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 measure-

ments

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 inter-

ference. 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 dis-

tance

between them. Or place the signal cable in a right angle to the

power line

to minimize the undesirable effect.
