9. OPERATION (ENERGIZATION)

Before powering on, make sure once again that the correct connections are established and that the
rated voltage/current of the power supply as well as the internal resistance of the externally
connected equipment are within the rated range of the load resistance applied to the product. Then,
power on and wait at least 5 minutes for warm-up before starting a production run.

10. MEASURES AGAINST NOISE

■10.1 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 in the source or the product.
surge or other phenomena, a varistor or the like should be connected to
protect the transmitter.
 Before installation, check the rated value specified for this
product to determine the rated value of the power supply to use.
Internal resistance of equipment to be connected should be
within the rated load resistance of the product.
Observe the following precautions during operation:
 Avoid applying pressure equal to or higher than the rated
pressure shown on the product label.
 Do not conduct wiring in the power-on state. Failures or electric
shocks may be caused in the product. Follow the wiring diagram
to install the cables.
 Before installation, check the rated value specified for this
product to determine the rated value of the power supply to use.
Internal resistance of equipment to be connected should be
within the rated load resistance of the product.
