3.6 Field Wiring Considerations
When you use USB-4711A to acquire data from outside, noise in the environ-
ment might significantly affect the accuracy of your measurements if due cau-
tions are not taken. The following measures will be helpful to reduce possible
interference running signal wires between signal sources and the USB-4711A.
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 sig-
nal cables away from any video monitor, since it can significantly affect a data
acquisition system.
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 sig-
nal source ground.
Avoid running the signal cables through any conduit that might have power lines
in it.
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 place the signal cable in a right angle to the power line to minimize any
undesirable effects.
