1. If the transmitter is installed, secure the loop and remove power.
2. Remove the housing cover opposite the field terminal side.
3. Locate the jumper on the electronics board (see Figure 2-1), then
move the jumper to the desired setting.
4. Reattach the transmitter cover. To avoid condensation, metal to metal
contact is preferred.
5. If the transmitter is installed, reapply power.

Security
After configuring the transmitter, you may want to protect the configuration
data from unwarranted changes. Each transmitter is equipped with a security
jumper that can be positioned “ON” to prevent the accidental or deliberate
change of configuration data. The jumper is located on the front side of the
electronics module and is labeled SECURITY (see Figure 2-1).
Simulate
The simulate jumper is used in conjunction with the Analog Input (AI) function
block. This switch is used to simulate the measurement and is used as a
lock-out feature for the AI function block. To enable the simulate feature,
insert the jumper across “ENABLE” (see Figure 2-1) while the transmitter is
powered.
NOTE
When power is cycled to the transmitter, simulate is automatically disabled
regardless of the position of the jumper. This prevents the transmitter from
being accidentally left in simulate mode. Therefore, to enable the simulate
feature, the jumper must be inserted after power is applied to the transmitter.
CONSIDERATIONS
General The accuracy of a flow or pressure measurement depends on proper
installation of the transmitter and impulse piping. The piping between the
process and the transmitter must accurately transfer the pressure in order to
obtain accurate measurements. Mount the transmitter close to the process
and use minimum impulse piping to achieve best accuracy. Keep in mind the
need for easy access, safety of personnel, practical field calibration, and a
suitable transmitter environment. In general, install the transmitter to minimize
vibration, shock, and temperature fluctuations.
The following paragraphs discuss the factors necessary for a successful
transmitter installation.
