To generate test tones through any of the OUT jacks (except the MIDI out), move

the On switch to the Test Tone position.

CABLE TEST MODE:

To use Installed Cable Test mode, hold down the Reset button while moving the

On switch to the Cable Test position. The Power ON LED will blink to indicate the

unit is in Installed Cable Mode.

3) Test Tone Mode:

The 6-in-1 Cable Tester works in three main modes of operation:

1) Cable Test Mode:

To use, move the On switch to the Cable Test position.

2) Installed Cable Test Mode:

The 6-in-1 Cable Tester works with six different types of connectors: XLR, 1/4"

(mono or stereo), RCA (also called phono), 1/8" (mono or stereo), TT, and 3 pin

MIDI. Some MIDI devices now use more that 3 pins but the cable tester will only

check 3 pins.

Included in package: 1 Cable Tester with 4 rubber feet attached.

Not Included: 2 AA batteries. Install batteries via the battery door on the

underside of tester. Remove the battery door phillips head screw for battery

access.

PHANTOM POWER DETECT: During Test Tone Mode, pins 2 and 3 are monitored for

external DC voltage as commonly supplied to microphones. The Phantom LEDs will

light any time the presence of a DC voltage greater than 5V is detected.

between signals in the cable, then none of the LEDs in the Cable Wiring Display will

light. Next, place a shorting jack on the other end of the cable. If the signals in the

cable have no opens, then they'll make it all the way to the shorting jack and the

Cable Wiring Display will show all pins as being shorted to each other. The display

Disconnect both ends of a suspect cable from the equipment it is attached to.

Attach one end of the cable to the appropriate Output jack and leave the other end

disconnected. The Cable Wiring Display works as before except it now shows any

connections between OUT pins, not between OUT and IN pins. If there are no shorts

to the Test Tone position.

Warning: DO NOT use Test Tone Mode for MIDI cables. The cable tester does not

generate MIDI data. While we won't guarantee it, the audio test tone should not

harm MIDI equipment if connected.

A test tone is placed on the Pin2 / Tip signal of all OUT jacks. The level can be set to

either +4 dBu, -10 dBV, or Mic level (approximately -50dBV). Note that battery

voltage level will effect the accuracy of the test tone output level. The Test Tone

Mode is intended for use in checking audio system integrity and the rough setting of

signal levels only and not for use as a voltage standard.

1kHz / 440Hz Selection: Pressing Reset during Test Tone Mode will switch the test

tone frequency between 1kHz and 440Hz. The selection is indicated by its LED: On

= 1kHz, Off = 440Hz. Test tone frequency accuracy is +/- 0.1% and is unaffected

by battery voltage.

TESTING FOR INTERMITTENT CONNECTIONS:

While in Cable Test Mode, pressing Reset stores the current Cable Wiring Display

and clears the Intermittent LEDs. If any change occurs in the wiring displayed, the

Intermittent LED corresponding to any Input pin which had the change will light and

stay lit until the next time Reset is pressed. In this way you'll know if you have an

intermittent cable even if it was intermittent for such a small period of time that you

may have not seen the LED flicker.

INSTALLED CABLE TEST MODE:

To use Installed Cable Test mode, hold down the Reset button while moving the On

switch to the Cable Test position. The Power ON LED will blink to indicate the unit is

in Installed Cable Mode.
