A9: Because the wiremap test results of Nf-308 are displayed in pairs. Therefore, PIN1 & 3 disconnection will display PIN 1 & 2 & 3 & 6 disconnection, PING 1 & 2 short circuit will display PIN 1 & 2 short circuit, and PIN 3 & 5 disconnection will display PIN 3 & 4 & 5 & 6 disconnection.

Q10: What are functions of NF-308? 

A10: 1. Measure the length of the network cable, which can be calibrated, stored and retrieved;
2. Find network cable, telephone cable, BNC cable, USB-A cable and ordinary metal cable;
3. Test open, crossover, and short-circuit status of the network cable and BNC cable. This machine can determine which end of the crystal head is not done well when wiremap testing;
4. With POE hunting mode, port flashing function, Telephone line voltage test, positive and negative test function.

Q11: What is the hunting mode of the NF-308? Can it be loaded with 4-core cable? Can it be hunted on a gigabit switch? 

A11: The NF-308 has a anti-interference ability when hunting, and it is very accurate in the cable-intensive occasions.
However, there is no sound when hunting on 4-core cable is loaded or on gigabit switch.

Q12: The value can be saved after NF-308 is turned off after the length calibration? Measure the length after turning it on again. Is it the default parameter or the calibrated parameter?
