Induction noise
• Keep the product away from the wiring carrying high current.
• Keep the product away from electrically charged machines or objects.
Conductive noise
• Use the stable power supply that is difficult to generate noise.
• Install power supply or output measurement equipment in an environment that is impervious to
being affected by noise.
• Use a ferrite core to filter cables.
• Use high-noise-resistant cables such as a shield one for connection to connect the shield to the
ground.

12. MAINTENANCE
■
12.1 Periodical Inspection
A periodical maintenance once a half year will be needed due to possible aging under different
operating conditions. Also, perform calibration as needed. Calibration should be performed in a
specified manner or at a designated calibration laboratory.
Refer to the following checklist for periodic inspections.
< Periodic Inspection Checklist >
・
Appearance (flaws, cracks, deformation, and corrosion)
・
Corrosion state of the pressure inlet
・
Insulation resistance between the case and all terminals tied
(100 MΩ or more
at 50V DC)
・
Leak check and retightening of the threads
・
Output check with a reference pressure gauge and a measuring instrument
・
Waterproof check and retightening of the cable, gland, and terminal box
