where they exit from the apparatus.

11. Use only attachments/accessories

specied by themanufacturer.

12. Use only with the cart,

stand, tripod, bracket,
or table specied 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 qualied 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.

15. The apparatus shall be connected to

a MAINS socket outlet with a protective
earthing connection.

16. Where the MAINS plug or an appliance

coupler is used as the disconnect device,
the disconnect device shall remain readily
operable.

1. Introduction

Congratulations! With the CT100, you have purchased an indispensable tool that
enables you to easily check the mos t common cables used by musicians and sound
engineers. Faulty cables are a common cause of f ailure in live and studio situations.
This microprocessor-controlled device was designed to ensure f ast, reliable problem
location. Various test modes and the included belt clip add to its exibility.

2. Cable Tester Mode

◊ Move the ON s witch to the CABLE TESTER posi tion.

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
connecte d to the pin 1/sleeve signal.

2.1 How to test intermittent connections

The following method allows you to detect intermittent connections caus ed by wire
breaks or f aulty solder points. While in CABLE TESTER MODE, press RESET to store the
current cable-wiring display and to clear the INTERMIT TENT LEDs. Move the cable
vigorously in all directions and watch the LEDs. Any change in wiring or break in the
signal ow will cause the LED of the cor responding input pin to light up. TheLED will
stay lit until RESET is pressed again, assuring detection of even the shortes t breaks in the
signal ow. It is a good idea to repeat the test after resetting the LEDs to double-che ck
the initial results.

3. Installed Cable Tester Mode

This mode enables you to test cables in xed installations or situations that don’t allow
you to connec t both ends of the cable to the C T100.

◊ Hold down the RESET but ton while moving the ON s witch to the CABLE TESTER

position. The ON LED will blink to indicate that th e CT100 is in INSTALLED CABLE
TESTER MODE.

7 CABLE TES TER CT100 User Manual

To test a cable for sho rt circuits, connect one end of the c able to the appropriate
OUT jack of the C T100. The display work s 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 continuit y 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 break s in the signal ow,
the display will show the corresponding pins as being sho rted to each other. If the display
indicates no short circuit, there is a break in the signal ow.

◊ The tes ting of intermittent connections works exactly as in C ABLE TESTER MODE

(see chapter 2.1).

◊ INSTALLED CABLE TESTER MODE will not indic ate connections between out an d

in pins. Thi s is done in CABLE TESTER MODE (see ch apter 2).

4. Test Tone Mode

◊ Move the ON s witch to the position TEST TONE.

◊ Do not use the TEST TONE MODE for MIDI cables!

TEST TONE MODE may be used to check signal ow and to facilit ate level adjustments.
It routes a tes t tone to the “+ pin” (pin 2/tip) of all OUT jacks. Use the TEST TONE LEVEL
switch to cho ose 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 aect
the test tone output level.

4.1 Selection between 1 kHz and 440 Hz

While in TEST TONE MODE, pressing RE SET toggles between 1 kHz and 440 Hz. The TE ST
TONE LED indicates the selected frequenc y: On = 1 kHz, O = 440 Hz.

8 CABLE TES TER CT100 User Manual

5. Phantom Power Detect

In TEST TONE MODE, pins 2 and 3 are monitored for exter nal DC voltage
(common ly supplied for condense r micropho nes). The PHANTOM LEDs will light if DC
voltage above approx. 9 V is detected.
