Using a measuring instrument in an environment with radiation noise

	Common problem on site
When a power line or a motor inverter is present near a sensor cable or an output signal cable, radiation noise may transmit through these cables. Radiation noise propagates through the air. The radiation noise transmitting through the cable may interfere with the measurement, resulting in unreliable data.

Using a measuring instrument in an environment withextraneous light

	Common problem on site
The measurement data may fluctuate when a hot, glowing object is measured or when the receiver receives extraneous light such as the beam of a laser-welding machine.

Using a measuring instrument in special environments

	Common problem on site
High temperature or vacuum. In manufacturing processes, measurement must often be conducted in special environments such as high temperature or a vacuum. Such extreme environments are also used to investigate the characteristics of products. Normal precision instruments, however, cannot be used in such environments.

Measurement by ignoring flaws

	Common problem on site
Displacement meter When slow changes are measured such as a change in thickness, abrupt change, such as vibration or flaws, may interfere with accurate measurement.
