LCD Network Cable Tester B

Second, it has band English. Roughly translated, it means:
1) Warranty void of you break it
2) Make sure the cable has no voltage in it or else

One good thing is that it can also double up as
an audio emitter for a cable tracer probe

Although the instruction says the standby period is
impressive, if you leave it on, the batteries would
be exhausted after two days

The design flaw? If you need to test the cable far away
and not like a loop, you need two of the same thing
Now, that is very very expensive. But if you
compare that to the normal network tester,
the cost is about 30% more?
