Connect one end of the test cable to the
appropriate SEND connector and the other end to
the mating RECEIVE connector. Turning the
rotary switch from the OFF position will send
current to one of the SEND LED indicators and to
the same contact on the SEND connector. The
current flows through the cable and into the
RECEIVE connector and will light the
corresponding RECEIVE LED in a cable wired to
the same contact at each end. For cables wired
pin to pin, rotating through all of the positions
should light only SEND and RECEIVE LEDs for
the conductor that the switch is testing. Cables
with shorted conductors will light additional SEND
and RECEIVE LEDs identifying which wires the
conductor being tested is shorted to. Cables with
open conductors will light only the SEND LED.
Combinations of shorts and opens will light
patterns of LEDs that can identify the fault
conditions within the cable. The SC48 can also
identify custom wiring configurations.
Operation
Removing the six case screws provides access to
the 9 Volt battery compartment. The battery
should be changed when the SEND LED
becomes dim.
