 OnlyqualiedYOKOGAWApersonnelmayremovethecoversand
disassemble or alter the instrument. The inside of the instrument is
dangerous because parts of it have high voltages.
• Measuring High-Pressure Gases
• Use piping and pressure connectors that can withstand the pressure
to be measured.
• Make sure that there are no leaks from the piping, connectors, and
jointsandthatthejointsarenotloose.Iftheuidundermeasurement
leaks or if a joint comes loose, the pressure can endanger the user or
the surrounding instruments. Note that higher the pressure, greater
the danger.
• Donotmeasureammable,explosive,toxic,orcorrosiveuids.
• Limitation of Pressure
Applying a pressure exceeding the prescribed allowable input can
damage the instrument. In addition, the applied pressure may be passed
on to the device that is connected to the output connector, and cause
secondary accidents.
