PRELIMINARY
This manual describes the function, performance, and
operating procedures of the DPharp EJA Series with
HART protocol. The DPharp EJA Series with HART
protocol uses the same pressure sensing element as in
DPharp EJA with BRAIN protocol. Therefore, this
manual describes only the functions unique to HART
Communicator operating procedures which are not
covered in the DPharp EJA with BRAIN protocol
instruction manual. For the items listed below which
are common to both the HART protocol and BRAIN
protocol, see the applicable user’s manuals listed in
Table 1.

CAUTION
Matching of communicator DD and instrument DD
Before using model 275 HART communicator,
check that the DD(Device Description) installed in
the communicator matches to that of instruments
to set up. To check the DD in the instrument or
the HART communicator, follow the steps below.
If the correct DD is not installed in the communi-
cator, you must upgrade the DD at the HART
official programming sites. For communication
tools other than Model 275 HART communicator,
contact vendors of each for upgrade information.
1. Checking the DD in the instrument
1) Connect the communicator to the instrument
to set up.
2) Call "Device setup" and press
