MODEL 5503-2M & 5503-3M: GROUNDING
Before operating the
Model 5503-2M or
Model 5503-3M, verify that
the ground contact foot on
the load box and balun box
is attached to ground, and is
grounded. This can be
accomplished by using bolts
(not included) that screw
onto the ground plane in the
shielded room.
