7 CABLE TESTER CT100 User Manual
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 ow,
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 ow.
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 ow 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 aect
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, O = 440 Hz.
