3. Unscrew the remaining two mounting screws from the acquisition
module in the base enclosure and remove the acquisition board.
4. Place an insulating gasket on the meter body where the electronics
will be mounted (see gasket in Figure 1-5 ).
5. Place the base enclosure on top of the meter body on top of the
insulating gasket. Note that the transducer port openings on the
base enclosure are labeled with transducer locations (i.e., A1, A2, B1,
B2, C1, C2, D1, D2).
a) Orient the base so that the A1 transducer port is closest to the
A1 transducer location on the meter body. The meter body
has the transducer location labels embossed in the body next
to each transducer boss. The ports on the base enclosure
must be oriented outward (towards the sides of the meter
body, perpendicular to meter axis).
