Sources of System Cabling Errors

Radio Frequency Interference Most voltage-measuring instruments

can generate false readings in the presence of large, high-frequency

signals. Possible sources of high-frequency signals include nearby radio

and television transmitters, computer monitors, and cellular telephones.

High-frequency energy can also be coupled to the internal

DMM on the

system cabling. To reduce the interference, try to minimize the exposure

of the system cabling to high-frequency

RF sources.

If your application is extremely sensitive to

RFI radiated from the

instrument, use a common mode choke in the system cabling as shown

below to attenuate instrument emissions.
