IX. RJ11 Cable Validating
1. Insert the RJ11 plug of the cable under test into the RJ11 jack of the
transmitter, or use the RJ11 alligator clip adapter cable to connect the
transmitter and metal cable under test.
2. Press the button, the button flashes, and the validating function is
enabled.
3. The CONT indicator lights up green to indicate open circuit of the cable,
and red to indicate short circuit of the cable. The POLARITY indicator lights
up green to indicate that the cable has a positive polarity voltage, red to
indicate that the cable has a reverse polarity voltage, and green and red
flash alternately to indicate a ringing signal or AC power on the cable.
X. Other Functions
1. NCV Function
Press the NCV button to enable the NCV function. When the target cable
or socket has an AC voltage over 40V, the receiver will beep and the NCV
indicator will flash synchronously.
If the target cable are intermixed with massive cables, turn the sensitivity
knob to adjust the sensitivity. Louder sound means stronger signal and closer
to the target cable.
VIII. RJ45 Cable Validating
1. Insert the RJ45 plugs of the cable under test into the RJ45 jacks of the
transmitter and receiver.
2. Press the button, the button flashes, and the validating function is
enabled.
3. Judge the state of the cable (good wiring, short circuit, open circuit, miswire)
according to the line sequence indicators on the transmitter and receiver.
4. During test, press the button to switch between fast and slow mode.
5. The diagram below shows the wiring of different states (good wiring, short
circuit, open circuit, miswire) for unshielded cables.
• Good wiring: LEDs (1~8) on the transmitter and receiver light up in turn.
• Short circuit: No.3 and No.4 LEDs on the receiver light up simultaneously
with dim brightness.
• Open circuit: No.3 LED of the transmitter and receiver do not light up.
• Miswire: LEDs of the transmitter and receiver do not light up correspondingly.
2. Flashlight
Press the button to turn on/off the flashlight of the receiver.
3. Low Battery Indication
1) When the battery voltage
≤
3.4V, the power button will flash.
2) When the battery voltage
3.0V, the device will automatically shut
down and need to be charged.
4. Earphones
In noisy environments, users can wear earphones during operation
(earphones need to be prepared by users). Volume can be adjusted by
turning the sensitivity knob.
