Awesome video where it picks right up from some details missing on the manual. :)

I ordered mine last week ago and it arrived yesterday! Mine is version 3 Blue! I AM EXCITED TO TEST IT!

[VideoProductioninc]

When you have bad sound, don't add music !

[MartArmstrong]

Great vid and very helpful. But that music is awful while trying to listen to the presenter

[MixedArarash]

why there are so may remote for this device?

[amgari]

Music is higher than the voice. we need the voice.

1) How do you use the USB cable test function? 2) Can the RJ11 port be used to test RJ11-terminated cables (e.g. telephone cables) or just for polarity testing? I'm not really sure where using a RJ11 connector to test polarity is useful? If it can be used to test RJ11 cables, how do you use the tester to test them? Thank you.

Did shows which side (meter or remote) has pins reverse(crossover)?

[brechtverschaeren]

Hello, the nofaya nf-388 shows up by scanning UTP all 8 ID's from the remote's on the screen?

[dr.anthonrijkardcortes]

Question, I have a renovation that has a ton of network cables, a ton of power cables and telephone lines and a door bell system. I have to figure out where all the cables go, or where do they come from. Most of the network cables are labeled, but the power cables and the door bell system are not. Worse off, I have to rewire some rooms for power from one breaker switch panel to another. So, can this unit help me? Mainly I need to ID cables in the rooms throughout the building (several even in different floors) to where they are connected in the electric breakers panel in the basement. I know that I need to have a cable disconnected from the electric power grid and the switches off to properly ID each line, but, could I connect the 8 remote units in the rooms, then go to the panel downstairs and ID each remote unit in the basement?

[CraigFogus]

I have the NF-388 with the port flash option. When I set the unit to feet instead of meters, it does not remember this setting after powering off then powering back on.

I bought a noyafa NF-308, but it turns out that after being hit by a PoE switch it turns off, what is the solution??

[a]

你好 為何我5M短線接上測試會顯示短路？ 跟你影片內接MAIN 另一端接Port FLASH 顯示的不一樣
NF-308 直接接Switch 也會顯示短路
機種：NF-308 韌體：V_6.8

[xampleahous]

Hello, I have a problem with the NOYAFA NF388, I place the cable and when doing WireMap I do not get any adapter while the cables are still on

[MAdel-qilg]

If you allow to do a test on the COXL cable, it says coxl / Tel Test: open and I want to know that this is a job or not

[tfotocom]

что означают моргающие линии при тесте?
What do the blinking lines mean during the test?

[melucca]

When connecting the NF-388-R (Remote) the main module has the following message "NO ADAPTER"
When I activate the calibration option, it informs the following message "CABLE TOO SHORT!"
What can I do to solve the problem?

[savertech]

Hello, can the lenght test and toning test be also used in coax cable or only on the network cable?

[DanielSunBerlin]

Hi, why it only tests 1-8 of RJ45 and not the shielding too? Thats a big fail, so i need a second device for full testing :(

Or I'm doing something wrong?

[svnetwork-especialistasenr]

i have a problem with this NF-388 NOYAFA, this doesn't work just mention an EXTERNAL VOLTAGE and it doesn't let me work on any option.. Can you help me with my problem?
