Instruction Manual
Ver.5.0
These products (pressure sensors, pressure switches, pressure gauges, pressure indicators, leakage sensors,
etc.) are designed and manufactured as general industrial parts. Therefore, a person with sufficient knowledge
and experience shall confirm the conditions and environments described in the catalog, specifications, and
instruction manual of each product, check the suitability of the product for the machine, device, or system which you use,
and ensure safety before use.
These products are not intended to be used for applications particularly requiring high reliability (These include, but are
not limited to, nuclear power control, aerospace and military purposes).
The details of warranty shall be as per the descriptions in this document and we shall not be liable for any damage on you

party in connection with such use in violation regardless of the name by which such payment may be called, we may
demand the whole amount thereof from you.
①This product is a pressure indicator which displays the detected pressure by connecting a pressure sensor with a
built-in amplifier and setting the rated pressure range of an applicable sensor. Since the product type differs
according to the specifications (voltage and current signals) of each sensor, use it with appropriate combinations.
②The power voltage applied to this product is used as the drive voltage for the sensor connected. Therefore, make sure
the power requirements of the sensor and use it within the allowable specification range.
③Make cable wiring when the power is turned OFF. Be careful to mis-wiring and non-wiring, it may damage the product.
④Use a stable DC power supply. For the relay, solenoid, or other inductive loads used on the same power circuit with
this product, use an appropriate surge absorption element （diode, varistor, etc.） （ Refer to the figure at right.）
⑤The protection structure of this product conforms to IP40 of IEC standards or equivalent. The product is not suitable
for use in dust- and drip-proof environments requiring higher standards. In
addition, since it does not have an explosion proof structure, do not use it
in flammable gases.
⑥Do not pull the cable with a force of 40N or more when handling this
product, as this may disconnect the cable or damage the product.
⑦Do not use pointed objects such as pens to press the setting buttons on
the display panel.
