The auditor is to sufficiently test the 8 wires for continuity and interchange. No damping resistors or as expected tested. For outdoor installation, wall opening and / or distances over 50 meters you should already use a better device here.
The black clamp is very helpful to the Außenumantelung from CAT5 to CAT7 to remove to get to the wire pairs. With these pliers you have the opportunity before crimping the wire pairs to straighten them cleanly inserted into the RJ45 connector and crimp. As I can not yet assess safe keep the knife land.
With the LSA tool I hung 2 network outlets and patch panels. Even cutting off the wire ends worked as usual.
Solely the crimping tool had cost me 8 connector. First I had doubted me. But then I realized that these pliers the plug and their contacts not Crimps but destroyed. For more detailed study, I found out the two teeth are crooked and the plug can be pushed too far forward (so that it bites into the plastic rather than the pins). Goodness thanks to I had found my old Crimpzange of my apprenticeship.
As can be seen the other recessions there with this set every now and then a few weaknesses. However, you can also get lucky and everything is OK.
For home use, perfectly adequate. Very high-quality tool for professional use should be expected in any way.
