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.

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
[→]
.
3) Call "Review" and press

䊏Using the Transmitter Zero-adjustment
Screw
Before using the zero-adjustment screw outside the
transmitter case, confirm the following.
•Ext SW mode must be ENABLE. See Subsection
2.3.3 (17) for the setting procedure.
•Use a slotted screwdriver to turn the zero-adjustment
screw. Turn the screw clockwise to increase the
output or counterclockwise to decrease the output,
the zero point adjustment can be adjusted with a
resolution of 0.01% of the setting range.
The degree of zero adjustments varies with the
screw turning speed. Therefore, turn the screw
slowly for fine adjustment and quickly for coarse
adjustment.
CAUTION
Do not turn off the power to the transmitter
immediately after a zero adjustment. Powering
off within 30 seconds after a zero adjustment will
return the adjustment back to the previous
settings.
䊏Using the HART Communicator
Zero point can be adjusted by simple key operation of
the HART Communicator.
Select parameter Zero Trim, and press the OK (F4)
key twice. The zero point will be adjusted automati-
cally to the output signal 0% (4 mA DC). Confirm that
the setting value displayed for the parameter % rnge
is 0.0% before pressing the OK (F4) key. See Subsec-
tion for HART Communicator operating procedures.
1.1 Zero Point Adjustment
The DPharp supports several adjustment methods.
Select the method best suited for conditions matching
the state of the site.
Note that output signal can be checked by HART
Communicator.
Adjustment Method Description
Zero adjustment

Communicator
Set the present
input to 0%.
P.1-2 ‘Zero trim’
Zero adjustment
using the
external zero-
adjustment
screw
Adjust zero point using the zero-
adjustment screw on the transmitter.
This permits zero adjustment without
using the HART Communicator.
Accurately adjust the output current to
4mA DC or other target output value
using an ammeter that accurately reads
output currents.
Adjust for 0% output
at input level of 0%.
Adjust output to
the reference
value obtained
using other
means.
P.1-2 ‘Lower

If the input level
cannot easily be
made 0% (because of
tank level, etc.),
adjust output to the
reference value
obtained using other
means, such as a
glass gauge.

1.1.2 Using the Transmitter Zero-adjust-
ment Screw
Turn the zero-adjustment screw on the outside of the
transmitter case using a slotted screwdriver. Turn the
screw to the right to increase the zero point or to the
left to decrease the zero output; the zero adjusts in
increments of 0.01% of the range setting.
Note that the amount of adjustment to the zero point
changes according to the speed at which the screw is
turned. To make fine adjustments, turn the screw
slowly; to make coarse adjustments, turn the screw
quickly.
Note: When a zero point adjustment has been made do not turn of
the transmitter less than 30 seconds after adjustment.

1.2.2 Setting the Range Using the Range-
setting Switch
With actual pressure(s) being applied to the transmitter,
the range-setting switch (push-button) attached to the
integral indicator plate and the external zero-adjust-
ment screw allow users to change the lower- and
upper-range values for the measurement range (LRV
and URV) without the use of a HART Communicator.
However, a change in the display settings (scale range
and engineering unit) for the integral indicator requires
a HART Communicator.
Follow the procedure below to change the LRV and
URV settings.
Example: Rerange LRV to 0 and HRV to 20 kPa.
1) Connect the transmitter and allow them to warm up
for at least five minutes.
2) Press the range-setting push-button.
The integral indicator then displays LSET.
3) Apply a pressure of 0 kPa (atmospheric pressure) to
the high-pressure side of the transmitter. (Note 1)
4) Turn the external zero-adjustment screw (either in
the output-increase or -decrease direction).
The integral indicator displays the output signal (in
%). (Note 2)
5) Adjust the output signal to 0% (1 V DC) by
rotating the external zero-adjustment screw. Doing
so completes the LRV setting.
6) Press the range-setting pushbutton.
The integral indicator then displays USET.
7) Apply a pressure of 20 kPa to the high-pressure
side of the transmitter. (Note 1)
8) Turn the external zero-adjustment screw (either in
the output-increase or -decrease direction).
The integral indicator displays the output signal (in
%). (Note 2)
9) Adjust the output signal to 100% (5 V DC) by
rotating the external zero-adjustment screw. Doing
so completes the URV setting.
10)Press the range-setting pushbutton.
The transmitter then switches back to the normal
operation mode while maintaining the measurement
range at 0 to 20 kPa.
Note 1: Wait until the pressure inside the pressure-detector section
has stabilized before proceeding to the next step.
Note 2: If the pressure applied to the transmitter exceeds the
previous LRV (or URV) , the integral indicator may display
error number “Er.07” (In this case, the output signal percent
and “Er.07” are displayed alternately every two seconds).
Although “Er.07” is displayed, there is no need to worry and
you may proceed to the next step. However, should any
other error number be displayed, take the appropriate
measure in reference to Section 2.4 Self-Diagnostics,
“Errors Messages.”

1. ZERO POINT ADJUSTMENT
IMPORTANT
1. Do not turn off the power to the transmitter
immediately after completion of the change in
the LRV (and/or URV) setting(s). Note that
powering off within thirty seconds after setting
will ca use a return to the previous settings.
2. Changing LRV automatically changes URV to
the following value.
URV  previous URV  (new LRV  previous LRV)
3. If the range-setting push-button and external
zero-adjustment screw are not touched during
a range-change operation, the transmitter
automatically switches back to the normal
operation mode.

2.1 Conditions of Communica-
tion Line
2.1.1 Interconnection Between DPharp
and HART Communicator
The HART Communicator can interface with the
transmitter from the control room, the transmitter site,
or any other wiring termination point in the loop,
provided there is a minimum of 250 Ωbetween the
connection and the power supply. To communicate, it
must be connected in parallel with the transmitter; the
connections are non-polarized. Figure 2.1.1 illustrates
the wiring connections for direct interface at the
transmitter site for the DPharp. The HART Communi-
cator can be used for remote access from any terminal
strip as well.
