transmitter is located in the neck of the transmitter, behind the housing.
The vent path is 360° around the transmitter between the housing and sensor.
(See Figure 2.)
Keep the vent path free of any obstruction, including but not limited to paint,
dust, and lubrication by mounting the transmitter so that the process can drain
away.

2.0 Consider housing rotation

To improve field access to wiring or to better view the optional LCD display:
1. Loosen the housing rotation set screw.
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 screw.

3.0 Set jumpers and switches

3.1 Security
After the transmitter is configured, you may want to protect the configuration
data from unwarranted changes. Each transmitter is equipped with a security
jumper than can be positioned "ON" to prevent the accidental or deliberate
change of configuration data. The jumper is labeled "Security". The security
jumper also prevents changes made using the Local Operator Interface.
