3.6 Field Wiring Considerations
When you use the PCI-1710/1710L/1710HG/1710HGL/1711/1711L/
1716/1716L to acquire data from outside, noises in the environment
might significantly affect the accuracy of your measurements if due
cautions are not taken. The following measures will be helpful to
reduce possible interference running signal wires between signal
sources and the PCI-1710/1710L/1710HG/1710HGL/1711/1711L/
1716/1716L.
w The signal cables must be kept away from strong
electromagnetic sources such as power lines, large electric
motors, circuit breakers or welding machines, since they may
cause strong electromagnetic interference. Keep the analog
signal cables away from any video monitor, since it can
significantly affect a data acquisition system.
w If the cable travels through an area with significant
electromagnetic interference, you should adopt individually
shielded, twisted-pair wires as the analog input cable. This type
of cable has its signal wires twisted together and shielded with a
metal mesh. The metal mesh should only be connected to one
point at the signal source ground.
w Avoid running the signal cables through any conduit that might
have power lines in it.
w If you have to place your signal cable parallel to a power line
that has a high voltage or high current running through it, try to
keep a safe distance between them. Or, you should place the
