4) Next, connect the threaded staff adaptors parts to the top of one staff section
and the bottom of another staff section as shown in Figure 13 a. The bottom
sensor is configured with opposing mounting points and the adaptors should
be screwed into one set of these mounting points as shown in Figure 13 b.

5) The separation between gradiometer sensors is determined by the lengths and
number of the staff sections linking the sensors. The minimum separation will
always include one of the threaded adaptors and the top (threaded) staff
section as shown in Figure 14 a. Typical sensor separation will be two staff
sections (4ft.). Note that Figure 14a shows only one staff section separating
the sensors. Normally, two staff sections will support the bottom sensor so
that the top sensor is at 8 ft and the lower sensor at 4 ft. An alternative
configuration is shown in Figure 14b where three staff sections support the
lower sensor. With any gradiometer configuration it is best to hold the staff at
arms length when measuring the gradient. This will prevent the lower sensor
from coming too close to the console and better isolate it from the magnetic
effects of the system circuitry and batteries.

6) The sensor cables may now be connected to the Remote Start Switch box, and
the Remote Start Switch may be connected to the G-856AX front panel
connector. As shown in Figure 15, attach the Velcro strip to the top of the G-
856AX black front panel bezel. Mount the Remote Start box to this mating
Velcro strip.
