so-
called “thick” side of each panel is covered with a polyethylene
neutron moderator. Both panels have
battery tubes; these are discussed in Section 1.3.2.2.
Both the Ranger and the Fission Meter panels are highly water- and dust-resistant, with respective ingress
protection ratings of IP67 and IP63.

CAUTION:
Place the two Fission Meter panels flat on the floor or other smooth, horizontal surface, with
the “thin” (
3
He tube) sides down. DO NOT stand them on end before they are connected together. DO NOT
allow them to fall over during assembly or use. This is a precision scientific instrument that must be
protected from shock.
1)
Connect the panels using the captured quick-connect pins and two (2) hinge links; see Figure 3.
2)
Connect the panels with the black, shielded cable,
taking care to correctly orient the connectors before
pushing and turning them
.
Do not apply excess force.
When correctly connected, the cable ends have an
IP63 ingress protection rating.
3)
Slide the padded carrying case onto each panel (if not already in place), and secure each with its hook-
and-loop closures.
4)
Connect the Trimble Ranger to the master Fission Meter panel with the 9 pin serial cable.
DANGER
High voltages are present inside the panel assembly casings.
Do not attempt to open the panel
housings. The only user-accessible/maintainable parts are the battery tube and cap, and the humidity
indicator/desiccant.
