Tests for: | Opens |
| Shorts |
| Intermittents |
| Crossed wires |
DESCRIPTION
The CT 1 consists of two RCA jacks, two 1/4" jacks, two female XLR, two male XLR jacks, and two MIDI jacks.
LED 1/GND: Indicates continuity between pins 1 of an XLR cable or MIDI cable, or ground on an RCA or 1/4" cable.
LED 2/TIP: Indicates continuity between pins 2 of an XLR cable, or the tip on an RCA or 1/4" cable.
LED 3/RING: Indicates continuity between pins 3 of an XLR cable or MIDI cable, or the ring of a 1/4" cable.
OPERATION
Insert one end of the cable to be tested on the left side of the line, located in the middle of the CT 1, and the other side of the cable on the right side of the line. See example below.
To test RCA and 1/4" TS cables, plug each end of the cable into the proper jack and wiggle the cable around at different points on the cable. Watch the 1 and 2 LEDs, if either LED is off, or goes on and off - the cable is bad.
The testing procedure for 1/4" TRS (stereo) and XLR cables is identical to the above, except watch the 1, 2 and 3 LEDs.
Adapter type cables, such as 1/4" to XLR cables, may also be tested by plugging each end into it's proper jack on either side of the line. Test as indicated above.
To test a MIDI cable, plug each end of the cable into the MIDI jacks and test as described above. Watch the 1 and 2 LEDs, if either LED is off, or goes on and off - the cable is bad.
NOTE: WHEN TESTING A 1/4" MONO TO RCA CABLE, CONNECT THE 1/4"
PLUG TO THE LEFT 1/4" JACK AND THE RCA TO THE RIGHT RCA JACK. DUE TO A PARTICULAR CIRCUIT CONSIDERATION, TESTING VICE VERSA (WITH THE 1/4" ON THE RIGHT AND THE RCA ON THE LEFT) WILL BE INACCURATE.
