1. Introduction

Congratulations! With the CT100, you have purchased an indispensable 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 microprocessor-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 jack’s 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.

3. Installed Cable Tester Mode

This mode enables you to test cables in fixed installations or situations that don’t allow you to connect both ends of the cable to the CT100.

  • Hold down the RESET button while moving the ON switch to the CABLE TESTER position. The ON LED will blink to indicate that the CT100 is in INSTALLED CABLE TESTER MODE.

To test a cable for short circuits, connect one end of the cable to the appropriate OUT jack of the CT100. The display works as in CABLE TESTER MODE (see chapter 2). However, it now indicates connections between out pins. If no LEDs light, the cable is free of short circuits.

3.1 Continuity check in Installed

Cable Tester Mode
For a continuity check, connect a shorting jack (a jack in which pins are short-circuited to one another) to the other end of the cable.
If there are no breaks in the signal flow, the display will show the corresponding pins as being shorted to each other. If the display indicates no short circuit, there is a break in the signal flow.

  • The testing of intermittent connections works exactly as in CABLE TESTER MODE (see chapter 2.1).
  • INSTALLED CABLE TESTER MODE will not indicate connections between out and in pins. This is done in CABLE TESTER MODE (see chapter 2).

4. Test Tone Mode

  • Move the ON switch to the position TEST TONE.
  • Do not use the TEST TONE MODE for MIDI cables!

TEST TONE MODE may be used to check signal flow and to facilitate
level adjustments. It routes a test tone to the “+ pin” (pin 2/tip) of all OUT jacks. Use the TEST TONE LEVEL switch to choose between +4 dBu, -10 dBV, or -50 dBV mic level. Please note that this mode is not intended to work as a voltage standard and that battery voltage will affect the test tone output level.

4.1 Selection between 1 kHz and 440 Hz

While in TEST TONE MODE, pressing RESET toggles between 1 kHz and
440 Hz. The TEST TONE LED indicates the selected frequency: On = 1 kHz, Off = 440 Hz.

5. Phantom Power Detect

In TEST TONE MODE, pins 2 and 3 are monitored for external DC voltage (commonly supplied for condenser microphones). The PHANTOM LEDs will light if DC voltage above approx. 9 V is detected.

Important Safety Instructions

1) Read these instructions.
2) Keep these instructions.
3) Heed all warnings.
4) Follow all instructions.
5) Do not use this apparatus near water.
6) Clean only with dry cloth.
7) Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
9) Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10) Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
11) Only use attachments/accessories specified by the manufacturer.
12) Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13) Unplug this apparatus during lightning storms or when unused for long periods of time.
14) Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
