Influence of Cable Length
When the instrument is incorporated in a production line or automated machine, the
measurement cable may be extended. When the measurement cable is extended,
measured values can be affected by coupling capacitance between cables or line
noise. The level of influence on measured values when the measurement cable is
extended is shown below.
For the influence of a capacitive load, refer to “Appx. 4 Influence of Capacitive Load”
(p. Appx.4). For the influence of line noise, refer to “Appx. 6 Influence of Noise” (p. Appx.7).

Cautions for measurement cable wiring
• When the measurement cable is laid on a metal ground, the influence of noise can be reduced.
• When the measurement cable is extended, the influence of power line noise becomes more
significant. Position the measurement cable away from the power line.
•
Position the measurement cable away from any noise sources (motor, welder, inverter, etc.).
