3.2.7 Impulse Line Connection Orientation
Setup
This function reverses the impulse line orientation.
Follow the procedure below to assign the high
pressure impulse line connection to the L side of the
transmitter.

3.2.8 Static Pressure Setup
The differential pressure transmitter can display the
static pressure also.
(1) Setting of the unit for static pressure
Follow the procedure below to change the static
pressure unit.
• Procedure to call up the display
DD and DTM
(excluding EJX_
HART 5[1.2])
[Root Menu]
→ Basic setup →
SP setup →
EJX_HART 5[1.2]
DTM
Configuration → Process Input (or
Static Pressure Sensor) →
→ SP Unit
Select the unit for static pressure
(Refer to subsection 3.2.2 Unit)
(2) Setting of the measuring range for static
pressure
Follow the procedure below to change the lower
range value (LRV) and upper range value (URV).
• Procedure to call up the display
DD and DTM
(excluding EJX_
HART 5[1.2])
[Root Menu]
→ Basic setup →
SP setup → SP Range → Keypad
input →
EJX_HART 5[1.2]
DTM
Configuration → Static Pressure
Sensor →
→ SP LRV
Set the lower range value (0 %) of
static pressure
→ SP URV
Set the upper range value (100 %)
of static pressure
(3) Selection of Gauge pressure and Absolute
pressure
Either the gauge pressure or absolute pressure can
be selected to display on the LCD display.
Absolute pressure is selected when the transmitter
is shipped.
• Procedure to call up the display
DD and DTM
(excluding EJX_
HART 5[1.2])
[Root Menu]

is shipped
(4) Selection of pressure side
Either the high or low pressure side of capsule can
be selected to monitor the static pressure.
High pressure side is selected when the transmitter
is shipped.
• Procedure to call up the display
