The standard transmitter orientation is shown in dimensional
drawings found in this manual (see Figure 2-5). Use the
following procedure to rotate the electronics housing for
improved field access to wiring or the zero/span screws:
1. Loosen the housing rotation set screws.
2. First rotate the housing clockwise to the desired
location. If the desired location cannot be achieved
due to thread limit, rotate the housing counter
clockwise to the desired location (up to 360° from
thread limit).
3. Retighten the housing rotation set screws.
