contain the user's own replacement parts.
For your safety, please bear in mind "safety first":
Voltage over 30V AC or 60V DC can cause electric shock.
The use of appropriate personal protective equipment, such
as: safety glasses, masks, insulation gloves, insulation boots and
insulation pads.
When charged, don't make yourself grounded.
When using the crocodile clip test line or adapter jumper, always
connect the ground wire to the zero line.
Summary
This instrument is a multi-functional handheld cable testing tool.
The cable type is enhanced, the function is more, and the scope
of application is wider. It is a necessary testing tool for Telecom
engineers, wiring engineers, network maintenance personnel,
etc..
major function
Line finding function: it can directly find the line of RJ11,
RJ45 and BNC interface cable, and can find the line of other
metal wire through adapter.
When the cable line is searched, it is not necessary to peel
off the outer line of the line, so it is simple, fast and can judge the
location of the breakpoint of the line.
It can be used to find the line of any weak Ethernet device,
such as Ethernet switch, router and so on.
Detecting network cable: it can detect the line sequence of
the network cable completely, detect the disconnection, short
circuit, wrong, reverse connection and winding error of the
network cable.
Line level and positive and negative polarity detection.
The telephone line state detection: telephone line state
detection work in (idle, ring, hook) and distinguishing the TIP or
RING line.
Continuous (pass) detection of conductors.
Connection between network cable and switch port.
It has the function of low voltage prompt, and the receiver
has the function of illuminating lamp.
