CABLE TESTER CT100
2
1. INTRODUCTION
Congratulations! With the CT100, you have purchased an indispen-
sable tool that enables you to easily check the most common cables
used by musicians and sound engineers. Faulty cables are a
common cause of failure in live and studio situations. This micro-
processor-controlled device was designed to ensure fast, reliable
problem location. Various test modes and the included belt clip add to
its flexibility.
2. CABLE TESTER MODE
+ Move the ON switch to the CABLE TESTER position.
Insert one end of your cable into any OUT jack of the CT100. Connect
the other end of the cable to any IN jack. The LEDs will indicate which
input pins are connected to each output pin. Additionally, the
GROUNDED SHIELD LED indicates whether a XLR OUT jacks shield
is connected to the pin 1/sleeve signal.
2.1 How to test intermittent connections
The following method allows you to detect intermittent connections
caused by wire breaks or faulty solder points. While in CABLE TESTER
MODE, press RESET to store the current cable-wiring display and to
clear the INTERMITTENT LEDs. Move the cable vigorously in all
directions and watch the LEDs. Any change in wiring or break in the
signal flow will cause the LED of the corresponding input pin to light
up. The LED will stay lit until RESET is pressed again, assuring
detection of even the shortest breaks in the signal flow. It is a good
idea to repeat the test after resetting the LEDs to double-check the
initial results.
