6-in-1 Cable Tester Instructions
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.
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.
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: 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: 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 test if the cable is good, set to "Cable Test Mode". Insert
both ends of cable into appropriate jacks (in/out).
· Balanced 1/4" (TS or TRS), 1/8" (TS & TRS), XLR, MIDI (3 pin)
and TT cables will read as a big check mark if cable is good.
· If the LED's look anything other than in diagrams below, there
is a cable fault. The additional LED's that light up indicate which
wires have the fault.
· To test for an intermittent short in a cable, insert one end of the
cable into the IN jack of the cable tester and set it to "Cable Test
Mode". Press the reset button to make sure it's clear. Move the
cable around. If there's an intermittent short in the cable, the
LED corresponding to the shorted wire will light up and stay lit
until you press the reset button. Checking again would verify
your findings.
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.
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 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 does not show a pin
shorted to itself. The Intermittent testing feature works in the
same way as Cable Test Mode.
TEST TONE MODE: To generate test tones through the OUT
jacks, move On switch 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 Pin 2 / 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.
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.
WIRING DISPLAY / GROUNDED SHIELD DETECTOR: The
Cable Tester has a handy LED grid that can be used to show how
a cable is wired. This can be especially handy to determine is an
XLR cable has the ground connector to the connector housing.

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.
