover with the screw holes and the center hole. Insert the three screws and tighten until
the cover, gasket, and housing press together. Finally, tighten the three screws in a clockwise
sequence to assure proper gasket seating. Tighten each screw to 10 lbf/in. (1.2 N.m) torque. A
proper seal occurs when the gasket begins to bulge out slightly from the transducer cover and
housing.
WARNING: Do not over-tighten the lid or the installation bolt. Over-tightening the lid may
damage the gasket and break the seal strip the screw hole threads, or cause
Sensorcheck failure.
