• The Continuity testing lamps of the transmitter: 1-2-3-4-5-6-7-8
• The REMOTE lamps of the transmitter: 1-2-3-4-5-6-7-8
• Short circuit: Take the short circuit of lamps 2 and 5 as an example. When the Continuity testing lamps 2 and 5 of the transmitter light up, the REMOTE Continuity testing lamps 2 and 5 light up at the same time, but the brightness is darker.
• Open circuit: Take the open circuit of lamp 2 as an example. When the Continuity testing lamp of the transmitter lights up, both the transmitter Continuity testing lamps and the REMOTE Continuity testing lamps don’t light up.
• The Continuity testing lamps of the transmitter: 1-X-3-4-5-6-7-8
• The REMOTE lamps of the transmitter: 1-X-3-4-5-6-7-8
• Crossing: Take the crossing of lamps 2 and 5 as an example. When the Continuity testing lamp 2 of the transmitter lights up, the REMOTE Continuity testing lamp 5 lights up.
• The Continuity testing lamps of the transmitter: 1-2-3-4-5-6-7 -8
• The REMOTE lamps of the transmitter: 1-5-3-4-2-6-7-8

Continuity testing for the switch router:

• It is mainly used to detect the connection and disconnection of the network cables. Insert one end of the network cable into the Continuity testing /tracing interface at the top of the transmitter, and the other end into the switch or router.
• If the tested 8-cable network cable or the pin port of the equipment is in normal condition, the indicator lamps 1-2-3-4-5-6-7-8 will light up one by one. If the 2nd cable of the network cable is broken, the indicator lamps 1-3-4-5-6-7-8 will light up.
• Note: This method can also apply to the Continuity testing of POE switches. However the quality of POE switches of various brands in the market is different, it is not suitable for this test method if the POE/ POE module/POE power supply is sub-standard.

Connection test of POE power supply cables

• One end of the network cable is inserted into the RJ45 interface at the bottom of the receiver and the other end into the working POE switch. The test results are as follows:
• If lamps 1/2 or 3/6 in the test light up, it is indicated that the power supply mode of this POE switch is the terminal bridging connection (1 /2- or 3/6-cables power supply).
• If lamps 4/5 or 7/8 in the test light up, it is indicated that the power supply mode of this POE switch is the intermediate bridging connection (4/5 or 7/8 cables power supply).
• If lamps 1/2 3/6+4/5 or7/8 in the test light up, it is indicated thatthe power supply mode of this POE switch is an 8-cable power supply.
• Note: In the above description, the pin cable with a lamp lighting up is positive.

QC testing function

• Short-press the transmitter to enter the QC testing mode.
• Insert one end of the network cable or telephone cable into the QC testing interface on the side of the transmitter, and the other end is not connected to anything.
• The device can automatically identify and indicate the currently detected pressure connecting the network cable connector.
• If the QC testing indicator lights up, it is indicated that the pressure connecting the corresponding cable contained in the network cable is in good condition; If the cable pressure indicator doesn’t light up, it is indicated that the pressing connection of the corresponding cable is abnormal.

For example:

Network cable:

1. Being in good condition: the result of transmitter QC testing is shown as 1 2 3 4 5 6 7 8
2. Take the bad pressure connecting of cable 2 as an example. The results of transmitter QC testing are as follows

Telephone cable:

1. 6P6C is in good condition
2. 6P4C is in good condition:
   • 6P2C is in good condition:
   • Note: the QC testing function is mainly used to detect whether the connection of the network cable connector is normal, but it cannot judge whether the cable sequence is correct.
   • If it is necessary to test the cable sequence, apply the Continuity testing function for the testing.

Connection function

• In any mode, press the button to start the connectivity test function.
• Insert the connector of the connection cable with two alligator clips into the RJ11 interface, and the two alligator clips respectively clamp the two ends of the cable to be tested.
• If the cable is properly connected, the connectivity indicator lights up, and the brightness of the indicator will change with the degree of impedance on the cable. The brighter the indicator, the smaller the impedance.
• Note: Do not connect to high-voltage cables for testing, otherwise the device will be damaged.

NCV

• Short-press the button of the receiver to enter the NCV test mode, and the NCV indicator lights up. Let the receiver probe get close to the cable or socket or other probed parts. If 40V AC is found, the receiver will send out the”beep” sound.
• Note: The chargers usually belong to the switching power supply through voltage transforming and frequency converting, the recharging cable is coupled with a high-frequency AC voltage signal, so, normally, the AC voltage can be detected at the time! In addition, it is normal that the buzzer gives an alarm when the probe is approaching the power transformers, induction cookers, etc.

Lighting

• Short-press the utton of the receiver to turn on the LED flashlight of the receiver, and short-press the button again to turn it off.

headphone of the receiver

The function of the headphones: when carrying out the testing in a noisy environment, put on the headphones for operating to avoid external interference.
