3.5 Field Wiring Considerations
• When you use USB-4761 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 USB-4761.
• 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.
• 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.
• 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 the undesirable effect.
