Test-Um NT955 operating instructions Un-powered Ethernet Test

Test-Um NT955 Series ValidatorTM Network Tests

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.
