Noise Test
The test tool periodically checks for excessive electrical noise on the cabling under
test. Noise sources include nearby electrical equipment and transmitters and live
network transmissions on adjacent cables. If excessive noise is detected, the test
tool displays Noise Detected and automatically attempts to filter the noise
to meet published accuracy specifications. If the test tool cannot filter out all the
noise, and you save the test results, the test report will include the message
“WARNING Excessive noise detected. Measurement accuracy may be degraded”.
To stop the test and return to the first screen of the selected test mode, press e.
