IM 01C21B01-01E
2. HANDLING CAUTIONS
2.4 Selecting the Installation
Location
CAUTION
Maximum working pressure of the model
EJA120A differential pressure transmitter is 50
kPa {0.5 kgf/cm2}.
Should the pressure exceed 50 kPa {0.5 kgf/
cm2}, it is possible to break the sensor. Proceed
with caution when applying pressure.
The transmitter is designed to withstand severe
environmental conditions. However, to ensure stable
and accurate operation for years, observe the following
precautions when selecting an installation location.
(a) Ambient Temperature
Avoid locations subject to wide temperature
variations or a significant temperature gradient. If
the location is exposed to radiant heat from plant
equipments, provide adequate thermal insulation
and/or ventilation.
(b) Ambient Atmosphere
Avoid installing the transmitter in a corrosive
atmosphere. If the transmitter must be installed in a
corrosive atmosphere, there must be adequate
ventilation as well as measures to prevent intrusion
or stagnation of rain water in conduits.
(c) Shock and Vibration
Select an installation site suffering minimum shock
and vibration (although the transmitter is designed
to be relatively resistant to shock and vibration).
2.6 Waterproofing of Cable
Conduit Connections
Apply a non-hardening sealant to the threads to
waterproof the transmitter cable conduit connections.
(See Figure 6.4.2a, 6.4.2b and 6.4.2c.)
2.7 Restrictions on Use of Radio
Transceiver
IMPORTANT
Although the transmitter has been designed to
resist high frequency electrical noise, if a radio
transceiver is used near the transmitter or its
external wiring, the transmitter may be affected
by high frequency noise pickup. To test for such
effects, bring the transceiver in use slowly from a
distance of several meters from the transmitter,
and observe the measurement loop for noise
effects. Thereafter, always use the transceiver
outside the area affected by noise.
(d) Installation of Explosion-protected Transmitters
Explosion-protected transmitters can be installed in
hazardous areas according to the types of gases for
which they are certified. See Subsection 2.9
“Installation of Explosion Protected Type Transmitters.”
2.5 Pressure Connection
WARNING
• Instrument installed in the process is under
pressure. Never loosen the process connector
bolts to avoid the dangerous spouting of
process fluid.
• During draining condensate from the pressuredetector section, take appropriate care to avoid
contact with the skin, eyes or body, or inhalation of vapors, if the accumulated process fluid
may be toxic or otherwise harmful.
The following precautions must be observed in order to
safely operate the transmitter under pressure.
(a) Make sure that the four process connector bolts are
tightened firmly.
(b) Make sure that there are no leaks in the impulse
piping.
(c) Never apply a pressure higher than the specified
maximum working pressure.
2.8 Insulation Resistance and
Dielectric Strength Test
Since the transmitter has undergone insulation resistance and dielectric strength tests at the factory before
shipment, normally these tests are not required.
However, if required, observe the following precautions in the test procedures.
(a) Do not perform such tests more frequently than is
absolutely necessary. Even test voltages that do not
cause visible damage to the insulation may degrade
the insulation and reduce safety margins.
(b) Never apply a voltage exceeding 500 V DC (100 V
DC with an internal lightning protector) for the
insulation resistance test, nor a voltage exceeding
500 V AC (100 V AC with an internal lightning
protector) for the dielectric strength test.
2-2
IM 01C21B01-01E
2. HANDLING CAUTIONS
(c) Before conducting these tests, disconnect all signal
lines from the transmitter terminals. Perform the
tests in the following procedure:
and may cause dangerous condition. Please contact
Yokogawa for any repair or modification required to
the instrument.
• Insulation Resistance Test
1) Short-circuit the + and – SUPPLY terminals in the
terminal box.
2) Turn OFF the insulation tester. Then connect the
insulation tester plus (+) lead wire to the shorted
SUPPLY terminals and the minus (–) leadwire to
the grounding terminal.
3) Turn ON the insulation tester power and measure
the insulation resistance. The voltage should be
applied short as possible to verify that the insulation resistance is at least 20 M1.
4) After completing the test and being very careful not
to touch exposed conductors disconnect the
insulation tester and connect a 100 k1 resistor
between the grounding terminal and the shortcircuiting SUPPLY terminals. Leave this resistor
connected at least one second to discharge any
static potential. Do not touch the terminals while it
is discharging.
• Dielectric Strength Test
1) Short-circuit the + and – SUPPLY terminals in the
terminal box.
2) Turn OFF the dielectric strength tester. Then
connect the tester between the shorted SUPPLY
terminals and the grounding terminal. Be sure to
connect the grounding lead of the dielectric strength
tester to the ground terminal.
3) Set the current limit on the dielectric strength tester
to 10 mA, then turn ON the power and gradually
increase the test voltage from ‘0’ to the specified
voltage.
4) When the specified voltage is reached, hold it for
one minute.
5) After completing this test, slowly decrease the
voltage to avoid any voltage surges.
2.9 Installation of Explosion
Protected Type

dimension can be changed 51 mm or 57 mm.
The transmitter is shipped with the process connection, according to the ordering specifications. To
change the orientation of the process connections,
refer to Section 4.3.
The transmitter can be mounted on a nominal 50
mm (2-inch) pipe using the mounting bracket
supplied, as shown in Figure 4.2.2 and 4.2.3. The
transmitter can be mounted on either a horizontal or
a vertical pipe.
When mounting the bracket on the transmitter,

4.4 Swapping the High/Lowpressure Side Connection
4.4.2 Using the BRAIN TERMINAL BT200
This method is applicable only to the Model EJA110AL, EJA110A-M, EJA110A-H, EJA120A-E,
EJA130A-M and EJA130A-H.
4.4.1 Rotating Pressure-detector Section
180°
With a BRAIN TERMINAL, you can change which
process connection is used as the high-pressure side
without mechanically rotating the pressure-detector
section 180 as described in Subsection 4.4.1. To
change, call parameter ‘D45: H/L SWAP’ and select
REVERSE (right side: low pressure; left side: high
pressure) or select NORMAL to change back to normal
(right side: high pressure; left side: low pressure).
This procedure can be applied only to a transmitter
with a vertical impulse piping type.
The procedure below can be used to turn the pressuredetector assembly 180°. Perform this operation in a
maintenance shop with the necessary tools laid out and
ready for use, and then install the transmitter in the
field after making the change.
1) Use a Allen wrench (JIS B4648, nominal 5 mm) to
remove the two Allen screws at the joint between
the pressure-detector section and transmitter section.
2) Leaving the transmitter section in position, rotate
the pressure-detector section 180°.
3) Tighten the two Allen screws to fix the pressuredetector section and transmitter section together (at
a torque of 5 N·m).

5. INSTALLING IMPULSE PIPING
5.
INSTALLING IMPULSE PIPING
5.1 Impulse Piping Installation
Precautions
(4) Connecting the Transmitter and 3-Valve
Manifold
A 3-valve manifold consists of two stop valves to
block process pressure and an equalizing valve to
equalize the pressures on the high and low pressure
sides of the transmitter. Such a manifold makes it
easier to disconnect the transmitter from the impulse
piping, and is convenient when adjusting the transmitter zero point.
The impulse piping that connects the process outputs to
the transmitter must convey the process pressure
accurately. If, for example, gas collects in a liquidfilled impulse piping, or the drain of a gas-filled
impulse piping becomes plugged, the impulse piping
will not convey the pressure accurately. Since this will
cause errors in the measurement output, select the
proper piping method for the process fluid (gas, liquid,
or steam). Pay careful attention to the following points
when routing the impulse piping and connecting the
impulse piping to the transmitter.
There are two types of 3-valve manifold: the pipemounting type and the direct-mounting type; care
should be taken with respect to the following points
when connecting the manifold to the transmitter.
Pipe-Mounting Type 3-Valve Manifold
(Figure 5.1.1b)
1) Screw nipples into the connection ports on the
transmitter side of the 3-valve manifold, and into the
impulse piping connecting ports on the process
connectors. (To maintain proper sealing, wind
sealing tape around the nipple threads.)
2) Mount the 3-valve manifold on the 50 mm (2-inch)
pipe by fastening a U-bolt to its mounting bracket.
Tighten the U-bolt nuts only lightly at this time.
3) Install the pipe assemblies between the 3-valve
manifold and the process connectors and lightly
tighten the ball head lock nuts. (The ball-shaped
ends of the pipes must be handled carefully, since
they will not seal properly if the ball surface is
scratched or otherwise damaged.)
4) Now tighten the nuts and bolts securely in the
following sequence:
Process connector bolts A transmitter-end ball head
lock nuts A 3-valve manifold ball head lock nuts A
3-valve manifold mounting bracket U-bolt nuts
5.1.1 Connecting Impulse Piping to the
Transmitter
(1) Check the High and Low Pressure Connections on the Transmitter (Figure 5.1.1a)
Symbols “H” and “L” are shown on a capsule assembly to indicate high and low pressure side. Connect the
impulse piping to the “H” side, and the low impulse
piping to the “L” side.

(2) Changing the Process Connector Piping
Connections (Figure 4.1)
The impulse piping connection distances can be
changed between 51 mm, 54 mm and 57 mm by
changing the orientation of the process connectors.
This is convenient for aligning the impulse piping with
the process connectors when connecting the piping.
(3) Tightening the Process Connector Mounting Bolts
After connecting the impulse piping, tighten the
process connector mounting bolts uniformly.

impulse piping will be connected).
5.1.2 Routing the Impulse Piping
(1) Process Pressure Tap Angles
If condensate, gas, sediment or other extraneous
material in the process piping gets into the impulse
piping, pressure measurement errors may result. To
prevent such problems, the process pressure taps must
be angled as shown in Figure 5.1.2 according to the
kind of fluid being measured.

(6) Preventing Wind Speed Effects in Very
Low Differential Pressure Measurement
(2) Position of Process Pressure Taps and
Transmitter
If condensate (or gas) accumulates in the impulse
piping, it should be removed periodically by opening
the drain (or vent) plugs. However, this will generate a
transient disturbance in the pressure measurement, and
therefore it is necessary to position the taps and route
the impulse piping so that any extraneous liquid or gas
generated in the leadlines returns naturally to the
process piping.
IMPORTANT
When using a differential pressure transmitter to
measure very low pressures (draft pressure),
the low pressure connection port is left open to
atmospheric pressure (the reference pressure).
Any wind around the differential pressure
transmitter will therefore cause errors in the
measurement. To prevent this, it will be necessary either to enclose the transmitter in a box,
or to connect a impulse piping to the low
pressure side and insert its end into a windexcluding pot (cylindrical with a base plate).
• If the process fluid is a gas, then as a rule the
transmitter must be located higher than the process
pressure taps.
• If the process fluid is a liquid or steam, then as a
rule the transmitter must be located lower than the
process pressure taps.
(3) Impulse Piping Slope
The impulse piping must be routed with only an
upward or downward slope. Even for horizontal
routing, the impulse piping should have a slope of at
least 1/10 to prevent condensate (or gases) from
accumulating in the pipes.
(7) Preventing Freezing
If there is any risk that the process fluid in the impulse
piping or transmitter could freeze, use a steam jacket or
heater to maintain the temperature of the fluid.
(4) Temperature Difference Between Impulse
Piping
If there is a temperature difference between the high
and low impulse piping, the density difference of the
fluids in the two lines will cause an error in the
measurement pressure. When measuring flow, impulse
piping must be routed together so that there is no
temperature difference between them.
NOTE
After completing the connections, close the valves
on the process pressure taps (main valves), the
valves at the transmitter (stop valves), and the
impulse piping drain valves, so that condensate,
sediment, dust and other extraneous material
cannot enter the impulse piping.
(5) Condensate Pots for Steam Flow Measurement
If the liquid in the impulse piping repeatedly condenses
or vaporizes as a result of changes in the ambient or
process temperature, this will cause a difference in the
fluid head between the high pressure and low pressure
sides. To prevent measurement errors due to these head
differences, condensate pots are used when measuring
steam flow.

5.2 Impulse Piping Connection
Examples
Figure 5.2 shows examples of typical impulse piping
connections. Before connecting the transmitter to the
process, study the transmitter installation location, the
process piping layout, and the characteristics of the
process fluid (corrosiveness, toxicity, flammability,
etc.), in order to make appropriate changes and
additions to the connection configurations.
Note the following points when referring to these
piping examples.
• The high pressure connecting port on the transmitter is shown on the right (as viewed from the front).
• The transmitter impulse piping connection is shown
for a vertical impulse piping connection configuration in which the direction of connection is either
upwards or downwards.
• If the impulse piping is long, bracing or supports
should be provided to prevent vibration.
• The impulse piping material used must be compatible with the process pressure, temperature, and
other conditions.
• A variety of process pressure tap valves (main
valves) are available according to the type of
connection (flanged, screwed, welded), construction
(globe, gate, or ball valve), temperature and
pressure. Select the type of valve most appropriate
for the application.

6.1 Wiring Precautions
IMPORTANT
• Lay wiring as far as possible from electrical
noise sources such as large capacity transformers, motors, and power supplies.
• Remove electrical connection dust cap before
wiring.
• All threaded parts must be treated with waterproofing sealant. (A non-hardening silicone
group sealant is recommended.)
• To prevent noise pickup, do not pass signal
and 0ówer cables through the same ducts.
• Explosion-protected instruments must be wired
in accordance with specific requirements (and,
in certain countries, legal regulations) in order
to preserve the effectiveness of their explosionprotected features.
• The terminal box cover is locked by an Allen
head bolt (a shrouding bolt) on CENELEC and
IECEx flameproof type transmitters. When the
shrouding bolt is driven clockwise by an Allen
wrench, it is going in and cover lock is released, and then the cover can be opened by
hand. See Subsection 9.4 “Disassembly and

If the transmitter is equipped with an integral
indicator, its indication can be used to confirm that
the transmitter is operating properly.
7.1 Preparation for Starting
Operation
The Model EJA110A, EJA120A and EJA130A
pressure transmitter measures the flow rates and the
pressure of liquids, gases, and steam, and also liquid
levels. This section describes the operation procedure
for the EJA110A as shown in Figure 7.1 (vertical
impulse piping type, high-pressure connection: right
side) when measuring a liquid flow rate.
Orifice
NOTE
Check that the process pressure tap valves,
drain valves, and 3-valve manifold stop valves
on both low pressure and high pressure sides
are closed, and that the 3-valve manifold equalizing valve is opened.
Tap valve
(high pressure)
Tap valve
(low pressure)
(a) Follow the procedures below to introduce process
pressure into the impulse piping and transmitter.
1) Open the low pressure and high pressure tap valves
to fill the impulse piping with process liquid.
2) Slowly open the high pressure stop valve to fill the
transmitter pressure-detector section with process
liquid.
3) Close the high pressure stop valve.
4) Gradually open the low pressure stop valve and
completely fill the transmitter pressure-detector
section with process liquid.
5) Close the low pressure stop valve.
6) Gradually open the high pressure stop valve. At this
time, equal pressure is applied to the low and high
pressure sides of the transmitter.
7) Check that there are no liquid leaks in the impulse
piping, 3-valve manifold, transmitter, or other
components.
Venting Gas from the Transmitter Pressuredetector Section
• Since the piping in the example of Figure 7.1 is
constructed to be self-venting, no venting operation is
required. If it is not possible to make the piping selfventing, refer to Subsection 7.5 for instructions.
Leave the equalizing valve open even after venting
gas.

Using the Transmitter Zero-adjustment
Screw
Before adjusting a screw, check that the parameter
J20: EXT ZERO ADJ displays ENABLE. See
Subsection 8.3.3 (15) for the setting procedure.
• Measuring range ....... See Subsection 8.3.3 (2)
• Output/integral indicator mode .........
See Subsection 8.3.3 (4)
• Operation mode ......... See Subsection 8.3.3 (9)
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 made with a resolution of
0.01% of the setting range. Since the degree of zero
adjustments varies with the screw turning speed, turn
the screw slowly for fine adjustment and quickly for
coarse adjustment.

7. OPERATION
Using the BT200
Zero point can be adjusted by simple key operation of
the BT200.
IMPORTANT
• Remove the BT200 from the terminal box, and
confirm that none of the terminal screws are
loosened.
• Close the terminal box cover and the amplifier
cover. Screw each cover in tightly until it will
not turn further.
• Two covers are required to be locked on the
CENELEC and IECEx Flameproof type transmitters. An Allen head bolts (shrouding bolts)
are provided under edge of the each cover for
locking. When a shrouding bolts are driven
counterclockwise by an Allen wrench, it is
coming out and locks up a cover. (See page 93) After locking, the covers should be confirmed not to be opened by hand.
• Tighten the zero-adjustment cover mounting
screw to fix the cover in position.
Select parameter J10: ZERO ADJ, and press the
ENTER key twice. The zero point will be adjusted
automatically to the output signal 0% (4 mA DC).
Confirm that the setting value displayed for the
parameter is ‘0.0%’ before pressing the ENTER key.
See Subsection 8.3.3 (15) for BT200 operating procedures.

7.3 Starting Operation
7.4 Shutting Down Operation
After completing the zero point adjustment, follow the
procedure below to start operation.
Shut down the transmitter operation as follows.
1) Turn off the power.
2) Close the low pressure stop valve.
3) Open the equalizing valve.
4) Close the high pressure stop valve.
5) Close the high pressure and low pressure tap
valves.
1) Close the equalizing valve.
2) Gradually open the low pressure stop valve.
This places the transmitter in an operational condition.
3) Confirm the operating status. If the output signal
exhibits wide fluctuations (hunting) due to periodic
variation in the process pressure, use BT200 to
dampen the transmitter output signal. Confirm the
hunting using a receiving instrument or the integral
indicator, and set the optimum damping time
constant. See Subsection 8.3.3 (3), “Damping Time
Constant Setup.”
4) After confirming the operating status, perform the
following.
NOTE
• Whenever shutting down the transmitter for a
long period, remove any process fluid from the
transmitter pressure-detector section.
• The equalizing valve must be left OPEN.

7. OPERATION
7.5.2 Venting Gas
7.5 Venting or Draining Transmitter Pressure-detector Section
1) Gradually open the vent screw to vent gas from the
transmitter pressur-detector section. (See Figure
7.5.2.)
2) When the transmitter is completely vented, close
the vent screw.
3) Tighen the vent screw to a torque of 10 N·m.
Since this transmitter is designed to be self-draining
and self-venting with vertical impulse piping connections, neither draining nor venting will be required if
the impulse piping is configured appropriately for selfdraining or self-venting operation.
If condensate (or gas) collects in the transmitter
pressure-detector section, the measured pressure may
be in error. If it is not possible to configure the piping
for self-draining (or self-venting) operation, you will
need to loosen the drain (vent) screw on the transmitter
to completely drain (vent) any stagnated liquid (gas).
Vent screw
However, since draining condensate or bleeding off gas
gives the pressure measurement disturbance, this
should not be done when the loop is in operation.
Vent screw
When you loosen the vent screw, the gas
escpes in the direction of the arrow.
F0707.EPS
WARNING
Figure 7.5.2 Venting the Transmitter
Since the accumulated liquid (or gas) may be
toxic or otherwise harmful, take appropriate care
to avoid contact with the body, or inhalation of
vapors.
7.6 Setting the Range Using the
Range-setting Switch
With actual pressure being applied to the transmitter,
the range-setting switch (push-button) located on the
optional integral indicator plate and the external zeroadjustment screw allow users to change (re-range) the
low- and high-limit values for the measurement range
(LRV and HRV) without using BT200. However, other
changes in the display settings (scale range and
engineering unit) for the integral indicator requires
BT200.
7.5.1 Draining Condensate
1) Gradually open the drain screw or drain plug and
drain the transmitter pressure-detector section. (See
Figure 7.5.1.)
2) When all accumulated liquid is completely removed, close the drain screw or drain plug.
3) Tighten the drain screw to a torque of 10 N·m, and
the drain plug to a torque of 34 to 39 N·m.
Follow the procedure below to change the LRV and
HRV settings.
[Example]
Rerange LRV to 0 and HRV to 3 MPa.
1) Connect the transmitter and apparatus as shown in
Figure 9.3.1 and 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 transmitter. (Note 1)
4) Turn the external zero-adjustment screw in the
desired 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.

Drain screw
When you loosen the drain screw or drain
plug, the accumulated liquid will be expelled
in the direction of the arrow.

7. OPERATION
6) Press the range-setting push-button. The integral
indicator then displays “HSET.”
7) Apply a pressure of 3 MPa to the transmitter. (Note 1)
8) Turn the external zero-adjustment screw in the
desired 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 HRV setting.
10) Press the range-setting push-button. The transmitter
then switches back to the normal operation mode
with the measurement range of 0 to 3 MPa.
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 HRV), 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, you may proceed to the next
step. However, should any other error number be displayed,
take the appropriate measure in reference to Subsection
8.5.2, “Errors and Countermeasures.”
IMPORTANT
• Do not turn off the power to the transmitter
immediately after completion of the change in
the LRV and/or HRV setting(s). Note that
powering off within thirty seconds after setting
will cause a return to the previous settings.
• Changing LRV automatically changes HRV to
the following value.
HRV = previous HRV + (new LRV – previous LRV)
• 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.

8.3.2 Parameter Usage and Selection
IMPORTANT
Before describing the procedure for setting parameters,
we present the following table showing how the
parameters are used and in what case.
If the transmitter is turned off within 30 seconds
after parameters have been set, the set data will
not be stored and the terminal returns to previous settings.
Table 8.3.1 Parameter Usage and Selection
Setup Item
Tag No. setup
P.8-7
Calibration range setup
P.8-7
Description
Sets the Tag No. (using 16 alphanumeric characters).
Damping time constant setup
P.8-8
Output and integral indicator display
mode setup P.8-9
Adjusts the output response speed for 4 to 20 mA DC at amplifier.
Can be set from 0.50 to 100.00 s. (from 0.00 to 100.00 s with quick response mode on)
Sets modes for output signal and integral indicator to “Linear mode”
(proportional to input differential pressure) or to “Square root mode” (proportional to flow).
Output signal low cut mode setup
P.8-9
Used mainly to stabilize output near 0% if output signal is the square root mode.
Two modes are available: forcing output to 0% for input below a specific value, or changing
to proportional output for input below a specific value.
Integral indicator display function
P.8-10
Available from the following 5 types of integral indicator scale ranges and units:
input pressure, % of range, user set scale, input static pressure, % of static pressure
range, and alternating among any four of the above.
When using the user set scale, 4 types of data should be configurated in advance:
user set scale setting, unit (BT200 only), display value at 4 mA DC (LRV), and display
value at 20 mA DC (URV).
Note: LRV and URV can be specified with range value specifications up to 5
digits (excluding any decimal point) within the range of –32000 to 32000.
Unit setup for displayed temperature
P.8-11
Sets a unit for temperatures displayed on the BT200.
Unit setup for displayed static
pressure P.8-11
Sets a unit for static pressure displayed on the BT200.
Operation mode (normal/reverse
signal) setup
P.8-12
Reverses the direction for 4 to 20 mA DC output relative to input.
Reverse mode is used for applications in which safety requires that output be
driven toward 20 mA if input is lost.
Impulse line connection orientation
(higher pressure on right/left side)
setup P.8-12

MAINTENANCE
9.1 Overview
WARNING
Since the accumulated process fluid may be
toxic or otherwise harmful, take appropriate care
to avoid contact with the body, or inhalation of
vapors during draining condensate or venting
gas in transmitter pressure-detector section and
even after dismounting the instrument from the
process line for maintenance.
Maintenance of the transmitter is easy due to its
modular construction. This chapter describes the
procedures for calibration, adjustment, and the disassembly and reassembly procedures required for
component replacement.
9.2 Calibration Instruments Selection
Table 9.2.1 shows the instruments required for calibration. Select instruments that will enable the transmitter
to be calibrated or adjusted to the required accuracy.
The calibration instruments should be handled carefully
so as to maintain the specified accuracy.
9.3 Calibration
Use the procedure below to check instrument operation
and accuracy during periodic maintenance or troubleshooting.
1) Connect the instruments as shown in Figure 9.3.1
and warm up the instruments for at least five
minutes.
Since the transmitters are precision instruments,
carefully and thoroughly read the following sections
for proper handling during maintenance.
IMPORTANT
• To adjust the transmitter for highest accuracy,
make adjustments with the power supply
voltage and load resistance including leadwire
resistances set close to the conditions under
which the transmitter is installed.
• If the measurement range 0% point is 0 kPa or
shifted in the positive direction (suppressed
zero), the reference pressure should be applied
as shown in the figure.
If the measurement range 0% point is shifted in
the negative direction (elevated zero), the
reference pressure should be applied using a
vacuum pump.
IMPORTANT
• As a rule, maintenance of this transmitter
should be implemented in a maintenance
service shop where the necessary tools are
provided.
• The CPU assembly contains sensitive parts
that may be damaged by static electricity.
Exercise care so as not to directly touch the
electronic parts or circuit patterns on the board,
for example, by preventing static electrification
by using grounded wrist straps when handling
the assembly. Also take precautions such as
placing a removed CPU assembly into a bag
with an antistatic coating.
2) Apply reference pressures of 0%, 50%, and 100% of
the measurement range to the transmitter. Calculate
the errors (differences between digital voltmeter
readings and reference pressures) as the pressure is
increased from 0% to 100% and is decreased from
100% to 0%, and confirm that the errors are within
the required accuracy.

procedures involving traceability of each instrument to higher-level standards are required for calibration to the 0.1% level, there are
difficulties in calibration to this level in the field. For calibration to the 0.1% level, contact Yokogawa representatives from which the

Cautions for Flameproof Type Transmitters
Users are prohibited by law from modifying the
construction of a flameproof type transmitter.
This would invalidate the agency approval and
the transmitter’s use in such rated area.
Thus the user is prohibited from using a flameproof type transmitter with its integral indicator
removed, or from adding an integral indicator to
a transmitter. If such modification is absolutely
required, contact Yokogawa.
Always turn OFF power and shut off and release
pressures before disassembly. Use proper tools for all

CAUTION
Precautions for CENELEC and IECEx Flameproof Type Transmitters
• Flameproof type transmitters must be, as a
rule, removed to a non-hazardous area for
maintenance and be disassembled and reassembled to the original state.
• On the flameproof type transmitters the two
covers are locked, each by an Allen head bolt
(shrouding bolt). When a shrouding bolt is
driven clockwise by an Allen wrench, it is going
in and cover lock is released, and then the
cover can be opened.
When a cover is closed it should be locked by a
shrouding bolt without fail. Tighten the shrouding bolt to a torque of 0.7 N·m.
This subsection describes the procedure for replacing
an integral indicator. (See Figure 9.4.2)
Removing the Integral Indicator
1) Remove the cover.
2) Supporting the integral indicator by hand, loosen its
two mounting screws.
3) Dismount the LCD board assembly from the CPU
assembly.
When doing this, carefully pull the LCD board
assembly straight forward so as not to damage the
connector pins between it and the CPU assembly.

• Rinse thoroughly with clean water after cleaning.
5) Replace the cover.
9.4.3 Cleaning and Replacing the Capsule
Assembly
This subsection describes the procedures for cleaning
and replacing the capsule assembly. (See Figure 9.4.3.)
CAUTION
Cautions for Flameproof Type Transmitters
Users are prohibited by law from modifying the
construction of a flameproof type transmitter. If
you wish to replace the capsule assembly with
one of a different measurement range, contact
Yokogawa.
The user is permitted, however, to replace a
capsule assembly with another of the same
measurement range. When doing so, be sure to
observe the following.
• The replacement capsule assembly must have
the same part number as the one being replaced.
• The section connecting the transmitter and
capsule assembly is a critical element in
preservation of flameproof performance, and
must be checked to verify that it is free of
dents, scratches, and other defects.
• After completing maintenance, be sure to
securely tighten the Allen screws that fasten
the transmitter section and pressure-detector
section together.
1) Remove the CPU assembly as shown in Subsection
9.4.2.
2) Remove the two Allen screws that connect the
transmitter section and pressure-detector section.
3) Separate the transmitter section and pressuredetector section.
4) Remove the nuts from the four flange bolts.
5) Hold the capsule assembly by hand and remove the
