8. Measures against Noise

■ 8.1 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 product so that the specified ground point is electrically grounded
(See "4.1 Figure 4-1" and "4.2 Figure 4-2").
Induction noise
• Keep the product away from the wiring carrying high current
• Ground the product so that the specified ground point is electrically grounded
(See "4.1 Figure 4-1" and "4.2 Figure 4-2")
• 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 high-noise-resistant cables such as a shield one for connection to connect the
shield to the ground

9. Storage

■ 9.1 Precautions for Storage
Do not store the product in the places listed below.
If you do not observe this instruction, the product will fail or get
damaged.
 A place subject to water.
 A place that may be adversely affected by atmospheric
pressure, temperature, humidity, ventilation, sunlight, dust,
and air including salt or sulfur content
 A place with inclination, vibration, and shock (including shock
during transportation)
 A storage location of chemical agents, or a place where gas is
generated
 A place exposed to direct sunlight, or inside a car at high
temperature
