Abstract
The installation of an electrical cable in a building and its subsequent testing are managed by first creating a computer database indicating the type of cable, the location where the cable is to be installed, the performance standard it should meet when installed in that location, and a test regimen to verify compliance with the performance standard. The database is then transferred into a hand held portable test instrument which is placed at the building site and connected to the cable to be tested.
