① The applicatable pressure medium of PG-20 gases and liquids compatible to SUS316L.
② For stability, use a regulated direct current power supply.
Please earth the terminal FG when you use the switching power supply.
③ Surge absorbing devices（diodes, varistors, etc.）are necessary if inductive loads such as relays or solenoids are connected to the same circuit to PG-20.
④ Turn off the power while wiring. Also, please do not mis-wire.
⑤ Do not wire parallel to a high tension cables or power lines, or use cable ducts containing high tension or high power.
⑥ Cables connectors should be removed from the product while piping. The product can be damaged if the connected cable is pulled at 20N or more. In
addition, the display rotation part can be damaged when turning the display at 0.3N・m or more.
⑦ Clean the product with the cloth that contains a small amount of pure water or alcohols solvent when the product is dirty. The cleaning solution must
never enter into the product. It may cause an internal circuit breakdown.
⑧ This product is dust proof and drip proof（to IP40 of IEC standards）and is not suitable for use in environments requiring higher standards.
⑨ Do not use pointed objects such as pens to press the setting buttons on the display panel, as this may push holes in the setting buttons and damage
them.
⑩ Do not insert wires, etc. in the pressure port, as this may damage the internal diaphragm and cause malfunctioning.
⑪ Do not touch or scratch the edge of the fitting, as this may damage the sealing and cause leakage.
⑫ The PG-20 series is not explosion proof. Do not use it for the detection of flammable gases.
⑬ When analog output is supplied to a noise-sensitive device, a low-pass filter is requested in a customer's circuit.
⑭ For EMC measures, please earth the power supply. Also, please connect the fitting block to an earthed metalic casing or to the ground. This product can
not resist thunder surge, therefore please do not use this product at unprotected outdoors or extend the cable to 30m or more.
