3. HIRO054 01 User s Manual of Small Pressure Sensor VUS12 Series Thank you for purchasing PISCO small pressure sensor In order to safely handle the sensor please be sure to read and understand this User s Manual before using it Please keep this manual handy with care so you can refer to this manual as necessary Safety instructions are classified into danger warning and cautions depending on the grade of damage or danger involved when the safety instructions are not complied with in handling ND Failure to heed the warning of apparent danger may result in death or anger serious injuries INW i Failure to heed the warning of conditionally dangerous situations may arning result in death or serious injuries A ti Failure to heed the warning of conditionally dangerous situations may au lon result in minor or not too serious injuries or damage to properties A Warning The sensor must not be used in the atmosphere or gas where corrosive substance is dissolved To do so can cause damage to the sensor Avoid using the sensor in the inflammable and explosive gas liquid or atmosphere The sensor is not designed as explosion proof and may cause fire or explosion A Caution The sensor is for air or inert gases An applied or impressed wiring such as with noise may cause functional failure of the sensor Make sure that the power supply is turned off when wiring Make sure of the color of the lead wires and terminal numb
