Safety Precautions
This product is designed to be used by a person with specialized
knowledge.
The general safety precautions described herein must be observed
during all phases of operation. If the instrument is used in
a manner not specied in this manual, the protection provided by
the instrument may be impaired.
This manual is an essential part of the product; keep it a safe place
for future reference.
YOKOGAWA assumes no liability for the customer’s failure to
comply with these requirements.
The following symbols are used on this instrument and
in this manual.
Handle with Care.
Refer to the user’s manual or service manual.
This symbol appears on dangerous locations on
the instrument which require special instructions for
proper handling or use.
Calls attention to actions or conditions that could cause serious
or fatal injury to the user, and precautions that can be taken to
prevent such occurrences.
Check the Operating Environment
• This product is a pump for the pressure calibrator.
Do not use for any other purpose.
• Do not use the product if there is a problem with its physical
appearance.
• This product is manufactured in accordance with Sound
Engineering Practice (SEP).
• Be sure to check the measurement environment and conditions.
If you are using the product in an environment in which
supervision by a certied person is required by law or other
ordinance, be sure to perform measurements in accordance
with appropriate safety management standards.
• Use tubing (connector, hose, etc.) that can withstand the
pressure to be generated.
• Make sure that air does not leak from the tubing
(connector, hose, etc.) connections.
If a connection comes loose or if air leaks under high pressure,
it can endanger the user or the surrounding instruments.
• Do not apply pressure exceeding the maximum allowable
pressure of the device under test (DUT).
Do not generate pressure exceeding the maximum working
pressure (M.W.P).
• Removing tubing when there is remaining pressure is extremely
dangerous.
Safely release the pressure before removing tubing
(connector, hose, etc.) from the pressure pump.
• This instrument is not explosion-proof.
Do not use the instrument in the presence of ammable gases
or vapors. Doing so is extremely dangerous.

operation of the instrument.
Be Sure to Read the Pressure Meter User’s Manual
If you are going to use this product in combination with
a pressure meter (standard pressure meter/monitor),
be sure to read the pressure meter user’s manual,
and use the instruments correctly.
Do use the product in:
• In direct sunlight or near heat sources
• In an environment that is subject to large levels of mechanical
vibration
• Near noise sources, such as high-voltage equipment or
power source
• Near strong magnetic eld sources
• In an environment with excessive amounts of soot, grease,
dust, or corrosive gas
• In an environment where ignition or explosion may occur,
such as where ammable gas is present
Note
After use, store the pressure pump in the hand pump case or
in a safe place.
Note
If you require high airtightness or high withstand pressure,
use a connector with a ferrule or sleeve, not the supplied
the high-pressure hose or quick adapter.
Use a hose that can withstand the pressure that you will generate.

3.1 Handling Precautions
Be sure to check the operating environment (safety).
Before use, be sure to check that connectors are secure,
that there are no intrusion of foreign substances,
and that there are no damages.
In addition, use the same thread specications for all connectors.
Perform preliminary pressure tests on tubing and other parts of
the system.
If you are applying pressure using a hand pump,
be sure to monitor the pressure with a standard pressure meter
(monitor).
3.2 Connecting Connectors
• Use connectors appropriate for the thread specications of
the device under test (DUT) and tubing.
Otherwise, leakage and damage to threads may result.
• Apply appropriate seal tape to the connecting surface of
the connector.

1/4” NPT

■ UsingTwoWrenches
To prevent leakage, you must tighten the connector or
quick adapter rmly.
Using a wrench only on the connector side may break
the pressure pump.
Use two wrenches to prevent force from being applied to
the pressure pump.
(The same applies when you connect a connector to
the standard pressure meter.)
3.3 Generating Pressure
• Remove tubing and wiring from the calibration target before
carrying out the procedure.
• Only connect to this pressure pump.
Do not connect to another high pressure source.
• Be sure to observe all safety precautions to avoid injury and
damage to the device under test (DUT).

MAXIMUM FILL LEVEL
• For the liquid (pressure medium), use distilled water or clean oil
(up to hydraulic oil 100 (30W)).
Select a media type that is suitable for the device under test
(DUT) and the pressure pump.
• The reservoir seal is made of uorocarbon and nonmetallic
plastic. Do not use highly viscous oil (higher than 30W).
• Hydrocarbon uids should never be used in oxygen service
test device.
• High pressure gases is extremely dangerous.
“Prime” the test system to minimize air introduced into the DUT.
• Use connectors and hoses appropriate for the source pressure
value.
Note
We recommend that the user keep a record of the kind of media
being used (was used previously). (records of use, cleaning, etc.)
[ Procedure ]
(1) Connect the standard pressure meter.
Open the hose that will be connected to the DUT (for “priming”).
(2) Remove the cap from thellport.
Fill the media reservoir 1/2 (50%) to 2/3 full, and close the cap.
• Be sure to ll the reservoir at least half way full to prevent
intrusion of air.
• Do not exceed the ll line (maximum ll level).
• Minimize load capacity.
(3) Adjust the vernier adjustment to the mid position.
(4) Close the needle bleed valve.
(5) While squeezing the handle, push the stroke meter into
prime mode.
Prime mode: Mode that allows the maximum amount of
handle movement
(6) Open the hose that will be connected to the DUT,
and squeeze the handle to beginning the priming process.
Priming: The act of squeezing the handle until media
lls the hose all the way to the end to prevent
the intrusion of air
(Using full stroke on the handle removes air in the pump and hose.)
(7) After checking that the media has lled the hose all the way
to the end, connect the hose to the DUT.
(8) Apply pressure (squeeze the handle) just enough so that
you can verify a sharp rise in pressure on the standard
pressure meter.
(You can feel the pressure changing through the handle that
you are squeezing.)
While squeezing the handle, push the stroke limiter
to switch to pump mode.
Pump mode: Mode in which the amount of
handle movement is limited
If you do not apply the stroke limiter at the appropriate timing,
you may not be able to generate pressure up to
the specications.
After applying sudden pressure, if you remove your hand from
the handle before applying the stroke limiter, it will be difcult
to operate the handle the next time.
If this happens, loosen the needle bleed valve to release some
of the pressure, close the needle bleed valve,
and apply pressure (operate the handle) again.
(9) Check that the needle valve is closed.
(10) Squeeze the handle to apply pressure near the target
pressure.
(11) Adjust the vernier adjustment to “ne tune” the pressure to
the targetvalue.
Note
Priming may require you to squeeze the handle numerous times
depending on the connected load capacity (media capacity).
If the volume is large, prime many times.
3.4 Releasing Pressure
To prevent accidents, safely return the pressure to zero
(release the pressure) before removing the connector and hose.
After generating pressure, carefully open the needle valve to
release the pressure. (The media will turn to the reservoir.)
Make sure that the media does not overow from the reservoir.
When you are nished, drain the media from the reservoir.
Note
After use, store the pressure pump in the hand pump case or
in a safe place.
We recommend that you clean the reservoir before storing it.
4. Cleaning
After use (calibration), clean the media reservoir.
Clean it in way that is appropriate for the liquid (pressure medium)
that you used.
5. Troubleshooting
If you cannot increase the pressure with the hand pump
(if the pressure decreases), check the following.
• Check that the media reservoir cap is closed.
• Check that the needle valve is closed.
• Check the thread specications of the connection port.
Check that the connection is secure (use seal tape or other
measures).
• Check that the stroke limiter is being used adequately.
If you cannot determine the cause, continuing with the procedure
is dangerous. Stop immediately.
If the product does not work properly, contact your nearest
YOKOGAWA dealer.
