Removal of the Electronics Housing from the Baseplate

In rare instances, it may be necessary to access the inner electronics of the Focus meter. To remove

the Electronics Housing from the baseplate, set meter on a solid surface and place hands around the

bottom of the gray housing where it meets with the baseplate. With thumbs in the 6 o’clock position,

while touching both the housing and baseplate, squeeze firmly with thumbs using considerable force, to

flex the housing and release the bottom two fasteners located at the 4 o’clock and 8 o’clock positions.

It may be necessary to alternate pressure by thumbs until both fasteners are released. Once these two

fasteners are released, push gently toward the 12 o’clock position to release the top two fasteners. The

housing can be lifted off and then the current input connector can be unplugged from the printed circuit

board in the housing assembly. Extra care should be given to lift the housing straight off of the

baseplate to avoid damaging the spring contacts located on the base assembly. Spring contacts should

be visually inspected to ensure symmetry with one another.

Figure 7 – Removal of Electronics Housing

Installation of the Electronics Housing onto the Baseplate

Before installing the Electronics Module onto the Baseplate, make sure that the Electronics Module and

Baseplate are free of foreign debris and that any cables are properly routed to prevent interference with

the meter’s electrical connectors. Attach current input lead connector onto mating connector on printed

circuit board. Line up the 4 slots in the gray electronics housing with the 4 mating snap-on protrusions

located on the black baseplate. Once aligned, apply gentle force to snap the two assemblies together.

Sealing the Meter

The

FOCUS

meter comes standard with T-seal provision. To gain access to the inside of the meter,

the T-seal must be removed (broken). Factory T-seals have unique markings. Many utilities likewise

have T-seals with a unique signature. A missing or broken T-seal on a meter in a field installation can

be an indicator that someone has gained access to the internal meter (unauthorized access). It is also

desirable that the original factory T-seal remains intact. In the case of warranty considerations, a

factory T-seal in place does validate the meter has not been altered. If re-sealing is desired, T-seals

can be installed through the

FOCUS

cover and baseplate assembly.
