Cable Tester
-
Published in issue 345, July 2005
The basic idea for the cable tester is to apply a different voltage to each conductor in the cable at one end. The voltage seen at the other end of the cable is indicated by light-emitting diodes. The eight reference voltages are generated using a row of nine LEDs connected in series (D1 to D9). The first and the tenth conductors are connected to the positive and negative terminals of the power supply respectively.
