I have bought a network cable tester and in the manual it said that all lights from 1-8-G should light up in sequence. However I get only 8 without G, although the cable is in working condition.
Here is a picture of the manual:
The product's model is NS-468. If you have the same product, can you tell me what is wrong and what G is intended for?

There is nothing wrong with your tester.
There are 8 strands in an unshielded network cable which is what you tested in your video.
A shielded cable also has a grounded metal sheath surrounding the 8 strands. The G on your tester refers to this.
I have a similar tester but in mine the shield is referred to as "Shield".

I was curious how the tester would even test this, since there's only 8 pins on the RJ45. A shielded cable requires a connector with a metal wrap like this for the shield to connect with, and the tester in turn has a contact for the metal wrap on the connector: https://i.stack.imgur.com/Pju2u.jpg
– AaronLS – 2017-01-24T05:01:20.400G refers to metal sheath? If so, why it does not blink? – Boris_yo – 2011-09-30T18:34:12.523
The cable in your video doesn't appear to have one, it's unshielded. – Tog – 2011-09-30T18:36:50.863
There is nothing wrong with that, it is a perfectly valid cable type. – Tog – 2011-09-30T18:42:44.893
Oh i got it now. I was slow back then. – Boris_yo – 2011-10-02T21:09:48.547

In my CHL-468 tester, the G position is not populated by an LED. I actually soldered in an LED and got it to work.

G = ground => for STP (Shielded Twisted Pair) Most common use is unshielded. – Fiasco Labs – 2016-03-16T19:57:16.407
