Do not use this product under conditions that exceed the environmental conditions indicated in the
specifications. Doing so could result in a product failure or damage.
Do not wash the product in water. Doing so could cause an electric shock, fire, or failure.
To clean dirty surfaces, wipe with a soft dry cloth (moistened with a neutral detergent for stubborn dirt).
Remove the batteries and disconnect the AC adapter before cleaning or inspecting the product. Not doing so
could cause an electric shock, battery leakage, or other problems.

Caution Labels
Caution labels are affixed to the side of this product. During use, be sure to comply with the cautions noted.
AVOID SHOCK
Do not drop the product or otherwise
expose it to strong impacts. Doing so
could cause a product failure or
accident.
KEEP DRY
Do not touch the power cord, plug, or outlet
with wet hands. Also, do not wet the product
when cleaning it. Doing so could cause an
electric shock, fire, or product failure.
■
Measured Fluids
Depending on the measured fluid, the temperature might fluctuate due to pressure fluctuations. Do not use a fluid that
exceeds the operating temperature range at the measurement pressure.
■
Condensation
It will be impossible to obtain sufficient measurement accuracy if there is condensation inside the manometer. If there is
condensation, stop the measurements and fully dry the sensor before continuing. The sensor is at the back of the hose
coupling. To dry it fully, the use of a vacuum dryer, or placement in a high temperature (but still within the operating
temperature range) and low humidity environment using a thermostatic chamber is recommended. There is a risk that
carelessly wiping away water droplets from the vicinity of the sensor could damage the sensor. In addition, there is a risk
of damage if the air blower exceeds the withstand pressure of the sensor.
■Names of Parts
■Operating Procedure
●Preparing the Power Supply
(1) Confirm that the power switch on the main unit is in the OFF position.
(2) Install batteries or connect the AC adapter.
<If Powered by Batteries >
Remove the battery compartment cover from the bottom of the main unit and install two
AA alkaline batteries. Reinstall the battery compartment cover by reversing the battery
cover removal steps above.
•Alkaline batteries will provide about 60 hours of operation, given an ambient temperature of 20 °C.
•Rechargeable batteries can be used. However, due to differences in power output characteristics,
the relationship between the indicated battery level and the corresponding operating time will differ.
Make sure batteries
are oriented correctly.

<If Powered by an AC Adapter (Optional) >
Insert the DC plug from the AC adapter into the DC jack on the back of the main unit. Then insert the AC adapter
plug into the power outlet.
(3) Turn the power switch ON. The battery level indicator will illuminate and the measurement value will be displayed in
the display area.
To display more stable measurement values, let the manometer warm up for about 10 minutes after
switching the power ON.
●Connecting the Tube and Measuring Pressure
Configure tubing connections based on the intended use and then measure the pressure.
•A negative value may be indicated when measuring pressures close to vacuum pressure.
•If you want to perform measurements using your barometer (or standard pressure gauge), refer to “■Calibrating the
Pressure Value” and perform span adjustment prior to measurement. (Zero adjustment is not required.)
•If “Er” or “ER” appears in the display area, there has probably been an instrument failure. Contact your Sibata
representative or distributor.
■Battery Level Indicator
If the battery level indicator is flashing, replace the batteries.
For alkaline batteries, the unit will stop operating about 15 hours after the indicator starts flashing.
■Calibrating the Pressure Value
•When zero adjustment or span adjustment is performed, the factory default calibration is lost. Be aware that this cannot be
restored.
Pressure values can be calibrated using a vacuum pump (capable of pumping 0.01 kPa pressures) and a barometer (or a
standard pressure gauge), prepared separately. Perform zero adjustment and span adjustment in that order. Repeat zero
and span adjustments several times to adjust zero and span.
Place the manometer in an environment conforming to the operating temperature and humidity range (2 to 40 °C, 10 to
90 % RH, no condensation). To display more stable measurement values, let the manometer warm up for about 10
minutes after switching the power ON.
●Zero Adjustment
(1)Connect the vacuum pump to the pressure loading port. Confirm that there is no leakage and then run the pump to
reduce the pressure.
• In this case, a negative value may be indicated, but that is normal.
(2) After the pressure has been reduced sufficiently, adjust the zero adjustment knob on the side of the unit until the
indicated value is 00.0 (kPa).
●Span Adjustment
(1) Open the pressure loading port on the back of the main unit to atmosphere (nothing connected to the port).
(2) Use a barometer to measure the current atmospheric pressure. Then adjust the span adjustment knob on the side of
the unit until the indicated value matches the atmospheric pressure value.
•Note that the indicated value may vary during adjustments, due to atmospheric pressure variations, but that is normal.
Implement countermeasures to prevent foreign matter from getting sucked into the pressure
loading port, when opening the pressure loading port to the atmosphere after the pressure has
been reduced. For example, install a leak valve near the pressure loading port or use a line filter.
Not doing so could cause sensor deterioration or damage.
■Analog Voltage Output
A voltage signal can be output corresponding to the measured voltage by connecting an optional analog output cable
(about 1.5 m long) to the analog voltage output connector on the side of the main unit. The output signal voltage for the
manometer is 0 to 1 V for pressures from 0 to 100 kPa. The white wire is positive and the red wire is negative.
Do not extend the analog output cable.
Connecting an extended length cable to a recorder could cause the indicated pressure value on the main
unit to change (decrease).
Insert the analog output cable plug securely all the way into the connector.
Invalid values could be indicated if the plug is not fully inserted. That does not indicate a malfunction. It
occurs because the signal is temporarily interrupted when the plug is inserted.

■Attaching the Support Column Clamp
The manometer can be mounted to a support column (with a 12 to 15 mm diameter) by attaching an optional support
column clamp to the back of the main unit.
(1) Using a No. 2 Phillips screwdriver, remove the three support column clamp fastening screws from the back of the main unit.
(2) Align the support column clamp mounting holes with the screw
holes from step (1) and install three fastening screws.
(3) Slide the clamp over the column and turn the knob to fasten the
main unit to the column.
Tightly fasten the clamp knob to ensure the
manometer does not wobble. Also make
sure the column itself does not tip over.
■Replacing Hose Connectors
A hose connector (chrome plated brass R1/4 connector with 11 mm O.D. and 6 mm I.D.) is preinstalled
on the pressure loading port at the factory before shipping.
However, the hose connector can be removed and replaced with a connector (prepared separately)
better suited for the given customer application. If so, select a connector that attaches via R1/4 threads.
Be careful to prevent injury from hose connector threads.
Be careful to prevent damaging the pressure loading port from
overtightening the hose connector.
Be sure to use a sealing material (such as PTFE sealing tape) when installing the hose connector.
Not using a sealing material could prevent achieving an airtight seal.
