OPEN CIRCUIT

, the corresponding LEDs will remain unlit. See Fig. 1d.

LEAKAGE BETWEEN WIRES

, the LEDs of the pins being tested will light, 

also other LEDs will light with lesser intensity. The intensity with which these other 
LEDs will light is proportional to the leakage between wires. The MCT-7 Cable Tester 
will show leakage up to 10K

 between wires. See Fig. le.

SHORT BETWEEN WIRES

, the LEDs of the pin being tested will light, also 

other LEDs will light (for the wires in short). See Fig. 1f.

SHORT TO GROUND

, the LEDs of the pin being tested will light as well as 

the Ground LED (Red and indicated with a “G”). If more than one LED lights at the same
