9. MEASURES AGAINST NOISE
■ 9.1 Effects of Noise
If intermittent changes in measurement values or output are found, or if pressure values different from
actual ones are indicated, they may be affected by noise. Generally, sources of noise include power
supply, an output cable, peripheral equipment, and wiring. Values may be subject to effects of noise
depending on the installation place or position of the product. When you identify the source and take
the measures below, you can reduce effects of noise.
Radiation noise
• Keep the product away from the source
• Change the direction of the product toward the source to change an incidence angle to a board
• Install an electromagnetic shield to the source or the product
• Ground the instrument so that it is electrically connected to earth ground.
Induction noise
• Keep the product away from the wiring carrying high current
• Ground the instrument so that it is electrically connected to earth ground.
• 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
Connect the shield to the earth with a highly noise-resistant cable such as a shielded cable.
•
10. STORAGE
Precautions in storing the instrument are as follows.
Do not store the product in the following locations.
They may cause failure, fire or electric shock.
Locations subject to water
●
Locations where adverse effects may occur due to atmospheric
●
pressure, temperature, humidity, ventilation, sunlight, dust, salt,
sulfur-containing air, etc.
Locations subject to inclination, vibration or shock (including
●
those during transportation)
Locations where chemicals are stored or gases are generated.
●
Locations exposed to direct sunlight or in high-temperature cars
●
Note that storing the product in a sealed bag under a high-
●
temperature or humid environment may deform or discolor the
resin parts of the product.
