Test-Um NT955 User Manual

Test-Um NT955 Series
If neither voltages nor Ethernet is detected, Validator-NT searches for its

remote to run a cable test. If the remote is found, a manual mode cable

test is run and the remote ID, wiremap, full Signal to Noise Ratio, and

Skew test results (1000Mbit only) are displayed. Speed testing, as well

as placing tone on a cable, is performed in the Manual Test mode of the

Validator-NT only. If a remote is not found, a one-ended test for shorts

and split pairs is run and the results are reported.
