Piping
• When using this product, connect a joint available in the market
to the pressure port. At the time, the tightening torque should be
1.0 N·m or less.
Mounting
• Use sensor mounting bracket MS-DP1-1 prepared
independently.
When mounting this product with sensor mounting bracket, etc.,
the tightening torque should be 0.5 N·m or less.

(Optional)
• Panel mounting bracket MS-DP1-8 (optional) and front protection
cover MS-DP1-3 (optional) are available.
• For the method for mounting panel mounting bracket, refer to the
instruction manual that came with the MS-DP1-8.
Wiring
• Make sure that the power supply is OFF while performing the
wiring operation.
• Verify that the supply voltage variation is within the rating.
• If power is supplied from a commercial switching regulator,
ensure that the frame ground (F.G.) terminal of the power supply
is connected to an actual ground.
• In case noise generating equipment (switching regulator, inverter
motor, etc.) is used in the vicinity of this product, connect the
frame ground (F.G.) terminal of the equipment to an actual
ground.
• When extending the cable, use a cable whose conductor cross-
section area is 0.3 mm

in total length.
• Do not run the wires together with high-voltage lines or power
lines or put them in the same raceway. This can cause
malfunction due to induction.
• Do not apply stress directly to the connection cable leader or to
the connector.

How to connect
• Insert the cable with connector
CN-14A(-R)‑C□ into this product's
connection connector section as shown
in the right figure.
How to disconnect
• Pressing the release lever of the cable
with connector, pull out the connector.
Note: Do not pull by holding the cable without pressing the release lever, as
this can cause cable break or connector break.

Description
The load is short-circuited
causing an overcurrent to
flow.
Pressure is applied during
zero point adjustment.
The applied pressure
exceeds the upper limit of
the displayed pressure
range.
The applied pressure
exceeds the lower limit
(back pressure) of the
displayed pressure range.
When other error massage is displayed, contact us.
Others
• This product has been developed / produced for industrial use
only.
• The product shall be used only within the rated pressure range.
• Do not apply pressure exceeding the pressure resistance.
Otherwise, destruction of diaphragm occurs, preventing the
product to perform normal operation.
• Do not use during the initial transient time (0.5 sec.) after the
power supply is switched ON.
• The specification may not be satisfied in a strong magnetic field.
• This product is suitable for indoor use only.
• Take care that strong impact such as fall is not given to this
product. Otherwise, it may be destroyed.
• Avoid dust, dirt, and steam.
• Take care that the product does not come into contact with
organic solvents such as thinner.
• Take care that the product does not come into contact with oil or
grease.
• Take care that the product does not come into contact with
strong acid or alkaline.
• Do not insert wire into the pressure port. Otherwise, destruction
of diaphragm occurs, preventing the product to perform normal
operation.

Remedy
Turn OFF the power and
check the load.
Applied pressure at the
pressure port should be
brought to atmospheric
pressure and zero-point
adjustment should be done
again.
Applied pressure range
should be brought within
the rated pressure range.
