Electromagnetic interference can adversely affect the measurement accuracy of
Caution
this product. The input terminals of this device are not protected for electromagnetic
interference. As a result, this device may experience reduced measurement accuracy or
other temporary performance degradation when connected cables are routed in an
environment with radiated or conducted radio frequency electromagnetic interference. To
limit radiated emissions and to ensure that this device functions within specifications in its
operational electromagnetic environment, take precautions when designing, selecting, and
installing measurement probes and cables.
