REX Meter
Technical Manual 2 Product Description
Figure 2-4. Exploded view of the REX meter
Meter Cover
The meter cover of the REX meter is a polycarbonate housing designed to
protect the inner assemblies of the meter. The ultraviolet (UV) stabilized
polycarbonate cover reflects solar radiation, resulting in minimized discoloration
and reduced internal heating. The gray polycarbonate side walls of the meter
cover reduce the internal temperature rise caused by sun loading, which may
extend the life of the electronic components. The cover has a clear plastic
window that allows the meter LCD to be viewed.
Removing the cover reveals the inner housing.
Nameplate
The nameplate is mounted on the inner housing. The nameplate identifies
important information about the meter. For more information on the nameplate,
see Appendix C, “Nameplate Information.”
Inner Housing
The polycarbonate inner housing is designed to provide extra protection to the
electronic components and to allow the REX meter to be safely handled when
the meter cover is removed.
Removing the inner housing reveals the main circuit board, option boards, circuit
board support frame, and meter base.
